Abstract
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.

Abstract
The current research was conducted by the aim of studying the moderator role of age, Intelligence, and gender in relation to the Executive functions and reading function of elementary students.The sample included 250 students (124 boys and 126 girls) in elementary level that were selected by Multi-stage cluster sampling method among students of Karaj. Different functions were measured as these: Reading through reading test of Karami-noori and Moradi, intelligence by Raven's Progressive Matrices, working memory by Memory span test, attention by Continuous Performance Test, and planning and inhibition by Behavior Rating Inventory of Executive Functions (brief). Statistical methods of Pearson correlation and regression analysis were used.The correlation results showed that there is a positive and significant relation between executive functions (working memory, inhibition, subjective planning, and attention) and reading. Regression analysis result showed that intelligence and gender have not a moderator role in the relation of executive functions and reading. But, age had a moderator role in the relation of executive functions and reading. The results of this research was consistent with Miyake's theory that believes executive functions are separate but related to each other, and individual differences of the students in these functions should be considered, because they affect their school performance.

Abstract
In different parts of the world, people speak different languages to each other. Some parts of the world are more linguistically rich and more than one language is spoken in those regions. The aim of this study was to evaluate and evaluate the executive functions of the brain including cognitive flexibility, selective attention and response inhibition in monolingual and bilingual male and female students of Bu Ali Sina University of Hamadan. This research has been done by descriptive and causal-comparative method using complex Stroop computer test. The statistical population selected for this study were bilingual and monolingual students of Bu Ali Sina University. The test was performed on 214 male and female students. Data obtained from 165 students were analyzed by independent t-test and one-way analysis of variance. The obtained results showed that there is a significant difference between gender and executive functions studied in this study. But there was no significant difference between bilingual and monolingual individuals with these functions. In this study, we concluded that gender affects the executive functions of the brain, but bilingualism and monolingualism do not affect the executive functions of the brain.

Abstract
The present study aimed to investigate the accuracy, bias, and severity of gender-related facial emotion recognition among normal adolescent girls. The research design was analytical cross-sectional study. The statistical population of the present study was adolescent girls from the high schools of Lahijan city in the academic year 1402-1403, and the sample size was 243 people who were selected from public school students using the available sampling method and based on the inclusion and exclusion criteria. The research tool was the emotion recognition/perception test designed using the NimStim Set of Facial Expressions (2009). The data were analyzed using the student's t-test, Pearson's chi-square, and chi-square goodness of fit tests. The results showed that adolescent girls had greater accuracy in recognizing women's facial emotions and showed more errors when recognizing men's emotions. In addition, happiness and disgust were recognized more accurately (with less errors) in men, same as sadness, fear, and anger in women. Adolescent girls also showed bias when recognizing facial emotions in men and women. This bias was associated with a greater selection of disgust in men's faces and a more selection of surprise and fear in women's faces. Finally, adolescent girls perceived facial emotions in women more intensely than in men. In addition, adolescent girls perceived happiness, sadness, and disgust in men more intensely, and fear and anger in women more intensely. Therefore, the gender of the emotion expressers affects the perception and recognition of facial emotions in adolescent girls.
