Abstract
Objective: Working memory executive deficits have a role in maintaining Post-Traumatic Stress Disorder (PTSD) symptoms including flashbacks and reexperiencing. Accordingly, the aim of the present study was to compare the visual and verbal Proactive Interference in trauma-exposed individuals with and without PTSD.
Method: In this retrospective study, we recruited subjects through the purposive sampling method. We compared 30 survivors of road traffic accidents with PTSD with 30 trauma-exposed individuals without PTSD in terms of visual and verbal Proactive Interference. Measuring tools included the Post-Traumatic Stress Disorder semi-structured Interview for DSM-V, the Beck Depression Inventory-II and the Recent Probes Task. Data were analyzed using mixed repeated-measures analysis of variance (ANOVA) in SPSS-21 software.
Results: Subjects of the PTSD group reported higher levels of visual and verbal Proactive Interference than the control group. Moreover, patients with PTSD indicated higher deficiencies in visual working memory than verbal working memory.
Conclusion: Patients with PTSD show deficiencies in controlling proactive interference that should be taken into consideration through their treatment procedure.

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.
