Since working memory capacity (WMC) predicts individual differences in the wide range of abilities, this experiment tested the effect of WMC on time perception in preschool children.
At first, 108 children’s working memory capacity were measured by CANTAB tests and then 21 children with high working memory capacity and 20 children with low working memory capacity were assigned. Then, both groups performed two reproduction tasks they instructed to reproduce 700 and 3000 millisecond intervals in mono task, and to reproduce 3000 ms with a performing concurrent non-temporal task as a dual task. Data analyzed by mixed design ANOVA and post hoc tests. Results showed that in mono task, accuracy of high WMC was better than the low WMC group. In dual task, although there was no significant difference in the accuracy of reproduction task, children with high WMC had better performance in non-temporal task. Furthermore, children with low WMC were more variable performance than high WMC in all intervals.
 

The present study aimed to investigate the mediating role of cognitive self-efficacy in the relationship between early maladaptive schemas and psychological vitality in individuals with generalized anxiety disorder. The statistical population consisted of all clinical medical students at Golestan University in 2024, from which a sample of 120 students was selected through non-random convenience sampling. The research instruments included the Young Schema Questionnaire – Short Form (1998), the Cognitive Self-Efficacy Scale by Sherer et al. (1982), and the Psychological Vitality Scale developed by Kahn and Crawford (2003). Data were analyzed using structural equation modeling (SEM). The results indicated that early maladaptive schemas had a significant negative relationship with psychological vitality, and this relationship was mediated by reduced cognitive self-efficacy. In other words, early maladaptive schemas lead to decreased psychological vitality in individuals with generalized anxiety disorder by weakening cognitive self-efficacy. These findings highlight the importance of addressing early maladaptive schemas and enhancing cognitive self-efficacy as therapeutic strategies to improve psychological vitality and overall mental well-being in individuals suffering from anxiety. Accordingly, it is recommended that psychological interventions simultaneously target schema modification and self-efficacy enhancement.
