Asoodeh Roozmehr, Alireza Moradi, Hadi Parhoon, Yazdan Naderi,
Volume 2, Issue 1 (6-2014)
Abstract

The objective of the current research is to compare the function of declarative memory among war veterans who are suffering from PTSD ,war veterans who are not suffering from PTSD and normal people without any war experience the research has also aimed at studying and comparing the influence of the modifying role of meta cognition on the function of declarative memory among the three groups of the study.60 people have been selected and placed in three groups: 20 war veterans suffering from PTSD , chosen by PTSD scales 20 veterans not suffering from PTSD and 20 normal people without any war experience. All three groups were evaluated by WatsonPTSD questionnaires, declarative memory memory interview and delayed recall story) and meta cognition questionnaire .The research hypotheses were tested by multivariate analysis of covariance (MANCOVA). The result have indicated that the function of declarative memory in the three groups without the control of meta cognition moderator is significant , in another word the declarative memory function in war veterans suffering from PTSD is different with the two other groups. It can be also deduced from the results of the research that the declarative memory function by the control of meta cognition modifying  role was not significant this time which indicates the modifying role of meta cognition in decreasing the declarative memory function in war veterans suffering from PTSD in comparison with the two other mentioned groups.

Abstract
The aim of this study was to investigate the effect of Cognitive rehabilitation traning (CTR) on Executive functions and attention in students with lrarning problem. In an experimental study with pre-test, post-test and control group, 42 students with LP were selected through convenient sampling method. They were randomly assigned to the experimental and control groups. The experimental group underwent two months’of intervention and the scores of the Behavior Rating Inventory of Executive Functions (BRIEF), and the Stroop Color and Word Test (SCWT) were gathered in both groups before and after the intervention and in one month follow up. The data was analyzing by the statistical test of mixed variance analysis. The results in the post-test and follow-up stages showed that there is a significant difference between the two experimental and control groups, in terms executive functions, and attention. This means that the experimental group who underwent the intervention program had significant improvement in the post-test phase in terms of executive functioning and attention. the changes made during the follow-up phase remained consistent. Also, based on the results obtained, cognitive rehabilitation intervention did not significantly affect the emotional regulation index of students with the LP. The results of this study indicate the effectiveness of a designed cognitive rehabilitation program on executive function, and attention of students with LP; therefore, considering these findings and the mechanism, the effectiveness of this intervention method can have appropriate therapeutic effects on reducing cognitive and psychological problems and improving the quality of life of student with LP.

The Relationship between Inhibitory Control, Cognitive Flexibility, and Perceived Organizational Support with Teachers’ Job Burnout: The Mediating Role of Self-Efficacy

Abstract
Abstract
The present study was conducted to examine the mediating role of self-efficacy in the relationship between inhibitory control, cognitive flexibility, and perceived organizational support and teachers’ job burnout.. Within the framework of the post-positivist paradigm, a quantitative approach was employed using a correlational design based on structural equation modeling.
A total of 370 teachers working in schools in Kermanshah during the 1403–1404 academic year were selected through convenience sampling. The following instruments were used for data collection: the Executive Functioning Scale (Holst & Thorell, 2018), the Cognitive Flexibility Scale (Dennis & Vander Wal, 2010), the Perceived Organizational Support Questionnaire (Eisenberger et al., 1986), the Teacher Self-Efficacy Scale (Schannen-Moran & Woolfolk Hoy, 2001), and the Teacher Burnout Scale (Chang et al., 2020).Data were analyzed using SPSS 27 and SmartPLS 4 within the framework of structural equation modeling. The results indicated that the research model had a good fit with the data.
The findings revealed that inhibition control had a direct and significant effect on teacher burnout (β = -0.377, t = 3.264, p = 0.001) and on self-efficacy (β = 0.271, t = 3.750, p < 0.001). Cognitive flexibility influenced teacher burnout (β = -0.200, t = 3.064, p < 0.002) and self-efficacy (β = 0.244, t = 3.264, p < 0.001). Perceived organizational support affected teacher burnout (β = -0.273, t = 2.339, p = 0.020) and self-efficacy (β = 0.215, t = 2.887, p < 0.001). Self-efficacy had a direct effect on teacher burnout (β = -0.64, t = 4.96, p < 0.001; β = 0.616, t = 6.015, p < 0.001).
These results suggest that part of the predictive effect of inhibition control, cognitive flexibility, and perceived organizational support on teacher burnout can be explained by self-efficacy. Furthermore, the study variables collectively accounted for 63% of the variance in teacher burnout.
