Autism spectrum disorders (ASD) are associated with cognitive dysfunctions, including mental time travel (MTT). However, findings on diminished MTT ability may be confounded by a number of factors, including the individuals' language ability, factors related to the MTT task and the demographic factors of participants. The present study provided a meta-analysis of MTT ability in people with ASD. The results showed significant overall reductions in MTT ability in people with ASD. Moderator analyses revealed that the variables examined did not explain the reduction in MTT ability. These findings suggest that MTT ability is diminished in people with ASD and that the degree of this diminishment may not depend on the characteristics of measures or demographic variables of people with ASD.

Negative association was found between the frontal theta/beta ratio and mind wandering in participants with high schizotypal traits, while no such association was found in participants with low schizotypal traits. These findings provide insights into the neural mechanism of mind wandering in individuals with high schizotypal traits. [ABSTRACT FROM AUTHOR]

The present study aimed to examine social attribution in children with high-functioning autism (HFA) and Asperger's syndrome (AS). A sample of 20 boys (9 with HFA and 11 with AS) and 20 age-matched controls were recruited for this study. All participated in two tasks measuring social attribution ability, the conventional Social Attribution Task (SAT) and a modified version with animals rather than shapes (mSAT). They also completed a battery of neuropsychological tests. Compared to typically developing controls, children with autism spectrum disorders were impaired on some measures in both SATs. However, group differences in "theory-of-mind" indices were only significant in the mSAT, with the ASD group performing more poorly than controls. In addition, the scores in person index of both versions of the SAT correlated with executive function in children with HFA/AS. The current study found the mSAT paradigm was especially sensitive to ToM difficulties in young Chinese children with HFA/AS. Social attribution in children with HFA/AS, unlike neurotypical children, was related to executive function ability, suggesting these psychological domains are not distinct in children with autism spectrum disorders.

Delay discounting (DD) refers to the phenomenon in which the subjective value of future rewards is reduced over time. There are individual differences in the DD rate, and increased discounting has been observed in those with various psychiatric disorders. Episodic future thinking (EFT) is the act of vividly imagining events that may happen in the future. Studies have shown that EFT could reduce DD, although inconsistent results have been reported. The aim of this meta-analysis was to clarify the efficacy with which EFT reduces DD and to identify potential moderators. Forty-seven studies (including 63 contrasts) were included in the final analysis. EFT was found to significantly reduce DD (Hedges' g = 0.52). Moderator analysis showed that positive EFT (g = 0.64) was more effective in reducing DD than EFT with the valence not specifically mentioned (g = 0.28) and EFT with neutral or negative valence (g = –0.03). In addition, several factors related to the control task and DD task were related to the efficacy of EFT to reduce DD. These findings have implications for using EFT to reduce DD in the future.

Schizotypal traits have been found to be negatively associated with satisfaction with life but the underlying mechanisms are not well understood. This study investigated the association between schizotypal traits and satisfaction with life and explored the mediating role of trait anxiety and mind wandering in the relationship between those two variables in a sample of Chinese young adults. One hundred and two individuals with high schizotypal traits and 104 individuals with low schizotypal traits were screened using the Schizotypal Personality Questionnaire. They completed a series of questionnaires including the Satisfaction with Life Scale, Trait Anxiety Inventory, and Mind Wandering Questionnaire. Results showed that: First, the high schizotypal trait group showed lower satisfaction with life, and higher trait anxiety and mind wandering frequency than the low schizotypal trait group. Second, the high schizotypal trait group, trait anxiety, and mind wandering negatively predicted satisfaction with life. Third, mediation analyses showed that all indirect effect paths in the mediation model were significant, that is, trait anxiety and mind wandering alone and together mediated the relationship between schizotypal trait group and satisfaction with life. In conclusion, high schizotypal trait is a risk factor for low satisfaction with life. The association between schizotypal traits and satisfaction with life was mediated by the combination of trait anxiety and mind wandering. This study has implications for improving life satisfaction in individuals with high schizotypal traits. [ABSTRACT FROM AUTHOR]

Involuntary mental time travel (MTT) refers to the phenomenon of mentally reliving past experiences or pre‐living possible future events in an involuntary form. Few studies have explored involuntary MTT in individuals with schizotypal personality features. The present study aimed to first explore the psychometric properties of the Involuntary Autobiographic Memory Inventory (IAMI) in a Chinese sample (Study 1), and then to explore whether individuals with schizotypal personality features experience involuntary MTT more frequently than individuals without schizotypal features. Moreover, the study explored whether the aberrant frequency of involuntary MTT is correlated with positive schizotypal features (Study 2). The results showed that the IAMI had good structural validity and reliability in a Chinese sample. Individuals with schizotypal traits reported a significantly higher frequency, less positive emotion, and stronger emotional intensity for both involuntary memories and future thoughts compared with individuals without schizotypal features. Further analyses in individuals with schizotypal personality features showed that the frequencies of both involuntary memories and future thoughts were significantly correlated with positive schizotypal traits. These results have potential theoretical and clinical implications for a comprehensive understanding of involuntary MTT among individuals with schizotypal personality features. [ABSTRACT FROM AUTHOR]
