The proposed link between brain laterality and individual differences in cognitive tasks provided the theoretical foundation for the present study. The main purpose of this study was to investigate this potential link, specifically between one aspect of brain function, namely hand dominance, and one type of cognitive task, namely the ability to perceive short intervals of time. The sample included 40 girls and 40 boys left hands and 40 girls and 40 boys right hands in school students fasa city  that were selected  with the help of the Edinburgh Handedness Inventory and also time Perception  measured  with  four methods of production, reproduction, verbal estimation and comparison by standard software .Regression analysis showed that age predicted negatively and significantly time perception to the measuring verbal estimation and production method. Handedness was positively and significantly predicted measuring verbal estimation method time perception. Logistic regression results also showed that Handedness predicted the time perception the measuring comparison method. In this study  , not showed significantly different between the sexes. Summarizes the results show that right-handed people than left-handers to perceive higher intervals of time but at the time discrepancies are close to each other have more wrong.

In regard to collecting data, method of the study was descriptive - instrument making one Item analysis, internal consistency cofferient and test-retest demonstrated that the items and factors were satisfactory. Confirmatory factor analysis, also, confirmed the model with five factors. Therefore CD had a proper validity and reliability to measure Cognitive Disability amony Iranian people. Thus, it can be employed as an instrument in related research and treatment.

Working memory is the comprehensive cognitive system that embedded attentional and memorial mechanisms and therefore can be used in systematic research of cognitive problems. Accordingly, the aim of this study was to investigate the developmental changes of working memory capacity, and its components, including phonological loop, visuospatial sketchpad, and central executive (inhibition and updating). A total of 356 children (8 and 12 years) recruited from primary school in Tehran were selected and tested. Digit Span, and the Kim Karad Visual Memory Test were used for measuring phonological loop and visuospatial sketchpad. Working memory capacity was measured by Backward Digit Span, and finally, the Stroop Task, and the Keep Track task measured central executive. Data analyzing showed as child growth, working memory and its components become more effective. More skills in arithmetic abilities, more flexibility in storage and processing, more experience in academic achievement and more use of metacognitive strategies can be possible reasons for the results of this study.

The purpose of this study was to investigate the mechanism of the effect of behavioral activation therapy (BA) through cognitive flexibility and emotional flexibility on the symptoms of women with major depressive disorder. This study was based on the single-subject design. The research sample consisted of five women with major depressive disorder (BDI-II), Beck Anxiety (BAI), Cognitive Flexibility (CFI) and Emotional Flexibility (EFI) at baseline and during the stage of depression. Treatment was evaluated. To analyze the data, trend, slope, and charts were used to determine the clinical significance of the percentage of recovery, percent reduction, effect size and Cohen index. The findings indicated that behavioral activation therapy significantly contributed to enhancing the cognitive flexibility and emotional flexibility of patients with major depressive disorder. In general, the results of the research indicated that the benefits of behavioral activation treatment as an effective intervention were used to increase the cognitive flexibility and emotional flexibility of women with major depressive disorder.

Creativity is recognized as a function or ability that emerges as genuine, valued and usefull. Each person's level of creativity can be measured by assessing their performance in the tests of creativity. One of the most commonly used tests of creativity is Remote Associates Task. The Remote Associates Task, developed by Mednick (1967), is recognized as a valid convergent thinking tool. The purpose of this study was to investigate the psychometric properties and the Farsi version of the Remote Associates Task. For this purpose, 482 students of Arak University were selected through cluster sampling method. Thus, at first 200 students were selected and answered the Remote Associates Task. After the initial refinement, some modifications were made to the initial version, and then 282 different subjects responded to the Remote Associates Task, insight problem solving, and Guilford's Alternate Uses test. Two classical approaches and item response theory were used to investigate the coefficient of difficulty of the items, construct validity, and reliability. Significant positive correlations of distance associations test with insight problem-solving test and lack of significant relationship with Guilford's Alternate Uses test indicate convergent and differential validity, respectively, and appropriate construct validity of the test. The results show the appropriate psychometric properties of the 30-item version of the Remote Associates Task presented in this study and it can be said that this test is effective and suitable for measuring convergent thinking in Persian.

Recent research has indicated the influence of bilingualism on many cognitive and emotional processes. The aim of the present study was to investigate the role of bilingualism in processing anger in Turkish-Persian bilinguals’ first (L1) and second (L2) language. To achieve this goal, 18 Turkish-Persian sequential bilingual students with an average age of 26 from different universities in Tehran were selected with targeted sampling to participate in this quasi-experimental research. Participants completed the language history questionnaire, the General Health questionnaire, and the Positive and Negative affect schedule questionnaire, in addition to a computerized task designed to induce anger and determine the meaningfulness of Turkish and Persian words and non-words. Repeated measures ANOVA revealed that the participants significantly spent more time on determining the meaningfulness of words when they were induced with anger in comparison to the normal condition. Moreover, they were significantly slower in selecting Turkish words compared to Persian ones. Regarding the comparison of the two languages in both conditions separately, paired comparison results demonstrated that participants’ reaction time to Turkish words in anger inducing conditions was significantly longer. Thus, it could be proposed that Turkish-Persian bilinguals are more involved in their first language in emotional states, specifically anger states, and the Turkish language has more and deeper emotional associations for them, hence their emotional involvement is stronger for their mother tongue than for their second language.
