Introduction: This research sets out to study executive functions in the schizophrenic patients with negative and positive symptoms and a healthy group on the Wisconsin Card Sorting Test (WCST), as an index of frontal lobe functions. Method: For this purpose, 32 healthy people and 32 schizophrenic patients was selected the Scale for Assessment of Negative Symptoms (SANS) and Scale for Assessment of Positive Symptoms (SAPS) were carried out on schizophrenic patients. Results of these scales indicated that 14 patients had negative and 18 patients had positive symptoms. WCST were administrated for the samples. Data were analyzed by MANOVA. Findings: results indicated that groups had significant differences in all five scales (Eta square=0/401, P=0/001, F (2, 61) =5/38). Groups in number of categories scale (P

Introduction: According to the studies, biological and endogenous factors can affect cognitive processes. The aim of the present research was to study the relationship between decision-making styles with the brain behavioral inhibition and activation systems and handedness. Method: The present study was descriptive correlational research with regression analysis. The participants included 269 university students selected from Bonab and Tabriz Payame Noor Universities via multistage random sampling. They completed the decision-making styles questionnaire of Scott and Bruce (1995), the brain behavioral inhibition and activation systems (BIS/BAS) questionnaire of Carver and White (1994), and Edinburgh’s handedness questionnaire. Data were analyzed by Pearson’s product-moment correlation, standard multiple regression analysis, and moderated regression analysis. Findings: The results indicated that there is a relationship between handedness with brain behavioral inhibition and activation systems, and avoidant decision-making style. There was a significant relationship between behavioral inhibition system with all types of decision-making styles, and between behavioral activation system with all three types of avoidant, rational, and intuitive decision-making style except dependent style; and both brain behavioral systems were able to predict the decision making styles. Besides, moderated regression analysis verified the moderating effect of handedness in mediating the relation between behavioral inhibition system (BIS) and avoidant decision-making style. Conclusion: Overall, the results of the study confirm that cognitive processes, like decision-making, are directly or indirectly influenced by endogenous and biological factors such as brain behavioral systems and hemisphere superiority.

Introduction: The purpose of this study was to assess the domains of cognitive abilities and affective styles of adjusting, concealing, and tolerating based on individual differences in morningness and eveningness personality tendencies. Method: For this purpose, initially 304 students of Urmia University were selected through multistage cluster sampling. Then morningness and eveningness types questionnaire was distributed among them to be answered. After analyzing the initial results, 60 participants were selected as individuals with morningness and eveningness and intermediate according to obtained scores in morningness and eveningness questionnaire. Finally, cognitive abilities and affective styles questionnaires were distributed individually among the participants in order to gather the data. The data were analyzed by using descriptive indicators, multivariate analysis of variance (MANOVA), one-way ANOVA and tukey post hoc test. Findings: Results indicated significant differences between dimensions of cognitive abilities based on tendencies of morningness and eveningness and intermediate and eveningness types in comparison with morning persons had higher abilities in some dimensions including inhibitory control, decision-making and attention.

Introduction: Given the protecting and aggravating role of cognitive emotion regulation strategies in Pathology, this study examined the mediating role of cognitive emotion regulation in the relationship between Brain-Behavioral Systems and impulsivity with craving in stimulant addiction. Method: In this study that was a descriptive and correlational design, 249 stimulants drug users who had been detoxified by purposeful sampling, and considering exclusion and inclusion criteria, were selected. Barratt Impulsiveness Scale, Behavioral Inhibition System (BIS) and Behavioral Activation System (BAS) Scales (Carver & White, 1994), short form of Persian version of cognitive emotion regulation questionnaire and desire for drug questionnaire were used to collect the data. Regression and path analysis were used to analyze the data. Findings: Sequential Regression analysis according to steps that had been suggested by Baron and Kenny (1986) reveald that maladaptive emotion regulation strategies can significantly have a mediating role between BAS and impulsivity with craving. Conclusion: Maladaptive emotion regulation strategies are one of the aggravating factors in craving related problems of stimulant drug users. This research suggests that intervention and relapse prevention programs must be designate considering the craving related emotion regulation strategies.

Introduction: The main objective of this study was to compare the speed of learning and information transfer in the brain hemispheres between female and male university students. Method: To do this, 60 students of psychology of Roodehen Islamic Azad University, including 30 males and 30 females, who had experimental psychology courses in the first semester of the academic year 1393-1394 were selected to make the sample of the study. To measure the performance of the hemispheres, the Mirror Drawing Device was used in order to see whether the transfer of effect took place. One-way variance (ANOVA) and SPSS16 program were applied to analyze the data. Findings: The results indicated that there was no significant difference between the genders regarding the information transfer between the hemispheres while gender had a significant effect on the speed of learning. Conclusion: The results revealed that the speed of learning in female subjects was higher than that in the male subjects.

Introduction: The main objective of this study was the assessment of neurofeedback and neuro-biofeedback training’s efficacy in decreasing Obsessive Compulsive Disorder’s symptoms. Method: This study was a quasi-experimental one with pre-test and post-test plan. The sample included 12 OCD patients who were randomly selected. The research instrument was Madzly Inventory. First the subjects had pre-test and then, they were randomly placed in three groups: Two experimental groups who had Neurofeedback or Neuro-biofeedback training, and one control group who only received medicine. The experimental groups had 30 treatment sessions for 10 weeks. In order to analyze the data, the covariance multivariate analysis was used. Findings: The results showed significant changes in symptoms’ reduction of OCD in neurofeedback training group in comparison to the control group (p

Introduction: Lateralization of the brain associated with cognitive functions. It is suggested that handedness is related to creative cognitive function as one of the lateralization results. This study aimed to compare the components of creativity among right-handed, left-handed and ambidexterity students. Methods: This study is an ex post facto research. The statistical population in this study consists of all high school students at Lamerd and Mohr cities in the second semester of the academic year 2013-14. To select target groups, two sampling methods were used. Group of 40 right handed students in the available method and ambidexterity and left-handed group are each separately 40 students in multi-stage random method, were selected. The subjects in this study responded to Edinburgh Questionnaire and the creativity test. Findings: The results of MANOVA analysis on average creativity scores and its components of students showed that the average of creativity and components of fluency and originality in right handed students are significantly lower than left-handed students, and the average of creativity and components of fluency, originality and flexibility in right-handed students are significantly lower than students who are ambidexterity. Conclusion: creativity and its components in ambidexterity and left-handed students are higher than those of right-handed students, it can be said that the right hemisphere stimulation and interaction in the two hemispheres may affect people's creativity.
