Abstract Based on a novel approach, this study explores feasibility and relevance of an inhibition task for studying age-related differences in motor inhibition during gait initiation. When presented with a go-signal, young adults (YA, n = 24) and older adults (OA, n = 55) were required to promptly initiate gait. Participants completed 3 blocks of 12 gait trials. Each block contained 3 stop trials in which the go-signal was followed by a stop-signal that required the person to block gait initiation and remain standing. Stop-signals were presented randomly and with different delays. Data analyses focused on changes in the centre of pressure (COP) and success of motor inhibition. Compared to go-trials, stop trials resulted in a marked decrease of timing and amplitude of COP displacement. Overall success rate of motor inhibition was low (29% in YA vs. 19% in OA) and decreased with increasing COP displacement. Inhibitory success was associated with two strategies: a pro-active cautious COP displacement; and the inhibition of further COP displacement after a stop-signal. Results demonstrate age-related differences in adaptive behavior as well as boundaries beyond which neither old nor young persons were successful. This study yields important insights into motor inhibition during gait and essential input nto further studies.

It is believed that bilingualism contributes to the enhancement of executive functions in bilingual individuals as they need to constantly control the simultaneous activation of two or more languages in their brains. However, decades of research have led to contradictory conclusions regarding the existence of bilingual advantage. One of the promising approaches to resolving these contradictions is a more detailed examination of bilingual language experience. The aim of this study was twofold. First is to empirically test the language entropy method as a way of measuring variability in bilingual language use in different interaction contexts. Second is to examine the relationship between bilinguals’ language entropy and executive functions (cognitive flexibility, goal maintenance, conflict monitoring). The study involved 111 bilinguals (mean age = 20.5 (2.97); 75.7% female), who are speakers of Adyghe-Russian and Tatar-Russian languages. The battery of instruments included a questionnaire on demographic and language experience, containing questions to calculate language entropy in four contexts (home, university, work, free time), a Color-shape switching task to measure executive functions (domains of cognitive flexibility, goal updating, conflict monitoring), and Cattell Culture Fair Intelligence Test to assess nonverbal intelligence. The results demonstrated that language entropy of the bilinguals from both regions did not exceed a score of 0.66 in all the contexts which indicates the use of predominantly one language in everyday communications. However, in the “university” context, bilinguals speaking Tatar and Russian used languages in a more balanced way than bilinguals speaking Adyghe and Russian languages. The results suggest that the language entropy method can be highly effective for characterizing bilingual language experience. The results also showed that there was no relationship between language entropy of the bilinguals in this study and their executive functions (domains of cognitive flexibility, goal updating, conflict monitoring). This is consistent with the predictions of the Adaptive Control Hypothesis.

The aim of this study was to compare the effectiveness of aerobic exercise training, mindfulness and a combination of mindfulness and exercise training on the executive functions of fourth-grade female students. The method was semi-experimental, utilizing a pretest–posttest design with a control group. Subsequently, 18 30-minute training sessions were developed and implemented on intervals of every two days. The data were obtained through the Free Research Executive Function Evaluation (FREE) test. SPSS22 was employed to conduct multivariate analysis of covariance (MANCOVA) on the data. The results indicated that the inhibition of students in all three programs—aerobic exercise training (Eta=0.18), mindfulness (Eta=0.26), and combined mindfulness and exercise training (Eta=0.76)—is significantly different from that of the control group (p

Abstract Behavioral variant frontotemporal dementia (bvFTD) is characterized by profound and early deficits in social cognition (SC) and executive functions (EF). To date it remains unclear whether deficits of the respective cognitive domains are based on the degeneration of distinct brain regions. In 103 patients with a diagnosis of bvFTD (possible/probable/definite: N = 40/58/5) from the frontotemporal lobar degeneration (FTLD) consortium Germany cohort (age 62.5±9.4 years, gender 38 female/65 male) we applied multimodal structural imaging, i.e. voxel-based morphometry, cortical thickness (CTH) and networks of structural covariance via source based morphometry. We cross-sectionally investigated associations with performance in a modified Reading the Mind in the Eyes Test (RMET; reflective of theory of mind - ToM) and five different tests reflective of EF (i.e. Hamasch-Five-Point Test, semantic and phonemic Fluency, Trail Making Test, Stroop interference). Finally, we investigated the conjunction of RMET correlates with functional networks commonly associated with SC respectively ToM and EF as extracted meta-analytically within the Neurosynth database. RMET performance was mainly associated with gray matter volume (GMV) and CTH within temporal and insular cortical regions and less within the prefrontal cortex (PFC), whereas EF performance was mainly associated with prefrontal regions (GMV and CTH). Overlap of RMET and EF associations was primarily located within the insula, adjacent subcortical structures (i.e. putamen) and the dorsolateral PFC (dlPFC). These patterns were more pronounced after adjustment for the respective other cognitive domain. Corroborative results were obtained in analyses of structural covariance networks. Overlap of RMET with meta-analytically extracted functional networks commonly associated with SC, ToM and EF was again primarily located within the temporal and insular region and the dlPFC. In addition, on a meta-analytical level, strong associations were found for temporal cortical RMET correlates with SC and ToM in particular. These data indicate a temporo-frontal dissociation of bvFTD related disturbances of ToM and EF, with atrophy of the anterior temporal lobe being critically involved in ToM deficits. The consistent overlap within the insular cortex may be attributable to the multimodal and integrative role of this region in socioemotional and cognitive processing.

Abstract Background Diagnosing neurodevelopmental disorders can sometimes be challenging, especially when the clinical presentation is different from what is normally observed. Evaluating executive functions can provide valuable information about children’s and adolescents’ mental states. There is no available executive function rating scale for Azerbaijani. From this perspective, there is great utility in translating and validating the Barkley Deficits in Executive Functioning Scale – Children and Adolescents (BDEF-CA). For this research, we decided to use the short form of the BDEF-CA. The rating scale was translated into the Azerbaijani by a bilingual clinical psychologist and by a professional translator. After performing backward translation, the final version was prepared, read and approved by two professors in the psychology department at the university. The study population included 148 parents of children aged 6-17 years (78 males and 70 females). Results The findings of this research support the validity and reliability of the Azerbaijani translation of the BDEF-CA short version (Cronbach’s alpha and McDonald’s omega coefficient were both greater than 0.9, and Confirmatory Factor Analysis (CFA) results indicated an adequate fit). Conclusion The short version of the Azerbaijani translation of the BDEF-CA could be used for assessing executive functioning deficits in children and adolescents.

Abstract The cultural background and age shape the cognitive and social development of children. This study aimed to compare perceptual, executive, and social functioning in two age groups of preschoolers from Germany and Iran. One hundred sixty-five children (83 Iranian and 82 German) participated in the study, with 87 children aged three years and 78 children aged four years. The participants completed a series of tasks to assess different cognitive functions, including the theory of mind as a measure of social cognition, picture mental rotation test to evaluate spatial ability, and several tests including digit span, Corsi block tapping, day-night, grass-snow, dimensional change card sort, and active and passive vocabulary tests to assess executive functions. The findings revealed that German children performed better than their Iranian peers regarding spatial ability and theory of mind. Additionally, German children outperformed Iranian children in working memory, cognitive flexibility, and verbal fluency, while Iranian children demonstrated better inhibitory control. Furthermore, the correlational analysis indicated that in German children, executive function correlated with the theory of mind, whereas in Iranian children, executive function was associated with perceptual functions. Age impacted the results. These results highlight the role of cultural factors in shaping cognitive functioning and emphasize the need to consider cultural influences when examining cognitive development in different populations.

Abstract Background Postural control is dependent on the central nervous system’s accurate interpretation of sensory information to formulate and execute adequate motor actions. Research has shown that cognitive functions are associated with both postural control and fall risk, but specific associations are not established. The aim of this study was to explore how specific components of everyday postural control tasks are associated with both general and specific cognitive functions. Methods Forty-six community-dwelling older adults reported their age, sex, physical activity level, falls and fall-related concerns. The following cognitive aspects were assessed: global cognition, executive functions, processing speed and intraindividual variability. Postural control was quantified by measuring postural sway in quiet stance, walking at a self-selected pace, and walking while performing a concurrent arithmetical task. Separate orthogonal projections of latent structures models were generated for each postural control outcome using descriptive and cognitive variables as explanatory variables. Results Longer step length and faster gait speed were related to faster processing speed and less intraindividual variability in the choice reaction test. Moreover, longer step length was also related to less fall-related concerns and less severe fall-related injuries, while faster gait speed was also related to female sex and poorer global cognition. Lower dual-task cost for gait speed was explained by the executive function inhibition and faster processing speed. Postural sway in quiet stance was not explained by cognitive functions. Conclusions Cognitive functions explained gait speed and step length during normal walking, as well as the decrease of gait speed while performing a concurrent cognitive task. The results suggest that different cognitive processes are important for different postural control aspects. Postural sway in quiet stance, step time and gait variability seem to depend more on physical and automatic processes rather than higher cognitive functions among physically active older people. The relationships between cognitive functions and postural control likely vary depending on the specific tasks and the characteristics of different populations.

Introduction: The aim of this study was to investigate the effectiveness of joint attention training on basic social communication, anxiety and executive functions of children with autism. Methods: The research design was quasi-experimental and pre-test and post-test with control group. The statistical populations of children with autism spectrum were referred to the psychiatric and psychological centers in Urmia City during the year 2021-2022. 30 individuals (15 ones from the shared attention group and 15 from the control group) were selected as a statistical sample using the available and targeted method. Data via questionnaires of basic social communication (Zabov, 2010), anxiety (Spence, 1999), executive functions of the parents' brief form (Balster Gerard et al., 2000) were collected during the intervention therapy method of joint attention training (Vakilizad and Abedi, 2015) (12 sessions, 3 days a week, each session was an hour and a half, each session was divided into 3 parts of 25 minutes with a 5 minute break for the child). Then the data were analyzed with Software SPSS V. 16 and multivariate analysis of covariance test. Results: The results showed that joint attention training increased basic social communication and executive functions and reduced anxiety in children with autism spectrum. The differences between the investigated groups and the conducted tests were significant (P≤0.01). Conclusion: Interventional treatment methods such as joint attention training should be developed for the treatment of autistic patients, so that with the help of these methods, the individual and collective life of these patients can be improved.

Abstract Background Considering the importance of cognitive and motor functions of the elderly people, the present study was conducted to evaluate the effectiveness of a cognitive exergame, called Neurolight compared to computerized cognitive games, in enhancing core executive functions and motor performance. Methods A total of 36 individuals in the age range of 60 to 69 years were studied in the form of three groups: The control group continued their daily activities, while the Neurolight group underwent a cognitive-motor training and the Maghzineh performed a computer-based cognitive training program for 24 sessions. Before and after interventions, working memory, inhibitory control, and balance were measured respectively by the N-back, Stroop, and TUG tests. Results The results showed that cognitive-motor exercises using Neurolight, for 24 sessions, were able to significantly improve working memory, inhibitory control, and balance in individuals in this age group. Conclusion This finding supports the other studies suggesting combined cognitive and physical exercises for better effect. Based on its findings, the use of this exercise system can be suggested to coaches and therapists working with the elderly.

Abstract This study examined the impact of sport-specific cognitive training (CT) on executive functions (EFs) in youth soccer players. Thirty-one athletes (13–15 years) participated, 13 in the intervention group (IG) and 18 in the control group (CG). The IG underwent an 8-week soccer-focused CT program, while the CG maintained regular training. The assessments included working memory, inhibition, and cognitive flexibility tasks. The results revealed no significant improvements in EFs in the IG compared to those in the CG. Both groups showed enhanced cognitive flexibility, possibly due to general cognitive development or learning effects. The study suggested that an 8-week sport-specific CT may not enhance EFs in young soccer players, potentially due to a ceiling effect in highly skilled athletes. These findings should be considered when designing cognitive training programs for athletes, and future research could explore the optimal duration of such programs.

Abstract Our research aimed to identify interrelationships between performance in the Stroop test and emotion regulation and academic achievement of students. The present research method was descriptive of correlation type. The statistical population in this study included all students of Mashhad in Iran. Using the cluster sampling method and within each cluster using random sampling method, 120 students were recruited from three different educational levels. In this study, the Stroop test, Cognitive Emotion Regulation Questionnaire (CERQ-P), and GPA of the students were used to measure the research variables. To analyze the data, a multivariate regression statistical model was used to determine the relationship between the desired variables. The analysis shows that there is a significant relationship between academic achievement and performance on the Stroop test and emotion regulation (p

Abstract While previous research has identified executive functions as predictors of academic performance in school children, similar studies conducted among adults show mixed results. One of the reasons given for executive functions having a limited effect on academic achievements in adulthood is that they are usually fully developed by that time. Since these executive functions are at their peak at that age, the individual differences in these as well as their influence on academic performance in adults are harder to trace. The paper describes a study conducted among 107 university students the goal of which was to find out whether there is any relationship between the adult students’ inhibitory control values measured with the Stroop Test and their academic achievements. Although the results indicate a weak correlation between the Stroop Effect and the students’ academic performance of low statistical significance, which seems to confirm the outcomes of the previous studies focusing on adults, the study reveals an unexpected statistically significant correlation between the students’ grade averages and the number of their incorrect color identifications. This phenomenon appears to be worth pursuing in future research since it suggests the existence of another, relatively quickly measurable, variable possibly reflecting other predictors of academic performance in adults such as a degree of their manifested conscientiousness, their ability to concentrate on an assigned, relatively short, one-off task and their attitude to fulfilling this task. The Stroop Test, despite not being originally designed for this purpose, might thus be used as a simple tool suitable for providing information about these variables via the subject’s number of color identification errors. Such information can subsequently inform the activities that educators may include in their curricula to foster conscientiousness and concentration in the students lacking these.

Cognitive evolution, as the core subject of fields like paleoanthropology, cognitive archeology, and neuropsychology, has begun to gain more interest in psychology in recent years. Executive functions are viewed from the perspective of cognitive evolution as basic advancements that are crucial to the evolution of language and contemporary cognition. As a metaphor, executive functions refer to advanced cognitive processes (working memory, inhibition, organization, cognitive flexibility, etc.) in the context of complex goal-directed behaviors. Sophisticated cognitive traits like executive functions emerged because of solutions to adaptive issues (survival, reproduction, and social group life) that human ancestors confronted over millions of years and passed them on to their offspring. Although it is accepted that Homo sapiens owes its evolutionary success to Paleolithic living conditions, explaining this process has not always been easy. In this review article, general information about executive functions is presented, followed by a review of scientific explanations about the evolution of executive functions. Evaluations have shown that these alternative scientific explanations based on archaeological, anthropological, and neuropsychological evidence for the evolutionary origins of executive functions do not fit all the pieces of the puzzle. It is believed that novel research models will clarify which of these alternative explanations are proximate causes and which are ultimate causes.

Background: Methamphetamine addiction is a growing global concern associated with executive dysfunctions that negatively impact daily life. Traditional tests for assessing executive dysfunctions are often complex and time-consuming. Therefore, a valid, reliable, and simple instrument to assess these dysfunctions is crucial. This study aimed to assess the psychometric properties of the Persian version of the Dysexecutive Questionnaire in methamphetamine-abstinent individuals.Methods: A cross-sectional study was conducted with 100 participants aged 20 to 50, selected via convenience sampling. The Dysexecutive Questionnaire (informant and occupational therapist ratings), Behavioral Assessment of the Dysexecutive Syndrome, Stroop test, Wisconsin Card Sorting test, and Tower of London task were used to evaluate the participants. The study examined the face validity, convergent validity, internal consistency, test-retest reliability, and inter-rater reliability of the Dysexecutive Questionnaire. Data analysis was conducted using SPSS v.23.0 at a significance level 0.05.Results: The Dysexecutive Questionnaire demonstrated acceptable face validity (impact score: 1.95 to 3.86). Convergent validity was supported by significant correlations between the Dysexecutive Questionnaire - informant rating and other assessment tools (p < 0.001). The questionnaire showed good to excellent internal consistency (Dysexecutive Questionnaire - occupational therapist rating: α = 0.91; Dysexecutive Questionnaire - informant rating: α = 0.87). The test-retest reliability was high for the occupational therapist rating (ICC = 0.911) and informant rating (ICC = 0.925). Inter-rater reliability was also excellent (ICC = 0.980).Conclusion: The Dysexecutive Questionnaire - informant rating is a reliable and valid instrument for evaluating dysexecutive symptoms in methamphetamine-abstinent individuals.

Abstract Background This study aimed to investigate the cognitive and affective factors associated with cross-cultural differences in arithmetic tasks. Methods A total of 404 third- and fourth- graders were recruited from China and Italy to complete exact arithmetic, arithmetic estimation and cognitive tasks (i.e., short-term memory, executive functions, and fluid reasoning). Their mathematical anxiety was also measured. Results The results showed that Chinese children performed better than Italian children in both arithmetic tasks and in shifting task. Italian children performed better in visuospatial updating task and reported higher levels of mathematical anxiety than their Chinese peers. Multi-group path analyses showed that the patterns of relations among cognitive factors (i.e., short-term memory, inhibition and shifting), mathematical anxiety, and arithmetic performance were similar across groups. The only exception was that visuospatial updating uniquely predicted arithmetic estimation for Chinese but not for Italian children. Conclusions Chinese children outperformed their Italian peers in the exact arithmetic task, likely due to the greater emphasis on arithmetic fluency in Chinese mathematics education, both in schools and at home. They also had a slight advantage than Italian peers in the arithmetic estimation task. The unique link between updating and arithmetic estimation found in Chinese children but not Italian children suggests that, although arithmetic estimation is not emphasized in the curricula of either country, instruction and practice in exact arithmetic may enhance Chinese children’s efficiency in solving arithmetic estimation problems.

The aim of the study was to predict social adequacy based on positive and negative symptoms with the mediating role of executive functions in patients with schizophrenic. The population included all schizophrenic patients in Isfahan who were hospitalized in Modares and Farabi hospitals and were not in the acute stage of the disease at the time of the research. 129 people, i.e. 66 women and 63 men, were selected based on the criteria for entering the study by purposive sampling. Felner's Social Adequacy Questionnaire (1990), Nejati Executive Workers Questionnaire (2013), and Andreessen's Positive and Negative Symptoms Scale (1984) were used. The resulting data were analyzed at two descriptive and inferential levels. Hypotheses were tested using structural equations and path analysis. The results showed that the prediction model of social adequacy based on positive and negative symptoms of schizophrenia with the mediating role of executive functions has a favorable fit and executive functions can play a mediating role in the relationship between variables of negative symptoms and social adequacy (P

Abstract Purpose This study explores the relationship between sensorineural hearing loss (SNHL) in mid-life adults and cognitive function, focusing on executive functions. Given the projected rise in dementia cases, identifying modifiable risk factors for cognitive decline is imperative. SNHL has emerged as a potential risk factor, with hearing loss accounting for a substantial portion of dementia cases. However, the cognitive implications of SNHL in mid-life adults are not well understood. Method The study examined 50 participants, 25 with bilateral unaided mild SNHL (AHL) and 25 with normal hearing (ANH). A battery of audiological assessments and cognitive tests, including the Trail Making Test (TMT), was administered. TMT measures included direct scores (completion time and errors) and derived scores (difference, ratio, proportion, sum, and multiplication scores). Results The AHL group displayed significantly poorer peripheral hearing compared to the ANH group, as reflected in pure-tone audiometry, speech reception thresholds, and speech identification scores. Significant differences were observed in all direct and derived TMT measures except for the ratio and proportion scores. This suggests that while overall cognitive disturbances were evident in the AHL group, they were not exclusive to executive function deficits. Notably, we did not identify any statistically significant effects of hypertension, diabetes, smoking, alcohol consumption, or physical activity on TMT scores. Conclusion This study highlights the potential impact of SNHL on cognitive function in mid-life adults. Mid-life SNHL is associated with cognitive differences, emphasizing its role as a modifiable risk factor for future cognitive decline. This research underlines the need for further investigation into the cognitive effects of aided hearing and a multidisciplinary approach to understanding these alterations in cognitive function.

Abstract Background Interventions focused on cognitive function in neurodivergent children typically focus on single functions, e.g. working memory training. They are often focused on ‘deficit’ models and lack an emphasis on understanding areas of individual strengths and difficulties as a prerequisite to appropriate support. The multidimensional nature and phenotypic variability of cognitive profiles in these children indicate a need for a multicomponent-tailored intervention programme focused on understanding and supporting an individual child’s cognitive functioning. Aims The ‘EPIC’ intervention (Edinburgh Psychoeducation Intervention for Children and Young People) is focused on improving cognition, learning and behaviour in neurodivergent children such as those with attention deficit hyperactivity disorder (ADHD) or who are autistic. Building on our previous co-production work, this study aimed to use a participatory methods approach to develop EPIC practices and materials in relation to our key principles which include psychoeducation, multicomponent, individualised approach, strengths and difficulties profiling and pairing of a child’s individual strengths and difficulties with internal and external strategies. We also set out to assess the feasibility and acceptability of EPIC, and pilot this novel tool-kit intervention with neurodivergent children and their parents and teachers. Methods The intervention practices, materials and strategies of EPIC were co-produced with neurodivergent children, their parents, teachers and clinicians taking a strengths and difficulties approach. Identification of psychoeducation activities and strategy practices (e.g. mind-maps, chunking), testing of feasibility and collection of pilot data were conducted over a bi-weekly 8-week programme. Eleven neurodivergent children aged 7 to 12 completed the 16-session individualised programme. Acceptability and feasibility were ascertained via qualitative reports elicited within child and teacher interviews and child ratings of enjoyment. Pilot evaluation data was collected pre- and post-intervention participation, and across cognitive assessments (CANTAB, BRIEF), educational attainment (WIAT) and parent and teacher questionnaires measuring clinical symptoms and behaviour (Conners, AQ, SDQ, self-perception). Data was compared with a matched neurodivergent treatment-as-usual control group (N = 9). Results The co-produced EPIC intervention was both feasible to deliver and acceptable to children, parents and their teachers. Pilot data identified that the 8-week intervention improved cognition (short-term and working memory) and literacy (receptive vocabulary, oral word fluency, listening comprehension). Improvements in the intervention group were also found for parent-reported child behavioural difficulties and aggression, and teacher-reported scholastic competence. Effect sizes generated (Cohen’s d) ranged from 0.65 to 2.83. Parents reported continuing to use EPIC strategies when interviewed over a year after participating in the programme. Conclusion The current study met our objectives fully. ‘EPIC’ (Edinburgh Psychoeducation Intervention for Children and Young People) is feasible in home and school contexts and improves a range of aspects of cognition, learning and behaviour in neurodivergent children. Our findings show EPIC is suitable to be assessed within a full-scale trial.

Background. Raven’s Coloured Progressive Matrices (RCPMs) is a widely used instrument as one of psychometric measures of general intelligence in children. However, according to some researchers, the RCPM is heterogeneous and individual tasks may be associated with the assessment of various cognitive components. Objective. This study is aimed to examine the influence of functions of visual and visuospatial processing, and executive functions on the productivity of RCPMs. Sample. A total of 297 children from 6 to 9 years old participated in the study. Of these, 98 were preschoolers, 87 first graders and 112 second graders. A total of 152 boys and 145 girls participated in the study. All children had no diagnosed developmental and neurological disorders. Methods. All the children accomplished the computerized version of RCPM in the Rosanova’s modification. They also passed a neuropsychological assessment adapted for 6–9-year-old children. Results. Age differences were shown. They were the greatest when comparing preschoolers and first-grader. The differences between first-graders and second-graders were less prominent. Hierarchical regression analysis showed that three parts of the matrices are related to separate groups of functions to different degrees. The first part of the test is most related to the state of visual information processing functions; the second part refers to the state of visual-spatial information processing and executive functions; and the third part to a greater extent deals with the state of executive functions. Conclusion. The results indicate the heterogeneity of tasks in RCPM and the promise of a more detailed analysis of the structure of the technique, including the use of a neuropsychological approach.

Background: Identifying the theoretical frameworks and intervention components in socio-economically deprived communities to improve their performance in various aspects of development, can be effective. Therefore, there is a need to review more recent literature that reports the effectiveness of interventions for people living in a socio-economically deprived society. This study aimed to investigate the effect of teaching games for understanding approach on fundamental motor skills and executive functions in economically deprived children.Methods: This quasi-experimental research was an applied one in terms of purpose with a pre-test and post-test design. For this purpose, thirty 7 to 9-year-old children from the economically deprived areas of Kahnouj City were randomly assigned into two groups including the non-linear approach (the teaching games for understanding) and the linear approach. The research participants were trained for eight weeks. Before and after the eight weeks of training, the test of gross motor development-2 and the executive functions questionnaire scores were recorded.Results: The results of this research showed that the teaching games for understanding approach compared to the linear approach has a greater effect on the subscales of fundamental motor skills and executive functions of economically deprived children (P≤0.05).Conclusion: Engaging in cognitive activities in the teaching games for understanding approach improves fundamental motor skills and executive functions.

Background: Any high-risk behavior can cause serious and sometimes irreparable harm to the individual and family. High-risk behavior often occurs in an emotionally-charged context, and executive functions and emotion regulation play important roles in risk-related decision making. Therefore, identifying the factors that facilitate and sustain risky behaviors in different groups is an inevitable necessity. Aims: The aim of this study was to investigate the structural relationship between executive functions and high-risk behaviors in prisoners considering the mediating role of emotion regulation strategies. Methods: The present study is descriptive and correlational, conducted by structural equation modeling method. The statistical population of this study is all prisoners in Shiraz city. The sample consisted of 409 prisoners in Shiraz who were selected by purposive sampling. Data were collected using Cognitive Abilities Questionnaire (Nejati 2013), Emotion Regulation Strategies (Garnefski et al., 2001), and Youth Risk Behaviors Scale (Snow et al., 2019). To evaluate the proposed model, structural equation modeling was used using AMOS version 24 and SPSS 27. Results: The results of correlation coefficient showed that there is a negative relationship between executive functions and adaptive emotion regulation strategies with risky behaviors (P< 0.05). Also, there is a positive and significant relationship between maladaptive emotion regulation strategies and risky behaviors (P< 0.05). The findings indicate that the proposed model is fitted with the data. The results of the structural model showed that 19% of the variance of adaptive strategies and 25% of variance of maladaptive strategies is explained by executive functions and 45% of variance of risky behaviors is explained by executive functions and adaptive and maladaptive strategies of emotion regulation. Conclusion: It can be concluded that risky behaviors are affected by cognitive and emotional functions and cognitive emotion regulation strategies have a mediating role in this regard, which requires psychological interventions. Our results suggest that treatment for high-risk behavior may be more effective with a nuanced approach that does not conflate high impulsivity necessarily with high-risk behavior tendencies.

The diversity of cognitive skills across primates remains both a fascinating and a controversial issue. Recent comparative studies provided conflicting results regarding the contribution of social vs ecological constraints to the evolution of cognition. Here, we used an interdisciplinary approach combining comparative cognitive neurosciences and behavioral ecology. Using brain imaging data from 16 primate species, we measured the size of two prefrontal brain regions, the frontal pole (FP) and the dorso-lateral prefrontal cortex (DLPFC), respectively, involved in metacognition and working memory, and examined their relation to a combination of socio-ecological variables. The size of these prefrontal regions, as well as the whole brain, was best explained by three variables: body mass, daily traveled distance (an index of ecological constraints), and population density (an index of social constraints). The strong influence of ecological constraints on FP and DLPFC volumes suggests that both metacognition and working memory are critical for foraging in primates. Interestingly, FP volume was much more sensitive to social constraints than DLPFC volume, in line with laboratory studies showing an implication of FP in complex social interactions. Thus, our data highlights the relative weight of social vs ecological constraints on the evolution of specific prefrontal brain regions and their associated cognitive operations in primates.

Objective: This study investigated the weight of different cognitive disorders on patient behaviour influencing the risk of falls after recent stroke. Design: Survey and retrospective monocentric study. Subjects/patients: 74 professionals/108 patients. Methods: Survey of professionals to ask for their thoughts concerning the weight of different cognitive disorders on the risk of falls and a retrospective study of patients post-stroke to determine whether these cognitive deficits could distinguish fallers from non-fallers. Univariate and multivariate logistic regression analyses were conducted. Results: In part 1, major cognitive disorders identified were anosognosia, confusion, inattention, precipitation, and unilateral spatial neglect. In part 2, 25 patients (23%) were fallers. After adjustment for length of rehabilitation stay and disease severity, on multivariate analysis, the cognitive disorders significantly associated with risk of falls were anosognosia (odds ratio 16), precipitation (13.3), inattention (8.3), and perseveration (4.9). Unilateral spatial neglect was not independently associated. Aphasia did not play a role. Conclusion: Some cognitive disorders, easily identified before any neuropsychological assessment, strongly modify patient behaviour in terms of risk of falls. It is proposed that these disorders should not be considered as an additional factor along with physical and general factors but rather as a multiplying factor applied to the others.

Introduction: Executive function deficits are associated with attention deficit hyperactivity disorder (ADHD) in both children and adults. The inattentive subtype is primary related to “cold” executive functions, while the hyperactive subtype is related to “warm” executive functions. Objective: To systematically review studies on executive functioning in adults with attention deficit hyperactivity disorder published during the last decade. Methodology: A documentary research was conducted, encompassing 33 articles retrieved from PubMed, Web of Science and EBSCO platforms. The analysis considered years and countries of publication, attention deficit hyperactivity disorder diagnostic criteria, participants, comorbidities, subtypes, medication use, assessment tools, and processes of executive functions evaluated. Results: It was evidenced that there is a high percentage of adults with attention deficit hyperactivity disorder who present a deficit or lower performance in executive function tests. However, the results varied depending on specific characteristics of the study and/or participants, which confirms the heterogeneity of the disorder. In addition, the main instruments for measuring executive functions and diagnostic criteria for adult attention deficit hyperactivity disorder were identified. Discussion: These results support the established links between attention deficit hyperactivity disorder , impaired executive functions, and major life activities found in the adult attention deficit hyperactivity disorder literature. However, some of the limitations were the poorly controlled variables such as comorbidities, attention deficit hyperactivity disorder subtypes that were not assessed, and usage of instruments that measure executive functions that can lead to reduced credibility of the results presented here. Conclusions: According to the results presented, there is a high percentage of adults with attention deficit hyperactivity disorder who present a deficit or lower performance in executive function tests, compared to both neurotypical adults and those with other psychiatric disorders. Further research is recommended to continue studies on the topic and to include other variables.

Students with learning disabilities often experience a complex range of internal and external challenges that can significantly impact their overall well-being and development. Internally, these students may grapple with intense feelings of anxiety, depression, and physical complaints, which can lead to social withdrawal and diminished self-esteem. They may also face higher rates of bullying and social rejection, further exacerbating their psychosocial difficulties and negatively affecting their sense of belonging and acceptance. These learners are more likely to exhibit attention problems, poor concentration, and a wide range of emotional difficulties, which can further hinder their ability to engage effectively in academic and social settings. Behaviorally, students with learning disabilities may exhibit issues like attention deficits and socialisation challenges, stemming from underlying processing difficulties and challenges in understanding social cues and norms. They may also experience feelings of anger, frustration, and even aggressive behaviours, often as a result of their negative experiences and struggles with academic demands. Emerging research suggests that executive function deficits can contribute to these students' complex relationship between temperament and psychological difficulties. Problems with executive functions, such as attention, planning, memory, and flexibility, can significantly impact their cognitive and social-emotional development. Early interventions, such as video games, mobile apps, or STEM-oriented approaches, are crucial for addressing these multifaceted challenges and supporting the holistic growth and well-being of students with learning disabilities

There is increasing evidence that using more than one languages has significant effects on brain function. These effects have been observed in the developing, adult and aging brain, and have been suggested to have implications for cognitive and brain decline in bilinguals and multilinguals. Aside from extensive investigations with behavioral methods, such effects are now commonly investigated with functional neuroimaging methods, mostly functional Magnetic Resonance Imaging (fMRI) and electroencephalography (EEG). A relatively underused method in the field is functional Near-Infrared Spectroscopy (fNIRS), which carries several advantages over more established methods, including being appropriate for use with infants and children, but also with older and diseased samples. This paper provides an overview of the method and an account of how it has been used in the field of bilingual cognition. It concludes with suggestions of how the method can be best utilized in future research, highlighting it as a method with a strong potential for updating existing theories on the effects of bilingualism on brain function.

IntroductionRecent research has recognized executive dysfunction as another component affected in Primary Progressive Aphasia (PPA). This systematic review aimed to examine what information distinctive neurophysiological markers can provide in the evaluation of executive function (EF) deficits in PPA, and to what effect executive function deficits can be assessed through the characteristics of functional markers.MethodsWe conducted a systematic literature search following the PRISMA guidelines across studies that employed neuropsychological assessments and neurophysiological imaging techniques (EEG, MEG; PET, SPECT, fMRI, fNIRS) to investigate executive dysfunction correlates in PPA.ResultsFindings from nine articles including a total number of 111 individuals with PPA met our inclusion criteria and were synthesized. Although research on the neural correlates of EF deficits is scarce, MEG studies revealed widespread oscillatory slowing, with increased delta and decreased alpha power, where alterations in alpha, theta, and beta activities were significant predictors of executive function deficits. PET findings demonstrated significant correlations between executive dysfunction and hypometabolism in frontal brain regions. fMRI results indicated elevated homotopic connectivity in PPA patients, with a broader and more anterior distribution of abnormal hippocampal connections of which were associated with reduced executive performance.ConclusionOur study provides indirect support for the assumption regarding the significance of the frontal regions and inferior frontal junction in executive control and demonstrates that neurophysiological tools can be a useful aid to further investigate clinical-neurophysiological correlations in PPA.

IntroductionCognitive control is a prerequisite for successful, goal-oriented behavior. The dorsolateral prefrontal cortex (DLPFC) is assumed to be a key player in applying cognitive control; however, the neural mechanisms by which this process is accomplished are still unclear.MethodsTo further address this question, an audiovisual Stroop task was used, comprising simultaneously presented pictures and spoken names of actors and politicians. Depending on the task block, participants had to indicate whether they saw the face or heard the name of a politician or an actor (visual vs. auditory blocks). In congruent trials, both stimuli (visual and auditory) belonged to the same response category (actor or politician); in incongruent trials, they belonged to different categories. During this task, activity in sensory target regions was measured via functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG), respectively. Specifically, fNIRS was used to monitor activity levels within the auditory cortex, while the EEG-based event-related potential of the N170 was considered as a marker of FFA (fusiform face area) involvement. Additionally, we assessed the effects of inhibitory theta-burst stimulation—a specific protocol based on repetitive transcranial magnetic stimulation (rTMS)—over the right DLPFC. Non-invasive brain stimulation is one of the few means to draw causal conclusions in human neuroscience. In this case, rTMS was used to temporarily inhibit the right DLPFC as a presumed key player in solving Stroop conflicts in one of two measurement sessions; then, effects were examined on behavioral measures as well as neurophysiological signals reflecting task-related activity in the frontal lobes and sensory cortices.ResultsThe results indicate a central role of the DLPFC in the implementation of cognitive control in terms of a suppression of distracting sensory input in both the auditory cortex and visual system (FFA) in high-conflict situations. Behavioral data confirm a reduced Stroop effect following previous incongruent trials (“Gratton effect”) that was only accomplished with an intact DLPFC (i.e., following placebo stimulation).DiscussionBecause non-invasive brain stimulation is uniquely suited to causally test neuroscientific hypotheses in humans, these data give important insights into some of the mechanisms by which the DLPFC establishes conflict resolution across different sensory modalities.

Abstract Background Congenital Heart Disease (CHD) is the most common congenital abnormality. Survival rates are over 90%, however infants with CHD remain at high risk of attention and executive function impairments. These abilities are difficult to assess in toddlers because clinical assessments rely on language abilities which are commonly delayed in CHD. Our aim was to characterise visual attention in toddlers with CHD compared to controls and identify associations with parent‐rated effortful control. Methods Thirty toddlers with CHD (19 male, median (IQR) age at assessment 22.2 (22–23.1) months) and 66 controls from the developing human connectome project (36 male, age at assessment 22 (21.5–23.8) months) using eye‐tracking tasks designed to assess multiple components of visual attention. Analyses of co‐variance and regressions were used to identify differences between groups and relationships between gaze behaviours and parent‐rated effortful control. Results Toddlers with CHD were less accurate when switching behaviours (set‐shifting) [median (IQR) 79%, (28–100)] compared to controls [100% (86–100), pFDR = 0.032], with worse accuracy associated with lower parent‐rated effortful control in CHD but not controls (interaction pFDR = 0.028). Reaction times were slower during selective [CHD 1243 ms (986–1786), controls 1065 ms (0851–1397), pFDR

IntroductionThe development of reading and complex executive functions is fundamental for achieving social, academic, and professional success. So far, there is no single neuropsychological instrument that comprehensively assesses the domains of inhibitory control, cognitive flexibility, working memory, and reading comprehension. To assess executive functions related to reading, the “Assessment of Reading and Executive Functions” (AREF) was developed. In this study, we show initial evidence of validity and reliability for four subtests - Graphophonological-Semantic Flexibility, Inhibitory Control, Flexibility, and Working Memory.MethodsA total of 93 students from 4th to 9th grade, aged 8-14, in public (n = 61) and private (n = 32) schools were evaluated. Tasks from the AREF instrument, as well as measures of reading comprehension, inhibitory control, cognitive flexibility, working memory, and intelligence, were administered. Correlations between AREF scores and the other measures were performed to assess external construct validity. Performance differences between school groups on AREF subtests were analyzed using ANOVA, t-test, and Mann-Whitney tests, and the internal consistency of the instrument’s tasks was evaluated using Cronbach’s alpha coefficient.ResultsThe scores of the AREF subtests demonstrated significant positive correlations with reading measures (ranging from 0.339 to 0.367) and executive functions (ranging from 0.209 to 0.396). Significant differences were found in the performance of some AREF tasks when comparing individuals from public and private schools, as well as between 4th and 5th graders compared to students in higher grades. The internal consistency of the tasks was low for Graphophonological-Semantic Flexibility (Cronbach’s α = 0.566), moderate for Inhibitory Control and Flexibility (Cronbach’s α = 0.768), and high for Working Memory (Cronbach’s α = 0.881).DiscussionThe results provide initial evidence of construct validity and reliability for the AREF subtests. It is expected that this new neuropsychological test will contribute to the assessment of reading skills and executive functions, assisting in guiding clinical and educational interventions for individuals with and without neurodevelopmental disorders.

ObjectiveThis study was to investigate the developmental characteristics of executive function (EF) in obese adolescents and the time-course effects of a 14-week exercise intervention combining aerobic exercise and resistance training on EF in this population.MethodsThe experimental group of 28 obese junior high school students participated in the exercise intervention combining aerobic exercise and resistance training, while the control group of 24 healthy weight junior high school students engaged in the regular recess exercise. EF, including inhibition, working memory, and cognitive flexibility, was assessed 1 week prior to the exercise intervention and at 12 and 14 weeks post-intervention. Changes in EF sub-functions in both groups at different time points during the exercise intervention were analyzed.ResultsThe findings revealed that obese junior high school students exhibited lower levels of inhibition (p = 0.003, Cohen’s d = 0.848) and cognitive flexibility (p = 0.013, Cohen’s d = 0.706) compared to their healthy weight peers. The exercise intervention combining aerobic exercise and resistance training led to significant improvements in EF among obese junior high school students, with inhibition (p

BackgroundA large body of research has identified the positive effects of physical activity on children with autism spectrum disorders (ASD). However, the specific benefits of different types of sports on executive functioning in children with ASD remain unclear. The aim of this study was to further analyze the effects of different sports on executive functioning in children with ASD using reticulated meta-analysis and to establish their effectiveness ranking.MethodsThis study conducted a comprehensive online search in Web of Science, PubMed, Cochrane, Embase, and CNKI databases. It included randomized controlled trials and quasi-experimental studies, and synthesized the data using a Bayesian framework.ResultsSeveral relevant studies were included. The results showed that physical activity significantly improved all three dimensions of executive functioning (inhibitory control, cognitive flexibility, and working memory) in children with ASD. The improvement in cognitive flexibility and inhibitory control both reached a medium effect size. However, the improvement in inhibitory control was better than that in cognitive flexibility, while the improvement in working memory did not reach the level of a medium effect. Mini Basketball was effective in improving inhibitory control and cognitive flexibility, but not working memory. Ping Pong was more effective in cognitive flexibility and working memory, but weaker in inhibitory control. Fixed Bicycle was less effective in all three dimensions. Among other interventions, Learning Bicycles, Animal-assisted therapy, and Exergaming performed better in cognitive flexibility. SPARK, Neiyang Gong, and Martial Arts were also effective in improving inhibitory control. However, SPARK and Fixed Bicycle were not significant in improving working memory.ConclusionPhysical activity as an intervention can significantly improve the executive function of children with ASD. The intervention effects of different sports on different dimensions of executive function vary. Mini Basketball was outstanding in improving inhibitory control and cognitive flexibility. Ping Pong was effective in improving cognitive flexibility and working memory. Fixed Bicycle was not effective in any dimension.

Background: To determine the association between neurological soft signs, executive functions, and serum brain-derived neurotrophic factor (BDNF) levels in children with attention-deficit hyperactivity disorder (ADHD). Methods: Serum BDNF levels were measured in 87 drug-naive boys with ADHD, aged 7–12 years. The Revised Physical and Neurological Examination for Subtle Signs for neurological soft signs, Stroop Color-Word Test for attention functions, and Judgment of Line Orientation Test (JLOT) for visuospatial abilities were performed. Results: Age correlated negatively with dysrhythmia, total time, and total overflow in timed movements, Stroop Color-Word Time (SCWT), and serum BDNF levels. The JLOT significantly negatively correlated with Total Gaits and Stations (P1) and Total Time in Timed Movements (adjusted R2 = 0.247). In addition, SCWT maintained a significant correlation with Total Overflow in Timed Movements (adjusted R2 = 0.206). There was no correlation between serum BDNF levels and NSS. Conclusion: The association between NSS, visuospatial abilities, and selective attention may express a maturational delay in ADHD pathophysiology. Moreover, BDNF may play a role in this maturational delay. Future studies should investigate the contribution of BDNF to neuronal maturation in ADHD.

Abstract Background Mild Cognitive Impairment (MCI) is a preclinical condition between healthy and pathological aging, which is characterized by impairments in executive functions (EFs), including cognitive flexibility. According to Diamond’s model, cognitive flexibility is a core executive function, along with working memory and inhibition, but it requires the development of these last EFs to reach its full potential. In this model, planning and fluid intelligence are considered higher-level EFs. Given their central role in enabling individuals to adapt their daily life behavior efficiently, the goal is to gain valuable insight into the functionality of cognitive flexibility in a preclinical form of cognitive decline. This study aims to investigate the role of cognitive flexibility and its components, set-shifting and switching, in MCI. The hypotheses are as follows: (I) healthy participants are expected to perform better than those with MCI on cognitive flexibility and higher-level EFs tasks, taking into account the mediating role of global cognitive functioning; (II) cognitive flexibility can predict performance on higher-level EFs (i.e., planning and fluid intelligence) tasks differently in healthy individuals and those diagnosed with MCI. Methods Ninety participants were selected and divided into a healthy control group (N = 45; mean age 64.1 ± 6.80; 66.6% female) and an MCI group (N = 45; mean age 65.2 ± 8.14; 40% female). Cognitive flexibility, fluid intelligence, planning, and global cognitive functioning of all participants were assessed using standardized tasks. Results Results indicated that individuals with MCI showed greater impairment in global cognitive functioning and EFs performance. Furthermore, the study confirms the predictive role of cognitive flexibility for higher EFs in individuals with MCI and only partially in healthy older adults.

The age of 5–6 years is an important stage in the development of the child’s executive functions. It is traditionally considered a sensitive period, which is complicated by the transition from the pre-school to the primary school educational system. A child’s future academic success depends on the degree of development of executive functions (EF). Identifying specific EF components that are closely related to school readiness can help devise optimal educational approaches to pre-schoolers. Early diagnosis of certain signs of control function immaturity can help correct them in order to develop all the components of voluntary attention. The purpose of this paper is to assess the development of executive functions in children aged 5–6 years. Materials and methods. The longitudinal study was conducted between 2020 and 2022 and involved 15 children (9 boys and 6 girls) aged 5 to 6 years without a history of neurological and mental diseases, attending the same preschool (in the city of Arkhangelsk) that conforms to modern educational standards. The testing was carried out at the beginning and at the end of each academic year. Results. Having compared the parameters under study in children aged 5–6 years, we found uneven development of the EF components. Progressive changes at this age concern the functions of selective regulation, control, and following certain programmes of activities. The integral indicator of the total EF deficit follows a noticeable downward trend. This can also be evidenced by significant direct correlations between the EF components and academic success.

We assessed brooding, neuroticism, suicidal ideation and attempts, and the severity of depression, anxiety, insomnia, and the Stroop tests.Results: One validated factor could be extracted from brooding, neuroticism, current suicidal behaviors, and the severity of depression, anxiety, and insomnia, labeled the phenome of depression. A large part of the variance in the phenome of depression (55.0%) was explained by the combined effects of self-, relationships, and academic-related NLEs in conjunction with ACEs, including family dysfunction and abuse and neglect (both physical and emotional). The latter ACEs significantly interacted (moderating effect) with NLEs to impact the depression phenome. Although sexual abuse did not have direct effects on the phenome, its effects were mediated by NLEs. We discovered that increased sexual abuse, physical and emotional abuse and neglect, and ACEs related to family dysfunction predicted 22.5% of the variance in NLEs. Up to 18.5% of the variance in the Stroop test scores was explained by sexual abuse and the phenome of depression. The latter mediated the effects of NLEs and abuse, neglect, and family dysfunction on the Stroop test scores.&#x00A0Conclusion: Complex intersections between ACEs and NLEs impact the phenome of depression, which comprises neuroticism, brooding, suicidal tendencies, and the severity of insomnia, anxiety, and depression, while sexual abuse together with other ACEs and NLEs may impact cognitive interference inhibition.Keywords: depression, mood disorders, affective spectrum, stress, precision psychiatry, executive functions

Abstract The adoption and maintenance of physical activity (PA) is an important health behavior. This paper presents the first comprehensive empirical test of the Physical Activity Adoption and Maintenance (PAAM) model, which proposes that a combination of explicit (e.g., intention) and implicit (e.g., habit,, affect) self-regulatory processes is involved in PA adoption and maintenance. Data were collected via online questionnaires in English, German, and Italian at two measurement points four weeks apart. The study included 422 participants (M age= 25.3, SD age= 10.1; 74.2% women) from Germany, Switzerland, Italy, Canada, and the U.S. The study results largely supported the assumptions of the PAAM model, indicating that intentions and habits significantly mediate the effects of past PA on future PA. In addition, the effect of past PA on future PA was shown to be significant through a mediation chain involving affect and habit. Although the hypothesis that trait self-regulation moderates the intention-behavior relationship was not supported, a significant moderating effect of affect on the same relationship was observed. The results suggest that interventions targeting both explicit and implicit processes may be effective in promoting PA adoption and maintenance.

AbstractThe aim of this study was to determine the effectiveness of the training package enhancement lateral domination over the components of executive functions including: initiation, working memory, planning, organizing and monitoring and visual perception components including: Visual-spatial relationship, visual form-constancy, visual sequential-memory and visual figure-ground of children with specific learning disabilities. The method of the present study was experimental with a pretest-posttest design with a control group. From elementary school children from 7 to 12 years old who were diagnosed with specific learning disabilities in psychology clinics in Tehran in 2020, 30 people were randomly selected and then randomly replaced in two groups of 15 experimental and control. The Edinburgh inventory and Delacato Neurodevelopmental Scale, TVPS-R Visual Perception Test and Brief’s Behavioral Rating Scale of Executive Functions were used to collect data. The results of the analysis of covariance showed that the training package had an effect on executive functions (p

This contribution to this Journal consists of three interlinked parts. The overarching and connecting theme is ‘Paying It Forward’, or the notion that people, children and young persons, carry out acts of kindness to strangers without expecting a return or ‘being paid’ back. After a brief elaboration on the notion of ‘paying it back’, the first part seeks to explore the phenomenon of ‘living in the now’ and how this affects this ‘paying it forward’. The second part looks at the disconnection between past, present, and future and how this impacts the manner in which young boys and girls feel about making life better for generations that come after them. This third and final section deals with ways on how to reconnect young people with their past and future and how children may grow up in a culture that embraces positive views, attitudes, and inclinations on paying it forward with future generations in mind.

Introduction: Autism Spectrum Disorders (ASDs) is a neurological disorder and can cause significant social, communication and behavioral challenges in the affected person. Aim: The purpose of this study was to compare the effectiveness of joint attention training and logotherapy on primary social communication, anxiety and executive functions of children with autism. Method: The research design was quasi-experimental with pre-test-post-test and control group. The statistical population was children with autism spectrum who referred to psychiatry and psychology centers in Urmia city in 2022. A statistical sample of 45 people was selected by a targeted method and then was randomly placed in three groups of 15 people (two experimental groups and one control group). The required data was collected using questionnaires of basic social communication (Zeboff, 2010), anxiety (Spence, 1999), executive functions (Ballister-Gerard et al., 2000) through two logotherapy intervention methods Owens and LeGoff (2007) 12 sessions of 45 minutes and through shared attention training (Vakilizad and Abedi, 2015) 12 sessions of 90 minutes and then was analyzed with SPSS version 28 software and Multivariate Analysis of Covariance Test. Results: The results showed that joint attention training and logotherapy strengthened basic social communication and executive functions and weakened anxiety in children with autism. However, there is no significant difference between the effectiveness of joint attention training and logotherapy on primary social communication, anxiety and executive functions of children with autism spectrum (P>0.01). Conclusion: Joint attention training and logotherapy lead to strengthening basic social communication and executive functions and weakening anxiety in children with autism spectrum. Therefore, these two programs can be suggested as a suitable intervention to control autistic disorders and improve the quality of life of autistic children.

Background: Due to the one-dimensionality of the existing protocols about the executive function devising task-oriented and diverse interventions grounded in executive functions and evaluating their effectiveness on the reading skills of students with attention-deficit reading disabilities is of paramount importance. Aims: This study aims to design and assess the effectiveness of a program aimed at improving reading skills, specifically focusing on executive functions, for students afflicted with attention-deficit reading disabilities. Methods: This research employs a mixed-methods approach, combining qualitative and quantitative elements. In the qualitative phase, a therapeutic intervention designed to enhance reading proficiency was developed based on a systematic review of relevant studies, with input from a panel of nine experts to ensure its validity. The subsequent quantitative phase involves a quasi-experimental design, including pre-test, post-test, and follow-up measurements with a control group. The study population consists of second and third-grade students with reading disabilities in Tehran who sought assistance from learning disability centers. Using voluntary sampling, 55 students were initially selected, and ultimately, 24 students (12 in each group) were randomly assigned based on stringent entry and exit criteria. The research instruments utilized include the Wechsler Intelligence Scale for Children, Fifth Edition, the SNSP-IV grading scale, and the reading assessment. Data analysis was conducted using repeated measures analysis of variance (ANOVA) in SPSS 25 software. Results: The mean scores on the reading assessment within the experimental group exhibited a statistically significant difference between the pre-test and post-test phases (p< 0.01). However, no significant difference was observed between the post-test and follow-up phases (p> 0.05). Conclusion: Based on the findings, it is evident that the developed program can effectively enhance the reading proficiency of students grappling with attention-deficit reading disabilities.

Replicated evidence shows a weak or non-significant correlation between different methods of evaluating executive functions (EF). The current study investigates the association between rating scales and cognitive tests of EF in a sample of children with ADHD and executive dysfunction.

Background: It is important to address individual and interpersonal factors involved in behavioral problems to prevent their serious consequences. This study investigated the mediating role of executive functions in the correlation between intelligence and student-teacher relationship with behavioral problems.Methods: This was a cross-sectional study with a descriptive-correlational approach. The statistical population included the students of the first grade to third grade in Bojnord, Iran. Using the cluster sampling method, two elementary schools (first period) were selected for data collection from February 2023 to April 2023. The study participants were 351 students aged 6 to 10 years old. The parents completed the Child Behaviour Checklist (CBCL/6–18), and Behavioral rating inventory of executive functions (BRIEF). The teachers completed the Student-Teacher Relationship Scale (STRS) for each student, and the students were tested individually by the Colored Progressive Matrices Test (CPMT). The data were analyzed using PLS version 4 and SPSS version 22 by correlation test and structural equation model.Results: The findings showed that executive functions have a significant impact on behavioral problems (β=0.43, P

Abstract Background Substance use disorder (SUD) is associated with executive function (EF) deficits and sensory modulation dysfunction (SMD). Yet, these deficits are not addressed therapeutically. This study aims to examine the effectiveness of the Functional-Cognitive and Sensory Treatment (F-CaST) compared to standard care to improve everyday performance and behavior and length of stay at the therapeutic community (TC) in individuals with SUD. In addition, to assess the improvement in EF, sensory modulation, participation, self-efficacy, life satisfaction, and use of strategies within and between groups. Satisfaction with F-CaST will also be assessed. Methods Forty-eight participants from a community of men in a TC, aged 18–45 years will be randomly allocated to (i) F-CaST—(experimental group) providing sensory and EF strategies for improving daily function; (ii) standard care (control group) as provided in the TC. Assessments will be conducted by assessors blind to group allocation at 4 time points: T1- pre-intervention; T2- post-intervention; T3- 1-month follow-up; and T4- 3-month follow-up. Primary outcome measures will be everyday performance, assessed by the Canadian Occupational Performance Measure (COPM), behavior and length of stay in the TC; secondary outcome measures will assess EF, SMD. Semi-structured in-depth qualitative interviews will be conducted at T1, T2 and T4. Discussion We hypothesize that F-CaST will lead to improved everyday performance and longer length of stay in the TC, compared to the control group. If F-CaST will prove to be effective, cognitive and sensory strategies may be incorporated as an adjunctive intervention in SUD rehabilitation.

Abstract Background The optimal stimulation for brain development in the early academic years remains unclear. Current research suggests that musical training has a more profound impact on children's executive functions (EF) compared to other art forms. What is crucially lacking is a large-scale, long-term genuine randomized controlled trial (RCT) in cognitive neuroscience, comparing musical instrumental training (MIP) to another art form, and a control group (CG). This study aims to fill this gap by using machine learning to develop a multivariate model that tracks the interconnected brain and EF development during the academic years, with or without music or other art training. Methods The study plans to enroll 150 children aged 6-8 years and randomly assign them to three groups: Orchestra in Class (OC), Visual Arts (VA), and a control group (CG). Anticipating a 30% attrition rate, each group aims to retain at least 35 participants. The research consists of three analytical stages: 1) baseline analysis correlating EF, brain data, age, gender, and socioeconomic status, 2) comparison between groups and over time of EF brain and behavioral development and their interactions, including hypothesis testing, and 3) exploratory analysis combining behavioral and brain data. The intervention includes intensive art classes once a week, and incremental home training over two years, with the CG receiving six annual cultural outings. Discussion This study examines the potential benefits of intensive group arts education, especially contrasting music with visual arts, on EF development in children. It will investigate how artistic enrichment potentially influences the presumed typical transition from a more unified to a more multifaceted EF structure around age eight, comparing these findings against a minimally enriched active control group. This research could significantly influence the incorporation of intensive art interventions in standard curricula. Trial registration The project was accepted after peer-review by the Swiss National Science Foundation (SNSF no. 100014_214977) on March 29, 2023. The study protocol received approval from the Cantonal Commission for Ethics in Human Research of Geneva (CCER, BASEC-ID 2023-01016), which is part of Swiss ethics, on October 25, 2023. The study is registered at clinicaltrials.gov (NCT05912270).

Abstract Background Executive functions (EFs) and episodic memory are fundamental components of cognition that deteriorate with age and are crucial for independent living. While numerous reviews have explored the effect of exercise on these components in old age, these reviews screened and analyzed selected older adult populations, or specific exercise modes, thus providing only limited answers to the fundamental question on the effect of exercise on cognition in old age. This article describes the protocol for a systematic review and multilevel meta-analytic study aiming at evaluating the effectiveness of different types of chronic exercise in improving and/or maintaining EFs and long-term episodic memory in older adults. Methods and analysis The study protocol was written in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Several databases will be searched. Randomized controlled trials (RCTs) conducted in older adults aged ≥ 60 years providing any kind of planned, structured, and repetitive exercise interventions, and EFs and/or episodic memory measures as outcomes, published in English in peer-reviewed journals and doctoral dissertations will be included. Two independent reviewers will screen the selected articles, while a third reviewer will resolve possible conflicts. The Cochrane risk-of-bias tool will be used to assess the quality of the studies. Finally, data will be extracted from the selected articles, and the formal method of combining individual data from the selected studies will be applied using a random effect multilevel meta-analysis. The data analysis will be conducted with the metafor package in R. Discussion and conclusion This review will synthesize the existing evidence and pinpoint gaps existing in the literature on the effects of exercise on EFs and episodic memory in healthy and unhealthy older adults. Findings from this meta-analysis will help to design effective exercise interventions for older adults to improve and/or maintain EFs and episodic memory. Its results will be useful for many researchers and professionals working with older adults and their families. Systematic review registration PROSPERO CRD42022367111.

AbstractThe purpose of this study was to determine the effective of the training program of executive functions on improving levels of theory of mind in children with attention deficit / hyperactivity disorder. The research method was semi-experimental with post-test pre-test with control group. The study population included all 6- to 8-year-old children in Tabriz, of whom 30 were selected by convenience sampling and randomly assigned to experimental (15) and control (15) groups.Then the Theory of Mind Questionnaire (Hutchins, Perlock , Bonazinga , 2012) was completed by parents of both groups. After performing the pre-test, the experimental group was trained in the executive functions program. The program was designed by researchers and consisted of 24 sessions in which 4 skills (working memory, inhibition, flexibility and attention training) were taught, At this stage, the children in the control group did not receive any training. The post-test was performed again and the data obtained from the pre-test and post-test were analyzed using analysis of covariance.The data showed a significant difference between the control and experimental groups in the post-test of variable theory of mind scores after adjusting for the effect of pre-test of theory of mind(P
