J Dehghanizadeh, H. Mohammadzadeh, F. S. Hosseini,
Volume 1, Issue 1 (12-2013)
Abstract

 
The aim of this study was to investigate the effects of gymnastics training, as a motor activity, on the mental rotation. This Study was carried out considering an experimental group, students of physical education practicing gymnastics training, and a control group, students of the other majors of the faculty of humanities in each group there were 40 students, 20 males and 20 females. First, the two groups took the mental rotation test of Peters et al (1995), and then the experimental group has undergone gymnastics training for 9 weeks. After the training sessions, both groups were tested again. To examine the differences in pre-test and post-test scores of the two groups, one way analysis of covariance was used, and to examine the differences of mental rotation between the two groups in pre-test scores, T test was used. The findings showed significant difference in the scores of the post- test compared to those of the pre-test, and it was shown in the experimental group. The difference between the scores of the students of physical education and the scores of the students of other majors of the faculty of humanities was significant to the benefit of the students of physical education. Furthermore, between the scores of the girls and boys in the mental rotation, significant difference was observed to the benefit of boys. In the present study, the effect of the gymnastics training program on the ability of mental rotation was concluded and this conclusion showed the effects of the program of motor intervention on the spatial and cognitive abilities

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.

Abstract
This study examined the prediction of addiction tendency based on differentiation of self, self-construal, and coping styles. The primary aim was to identify the psychological factors significantly predicting addiction tendency and to analyze the relationships among these variables. The statistical population included all undergraduate students at Payame Noor University of Qom in 2021. Using simple random sampling, 285 students from various faculties were selected as the sample. Data were collected using standardized questionnaires, including the Addiction Tendency Scale, Differentiation of Self Inventory, Self-Construal Scale, and Coping Styles Inventory. Pearson correlation and multiple regression analysis were applied to analyze the data.The results indicated that differentiation of self, self-construal, and coping styles significantly predicted addiction tendency. Among these variables, coping styles had the highest predictive coefficient (β = 0.50), followed by differentiation of self (β = 0.45) and self-construal (β = 0.32). The findings revealed that individuals with lower differentiation of self and less effective coping styles are more likely to exhibit addiction tendencies.This study highlights the crucial role of psychological factors in understanding addiction tendencies and has significant implications for designing preventive and therapeutic interventions. The findings can serve as a scientific basis for promoting mental health and reducing high-risk behaviors, including addiction.
