The normative, developmental changes in affect-biased attention during the preschool years are largely unknown. To investigate the attention bias for emotional versus neutral faces, an eye-tracking measurement and free viewing of paired pictures of facial expressions (i.e., happy, fearful, sad, or angry faces) and nonface pictures with neutral faces were conducted with 367 children participating in a Finnish cohort study at the age of 2.5 years and with 477 children at the age of 5 years, 216 of which having follow-up measurements. We found an attention-orienting bias for happy and fearful faces versus neutral faces at both age points. An attention-orienting bias for sad faces emerged between 2.5 and 5 years. In addition, there were significant biases in sustained attention toward happy, fearful, sad, and angry faces versus neutral faces, with a bias in sustained attention for fearful faces being the strongest. All biases in sustained attention increased between 2.5 and 5 years of age. Moderate correlations in saccadic latencies were found between 2.5 and 5 years. In conclusion, attention biases for emotional facial expressions seem to be age-specific and specific for the attentional subcomponent. This implies that future studies on affect-biased attention during the preschool years should use small age ranges and cover multiple subcomponents of attention.

Most infants exhibit an attentional bias for faces and fearful facial expressions. These biases reduce toward the third year of life, but little is known about the development of the biases beyond early childhood. We used the same methodology longitudinally to assess attention disengagement patterns from nonface control pictures and faces (neutral, happy, and fearful expressions) in a large sample of children at 8, 30, and 60 months (N = 389/393/492, respectively; N = 72 for data in all three assessment; girls >45.3% in each assessment). "Face bias" was measured as a difference in disengagement probability (DP) from faces (neutral/happy) versus nonface patterns. "Fear bias" was calculated as a difference in DP for fearful versus happy/neutral faces. At group level, DPs followed a nonlinear longitudinal trajectory in all face conditions, being lowest at 8 months, highest at 30 months, and intermediate at 60 months. Face bias declined between 8 and 30 months, but did not change between 30 and 60 months. Fear bias declined linearly from 8 to 60 months. Individual differences in disengagement were generally not stable across age, but weak correlations were found in face bias between 8- and 60-month, and in DPs between 30- and 60-month (rs = 0.22-0.41). The results suggest that prioritized attention to faces--that is, a hallmark of infant cognition and a key aspect of human social behavior--follows a nonlinear trajectory in early childhood and may have only weak continuity from infancy to mid childhood.

High levels of early emotionality (of either negative or positive valence) are hypothesized to be important precursors to early psychopathology, with attention-deficit/hyperactivity disorder (ADHD) a prime early target. The positive and negative affect domains are prime examples of Research Domain Criteria (RDoC) concepts that may enrich a multilevel mechanistic map of psychopathology risk. Utilizing both variable-centered and person-centered approaches, the current study examined whether levels and trajectories of infant negative and positive emotionality, considered either in isolation or together, predicted children's ADHD symptoms at 4 to 8 years of age. In variable-centered analyses, higher levels of infant negative affect (at as early as 3 months of age) were associated with childhood ADHD symptoms. Findings for positive affect failed to reach statistical threshold. Results from person-centered trajectory analyses suggest that additional information is gained by simultaneously considering the trajectories of positive and negative emotionality. Specifically, only when exhibiting moderate, stable or low levels of positive affect did negative affect and its trajectory relate to child ADHD symptoms. These findings add to a growing literature that suggests that infant negative emotionality is a promising early life marker of future ADHD risk and suggest secondarily that moderation by positive affectivity warrants more consideration.

BackgroundEarly life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life.MethodsIn two independent prospective cohorts in Turku, Finland (N = 135), and Irvine, CA, USA (N = 192) that differed significantly in race/ethnicity and sociodemographic parameters, we assessed whether infant exposure to unpredictable patterns of maternal-derived sensory signals portended poor effortful control.OutcomesIn both the Irvine and Turku cohorts, unpredictable sequences of maternal behavior during infancy were associated with worse effortful control at one year of age. Longitudinal analyses demonstrated that this association persisted for as long as each cohort was assessed-until two years of age in the Turku cohort and to 9.5 years in the Irvine cohort. The relation of unpredictable maternal signals during infancy and the measures of executive function persisted after adjusting for covariates.InterpretationsThe consistency of our findings across two cohorts from different demographic backgrounds substantiated the finding that patterns, and specifically unpredictable sequences, of maternal behaviors may influence the development of executive functions which may be associated with vulnerability to subsequent psychopathology.

Objective: Early psychosocial interventions for preterm infants and their parents are diverse. This study aimed to structure the knowledge on psychosocial parent-infant interventions and to identify gaps in the intervention studies. Methods: We included studies on early (during first year of life) psychosocial parent-infant interventions with parent-infant relationship outcomes after preterm birth (< 37 weeks). We excluded studies that did not focus on preterm infants, failed to indicate the studied intervention and outcomes, were not written in English, were not controlled or peer-reviewed studies, or did not provide essential information for eligibility. The search included studies published between January 2000 and March 2024 in PubMed and PsycINFO. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in reporting. Psychosocial parent-infant intervention studies were classified adapting the International Classification of Health Interventions (ICHI) and the Template for Intervention Description and Replication (TIDieR). Results: The included 22 studies reported data from 18 different interventions with preterm infants (< 37 weeks). Studies excluded preterm infants with health risks (19/22, 86%), with very low gestational age and/or birth weight (7/22, 32%), and/or mothers with psychosocial risks (14/22, 64%). Of the 18 interventions, 12 (67%) were classified as counseling, 3 (17%) as emotional support, 2 (11%) as psychotherapeutic, and 1 (6%) as educational. The parent-child relationship was assessed using 30 different methods and varying time points up to 18 months of age. Most studies (17/22, 77%) reported positive changes in the parent-child relationship favoring the intervention group. Conclusion: We identified four types of interventions to influence parenting behavior; the most used was counseling. All four intervention types showed positive effects on parent-infant relationships, although the preterm populations studied were selective, the effects were evaluated using different methods, and the follow-up periods were short. These findings indicate a need for studies with standardized methods, longer follow-up, and less-restricted preterm populations to develop guidelines for all families with preterm infants.

Parental representations of the child are linked to positive developmental outcomes in children, but the impact of prenatal representations on early social-emotional development, particularly from fathers, is less understood. This study explores how fathers' and mothers' prenatal representations within two-parent families are associated with early social-emotional development. Prenatal representations of fathers (n = 88) and mothers (n = 92) were assessed between 28 and 32 weeks of gestation using the Working Model of the Child Interview, categorizing them as balanced or nonbalanced. The children's (n = 97; 49.5% girls) social-emotional and behavioral problems and competencies were measured at 18 months using the Brief Infant-Toddler Social and Emotional Assessment. Balanced prenatal representations of both parents were related to higher social-emotional competence in toddlers. However, prenatal representations were not related to social-emotional and behavioral problems. The results highlight the benefits of balanced prenatal representations in promoting early social-emotional competence in children. [ABSTRACT FROM AUTHOR]

This study tested whether executive functioning (EF)/learning tasks from the CogState computerized test battery show a unitary latent structure. This information is important for the construction of composite measures on these tasks for applied research purposes. Based on earlier factor analytic research, we identified five CogState tasks that have been labeled as EF/learning tasks and examined their intercorrelations in a new sample of Finnish birth cohort mothers (N = 233). Using confirmatory factor analyses, we compared two single-factor EF/learning models. The first model included the recommended summative scores for each task. The second model exchanged summative scores for first test round results for the three tasks providing these data, as initial task performance is expected to load more heavily on EF. A single-factor solution provided a good fit for the present five EF/learning tasks. The second model, which was hypothesized to tap more onto EF, had slightly better fit indices, X[superscript 2](5) = 1.37, p = 0.93, standardized root mean square residual (SRMR) = 0.02, root mean square error of approximation (RMSEA) = 0.00, 90% CI = [0.00-0.03], comparative fit index (CFI) = 1.00, and more even factor loadings (0.30-0.56) than the first model, X[superscript 2](5) = 4.56, p = 0.47, SRMR = 0.03, RMSEA = 0.00, 90% CI = [0.00-0.09], CFI = 1.00, factor loadings (0.20-0.74), which was hypothesized to tap more onto learning. We conclude that the present CogState sum scores can be used for studying EF/learning in healthy adult samples, but call for further research to validate these sum scores against other EF tests.

Research has revealed a rise in family relationship problems during the COVID-19 pandemic, especially among couples with young children. However, longitudinal studies spanning the prepandemic and pandemic periods are rare. In this study, we examined changes in couple functioning during these periods. Moreover, we investigated the mediation and moderation effects of couple functioning on the association between COVID-19 stressors and harsh parenting. A total of 545 mothers (mean age 38 years, range 23–48 years) completed questionnaires on couple functioning during the prepandemic (2016–2020) and early pandemic (May–June 2020) periods. During the early pandemic, they also reported exposure to COVID-19 stressors and engaging in harsh parenting (e.g., conflicts and maltreatment). We found no overall deterioration in couple functioning during the early pandemic. Furthermore, COVID-19 stressors did not explain variance in couple functioning changes or correlate with harsh parenting. However, as hypothesized, couple functioning moderated the effect of COVID-19 stressors on harsh parenting. Only for couples with low prepandemic functioning was exposure to COVID-19 stressors associated with harsh parenting. In conclusion, our findings provided no evidence of COVID-19's detrimental effects on couples during the early pandemic. Instead, well-functioning couple relationships appear to mitigate the impact of pandemic stressors on parenting. [ABSTRACT FROM AUTHOR]

Parental executive functioning (EF) is considered one key contributing source, via direct and indirect routes, of inter-individual variation in offspring EF. The current study investigated the unexplored associations between maternal EF and infant EF as well as its precursor, sustained attention. Ninety-seven mother-infant-dyads from the FinnBrain Birth Cohort Study participated. Maternal EF was assessed using selected measures from the Cogstate test battery. At 8 months, infants completed Lab-TAB Blocks and modified A-not-B tasks. A modest but robust link between maternal EF and infant attention was revealed in girls. There was no association between mother and infant EF in either sex at 8 months. Notable directions for future research, and potential underlying mechanisms of sex differences are discussed.

Research on the longitudinal courses of child social–emotional symptoms and sleep during the COVID-19 pandemic within societies would be of key value for promoting child well-being in global crises. We characterized the course of children's social–emotional and sleep symptoms before and throughout the pandemic in a Finnish longitudinal cohort of 1825 5- to 9-year-old children (46% girls) with four follow-up points during the pandemic from up to 695 participants (spring 2020–summer 2021). Second, we examined the role of parental distress and COVID-related stressful events in child symptoms. Child total and behavioral symptoms increased in spring 2020 but decreased thereafter and remained stable throughout the rest of the follow-up. Sleep symptoms decreased in spring 2020 and remained stable thereafter. Parental distress was linked with higher child social–emotional and sleep symptoms. The cross-sectional associations between COVID-related stressors and child symptoms were partially mediated by parental distress. The findings propose that children can be protected from the long-term adverse influences of the pandemic, and parental well-being likely plays a mediating role between pandemic-related stressors and child well-being. Further research focusing on the societal and resilience factors underlying family and child responses to the pandemic is warranted. [ABSTRACT FROM AUTHOR]

This study examined longitudinal associations between parental psychological distress (stress and depression) when the child was 2 to 4 years and a child's emotional and behavioural problems at ages 3 to 4, and social functioning (loneliness and social competence) at age 11 in very preterm born children. The participants were Finnish families of 172 very preterm infants (gestational age < 32 weeks and/or birth weight ≤ 1500 g). In girls, higher levels of maternal depression were associated with higher levels of social and emotional loneliness. Furthermore, higher levels of maternal stress and children's externalizing problems were associated with lower levels of experienced empathy. In boys, higher levels of paternal depression were associated with lower levels of social loneliness and impulsive behaviour. In conclusion, early parental psychological distress is associated with early socioemotional development and the later experienced social functioning in former very preterm infants. The sex of the child moderates these associations. [ABSTRACT FROM AUTHOR]

Aim: To investigate how the aetiology of very preterm birth/very low birth weight is associated with mortality and later neurodevelopmental outcomes. Methods: Very preterm/very low‐birth weight singletons were categorised based on the aetiology of preterm birth: spontaneous preterm birth (n = 47, 28.1%), preterm premature rupture of membranes (n = 56, 33.5%) or placental vascular pathology (n = 64, 38.3%). Mortality, cerebral palsy, severe cognitive impairment by 11 years of age (<2SD) and mean full‐scale intelligence quotient at 11 years were studied in association with birth aetiology. Results: There was no difference in mortality or rate of cerebral palsy according to birth aetiologies. The rate of severe cognitive impairment was lower (4.9% vs. 15.3%) in the preterm premature rupture of the membrane group in comparison to the placental vascular pathology group (OR 0.2, 95% CI 0.03–0.9, adjusted for gestational age). At 11 years, there was no statistically significant difference in the mean full‐scale intelligence quotient. Conclusion: Placental vascular pathology, as the aetiology of very preterm birth/very low birth weight, is associated with a higher rate of severe cognitive impairments in comparison to preterm premature rupture of membranes, although there was no difference in the mean full‐scale intelligence quotient at 11 years. The aetiology of very preterm birth/very low birth weight was not associated with mortality or the rate of cerebral palsy. [ABSTRACT FROM AUTHOR]

Toddlerhood is a period of intensive and rapid socio-emotional development. The effects of different types of childcare settings on child development have been widely studied, but the results have often been contradictory. The aim of this study was to compare social competence and socio-emotional problems in two-year-old children (n = 1104; girls 47.2%) who were either participating in out-of-home, center-based childcare or were cared for at home by their parents in Finland. The results showed that mothers reported more internalizing symptoms in toddlers participating in out-of-home, center-based childcare when compared to children who were cared for at home. No differences regarding externalizing symptoms or social competence were found. Overall, the results suggest that out-of-home, center-based childcare is not associated with major differences in a toddler's socio-emotional development. More research is needed to investigate whether differences in the socio-emotional development of the children participating in different types of childcare develop later in childhood.
