Abstract
Sleep has been shown to have an impact on the consolidation of motor memory in adults. However, sleep-dependent consolidation is not well-specified among children compared with adults. Therefore, the purpose of this study was to investigate the effect of sleep on children's motor memory consolidation. The participants were 32 voluntary boys aging from 10 to 12 years old from Kerman, which had the necessary qualifications for entering the study. Serial Reaction Time Task was used to determine the implicit memory in children. The participants were allocated into a sleep group (8±1pm and 8±1am) and a wake group (8±1am and 8±1pm). Each group underwent five training blocks consisiting of 90 trails in each block in the acquisition phase. The retention (consolidation) and transfer tests were administered 12 hours after the acquisition phase in both groups. For analyzing data 2×2 and 4×2 Mixed ANOVA tests were used. The results in the retention and transfer tests showed that the reaction time was significantly different in two blocks (P > 0.05), but the effect of group and block interaction was not significant (P ≥ 0.05). The results also indicated that motor memory consolidation occurred in sleep and wake groups, however, it was not sleep-dependent. The findings revealed that children‘s performance was improved and enhanced not only through the training sessions, but after the learning phase in the offline period. In addition, the memory associated with a learned skill enhanced over time. It can be concluded that sleep was not the essential factor in the enhancement of offline learning and the transfer of sequential implicit motor task among children.

Abstract
The current research aims to examine the structural relationships between sleep problems and emotional intelligence in adolescents, considering the mediating role of defect in executive functions. The present research had a descriptive-correlational design. The study sample included 381 first-grade high school students in Tabriz during the academic year 1401-02, selected through cluster random sampling. Data were collected using the Pittsburgh Sleep Quality Index questionnaire, the Siberia and Shiring Emotional Intelligence Questionnaire, the Gross and John Emotion Regulation Questionnaire, the Wisconsin Card Sorting Test software, and the Continuous Performance Test software task. Statistical methods used for data analysis included Pearson correlation coefficient and path analysis. The results showed that sleep problems have a direct and indirect influence on emotional intelligence through emotion regulation and cognitive flexibility. Based on the research findings, it can be concluded that emotion regulation and cognitive flexibility play a mediating role in the relationship between sleep problems and emotional intelligence.

Abstract
This research was conducted with the aim of providing a structural model of the effect of sleep disorders on learning problems with the mediating role of cognitive flexibility in children. This research was a descriptive-correlation study. The statistical population of the research included all primary school students (ages 9 to 12 years) in district 3 of Marand city in 2023. From this society, 300 students were selected by staged cluster sampling method. Data collection tools included Children's Sleep Habits Questionnaire (CSHQ), Colorado Learning Difficulties Questionnaire (CLDQ) and Wisconsin Card Sorting Test (WCST). Data analysis was done using Pearson correlation in spss version 26 and structural equation analysis in AMOS version 21. Data analysis showed that children's sleep disorders have a direct and positive effect on cognitive flexibility and learning problems, and cognitive flexibility also has a direct and positive effect on learning problems, which were statistically significant. Also, children's sleep disorders had a significant indirect effect on learning problems through cognitive flexibility in a positive way. These results mean the importance of maintaining and improving the quality of children's sleep to support the learning process and improve their cognitive performance. Therefore, paying attention to healthy sleeping habits and creating a suitable sleeping environment for children can be effective in increasing cognitive flexibility and reducing their learning problems.
