Abstract
| Time perception is one of the important cognitive functions of the brain, and it refers to the mental sense of time by a person. This ability not only affects all human activities but also affects our mood and emotions. The present study was applied in a semi-experimental design with pre-test and post-test for two experimental and control groups. Subjects were 40 men and women (20 males and 20 females), which were selected by available sampling from bachelor's and master's degrees and divided into two peer control and experimental groups based on gender and education. All subjects were tested by production time task of 30 and 60 seconds by chronometer before and after the intervention. The experimental group was exposed to induction of three stages of negative, positive mood, and anxiety state, and the control group were tested by the same method in neutral state. The results of variance analysis with repeated measures in the production time task showed, individuals in positive mood and anxiety estimates time faster than neutral state, and also time perceived faster in positive mood in compare to anxiety state. Furthermore, individuals in the Negative mood perceived time slower than neutral state. Based on the result of this study, it can conclude that people experience time faster in positive mood and anxiety state, while in negative mood, people experience time slower. |

Abstract
The aim of this study was to evaluate the effectiveness of cognitive rehabilitation on improving working memory of adolescents with traumatic brain injury. The method of this research was quasi-experimental pre-test-post-test with control and follow-up groups. To conduct this study, 20 adolescents aged 9-18 years with traumatic brain injury referred to medical centers in Sadaf Shahriar (Parandmehr Clinic) were selected by convenience sampling and randomly assigned to two groups of 10 experimental and control. To measure the dependent variable of working memory, Wechsler scale 4 subtests (auditory measurement of working memory) and Benton test (visual-spatial measurement of working memory) were used. The experimental group underwent cognitive rehabilitation intervention (12 sessions of 45 minutes). Analysis of variance with repeated measures was used to analyze the data. The results showed that there was a significant difference between the experimental and control groups in pre-test, post-test and follow-up of working memory performance. The results showed a significant difference between the mean scores of working memory (auditory and visual-spatial measurements) of the experimental group and the control group in the post-test. In addition, there was no significant difference between post-test scores and follow-up in the experimental group, which showed the effect of cognitive rehabilitative perstability on working memory performance in adolescents with brain injury. Therefore, cognitive rehabilitation has a significant effect on improving working memory performance in patients with brain injury and can be used as an effective and useful method to improve working memory performance in adolescents with brain damage.

Abstract
| People with borderline personality disorder experience problems in a variety of cognitive areas, including information processing, decision making, planning, memory, and problem solving. The aim of the study was to modeling the intermediate role of metacognitive awareness on the relationship between overgeneral autobiographical memory and problem solving. The research was fundamental and in terms of implementation method was correlational. The statistical population included all individuals with borderline personality disorder who referred to psychological and psychiatric clinics in Kurdistan province in 1397-98. 300 patients with diagnosis of borderline personality disorder based on clinical interview and willing to participate in the study were selected. They answered the Autobiographical memory test, metacognition awareness questionnaire and social problem solving inventory. Data were analyzed using Amos software. Findings showed that overgeneral autobiographical memory has a direct effect on problem solving skills and metacognitive awareness with coefficients of 0.17 and 0.20, respectively. Also, the direct effect of metacognitive awareness on problem solving was 0.35. Overgeneral Autobiographical memory predicted 4% of the variance of metacognitive awareness, and Overgeneral autobiographical memory with metacognitive awareness predicted 17% of problem-solving changes. On the other hand, the indirect effect of Overgeneral autobiographical memory on problem-solving skills was 0.07, which shows that the indirect effect of Overgeneral autobiographical memory on problem-solving skills is significant. Therefore, it can be concluded that metacognitive awareness acts as a mediator as an observer, which increases the scores of problem-solving skills. |

Abstract
Executive dysfunction is a hallmark of traumatic brain injury (TBI) and is associated with significant complications. Deficiency in problem-solving, emotion regulation, and attention is one of the most common phenomena after brain injury. This study aimed to evaluate the effectiveness of short-term intervention of dual executive function on problem-solving, emotion regulation, and selective attention in patients with traumatic brain injury. This quasi-experimental design used pre-test and post-test with a control group. Twenty subjects with brain injury were selected with the Purposive sampling method. They were randomly entered into two experimental and control groups (10 in the experimental group and 10 in the control group). After performing the pre-test, the experimental group received the short-term intervention and double executive function in 8 sessions of 90 minutes, while the control group did not receive any intervention. The assessment was performed in two stages of pre-test-post-test using a set of software tests of the Tower of London, Stroop and John and Gross (2003) Emotion Regulation Questionnaire. Analysis of covariance was used to analyze the data. The results showed a significant difference in the mean scores between the experimental group and the control group in all variables after the test. Therefore, it can be concluded that short-term intervention of dual executive function has a significant effect on improving attention, emotion regulation, and problem-solving in people with traumatic brain injury.

Abstract
| Due to the importance of rehabilitation among children with special learning disabilities, the aim of this study was to evaluate the effect of brain Gym on suppression of theta/alpha ratio and working memory of students aged 8 to 12 years with dyslexia or dysgraphia. This research was a quasi-experimental study with a pre-test and post-test design with a control group. The population of this study included all girls and boys with reading or writing disorders referring to special centers for learning disabilities in Kermanshah. The convenience sampling methods were used. For this purpose, according to the inclusion and exclusion criteria, 20 students aged 8 to 12 years were selected and randomly allocated into two groups of 10 people. The experimental group were received brain Gym intervention for 20 sessions of 20 minutes over 10 weeks. In order to record the brain waves of the participants, a dual-channel neurofeedback device was used. Moreover, the Wechsler memory software was used to measure their active memory. To analyze the data, univariate one-way covariance analysis and multivariate one-way covariance analysis were used using SPSS software version 26. The results showed that the ratio of theta waves to alpha in the experimental group was significantly reduced and active memory span in the experimental group was significantly increased compared to the control group (P < .05). The findings of this study indicated that brain exercise can significantly suppress the ratio of theta waves to alpha and also improve working memory among children with special learning disabilities. The findings confirm the neurological evidence for the positive effect of the brain Gym intervention on the modulation of brain waves and working memory in children with dyslexia or dysgraphia. |

Abstract
Risk preference, the degree of tendency to take risk, has a fundamental role at individual and social health and is divided to risk seeker and risk averse. Therefore, the study of neural corelates of risk preferences is essential at the field of psychology and psychiatry. The current study aimed to examine and compare an ERP component named P300 between subjects with different risk preferences.
Method: 28 people placed in two groups of risk seeker and risk averse (14 each group). Subjects performed simple gambling task. ERP data were processed by MATLAB software and ERPlab. Repeated measurement ANOVA was used to analyze data.
Results: analysis of behavioral data presented that risk seekers selected low risk option more than high risk, but there was no significant difference of reaction time between groups. ERP analysis showed a significant decrease of P300 amplitude in risk seekers compared to risk averse when selecting high risk option. This result shows the importance of the differences in dopaminergic and motivational pathways of risk seekers during reward processing compared to healthy and risk-averse groups. Based on this result, it may be possible to consider the P300 component as a suitable indicator in clinical evaluations.

Abstract
In spite of increasing importance of attentional control in conceptualization of psychopathology, there are a few scales to measure it. It is necessary to use valid and reliable scale to study this construct in Iranian studies.This study aimed to provide and investigate psychometric characteristics of Persian version of the attentional style questionnaire.The sample of 426 students were selected by available sampling and completed persian version of the attentional style questionnaire, attentional control (Derryberry &Reed, 2002) and repetitive thinking (Ehring et al, 2011) scales. Construct validity were evaluated through confirmatory factor analysis. Convergent and divergent validity were assessed by pearson correlation. Reliability was calculated using Cronbach s alpha method, test-retest and Composite reliability.factor analysis indicated that two-factor model (congnitive avoidance/distractibility and focusing) provided good model fit. Significant correlations between these factors and attentional control, and repetitive thinking scales confirmed convergent and divergent validity. Cronbach s alfa for both factors were 0/75 and test-retest coefficient for cognitive avoidance/distractibility and focusing were 0/88 and 0/73 respectively also composite reliability were 0/81 and 0/84 respectively. According to the results, Persian version of attentional style questionnaire characterized two factors and has been demonstrated to have acceptable validity and reliability to use in psychological researches in Iranian population.

Abstract
| Making risky decisions in adolescents has become a major public health concern and understanding the correlations affecting this process makes it possible to implement prevention plans. Therefore, the present study was conducted to investigate the effect of positive and negative mood induction on risky decision-making by moderating high behavioral brain systems. In order to meet this aim, 327 adolescents aged 18-13 years in Isfahan were randomly selected and screened through the Behavioral Brain Systems Questionnaire (BAS / BIS). Based on the standard score, two groups of 24 participants including high BAS and BIS were selected. The members of each group were randomly divided into two equal subgroups, we induced positive mood in the first subgroup and negative mood in the second subgroup using Pieces of emotional movies. Participants completed the Balloon Risk Test (BART) and the Positive and Negative Emotion Scale (PANAS) before and after mood induction. Results of data analysis by univariate factor covariance analysis showed that there is a significant difference between inducing positive and negative mood on risky decision making (p≤ 0/05) and positive mood leads to increased risky decisions, The findings also showed that behavioral brain systems as biological personality traits significantly moderate the effect of mood induction on risky decision making (p≤ 0/05). This means that adolescents with a high behavioral activation system have more hyperactivity when faced with positive moods and they are more at risk than people with behavioral inhibition systems while adolescents with behavioral inhibition systems, on the other hand, are more sensitive to negative moods and signs of punishment and they are more cautious. |

Abstract
Significant psychological changes in extremely cold regions are considered as natural human reactions. Antarctica has very cold conditions and is considered a natural laboratory for many studies in various fields. Survival, in this harsh environment, is unmanageable without human preconditions; Antarctica with a focus on resilience and psychological adjustment, an opportunity for the individual to approach the study of psychological adjustment, examining the impact of weather conditions, limitations, isolation and lack of daylight, etc. on mood changes, stress and dynamism. is showing. In this article, the psychological changes of six researchers, who are twenty-three days of scientific travel in the cold region in the south of the region, are conceptualized with a systematic concept. In terms of methodology, thematic analysis and collected categories, interviews, observations and documentary analyzes have been used. Researchers' experiences were analyzed in the field and the emerging factors were categorized as attitudes, strategies and. These three factors were divided into thirty-six positive and negative factors at the individual and group levels. Theoretically, positive and negative factors are supported by force field theory, which contribute to the very cold region through conceptualization. Positive attitudes based on the data collected in this exploration include: self-awareness, self-direction, self-control, self-efficacy, self-confidence, self-motivation and self-optimism. On the other hand, negative attitudes are self-awareness, lack of self-direction, conflict with self, inefficiency, self-doubt, self-destruction, self-contradiction and pessimism. There are positive and negative strategies for strategies such as attitude at the individual and team level. In a person, positive strategies include: positive self-talk, positive thinking, meditation, muscle relaxation, spiritual recitation, self-control, and negative strategies include negative self-talk, negative, confusion, justification, religious belief, and loss of self-control. . On the other hand, different strategies with teammates in the direction of positive expressions such as humor, team coordination, control control, team performance, control of negative effects, accessibility and in part including nagging, disagreement, deviation from self-success and immoral reaction. Is. Peacefully, positive and negative factors, such as attitudes, strategies, and positive and negative effects on the environment, in fact, and the conflict of all the factors that lead to specific action in the face of various difficult situations.

Abstract
Socio-emotional development is one of the fundamental bases of individual and social health. The present study aims to investigate the developmental trajectory of socio-emotional tendencies (SET) and its components in preschoolers. Our sample was 447 healthy Iranian preschoolers (girl=47.4%) aged 48-78 month-old (mean=66.57, SD=6.79). they were from Tehran, Bandar Abbas, Mashhad, Zarand, and Tabriz as the representative provinces of the Iranian population, based on the geographical distribution and socioeconomic status. We used the Persian version of the Kindergarten Inventory of Social-Emotional Tendencies (KIST) which consists of six components. It included hyperactivity-maladaptive behavior, social skills, communication skills, daily living skills, eating behavior, and separation anxiety symptoms.
We used Kruskal-Wallis test to investigate the developmental trajectory of SET. Results showed that there were significant changes in daily living skills and separation anxiety symptoms during 6-month periods, meanwhile there were no significant changes in the other four components and SET in total. Then, the Games-Howell post-hoc test was performed to follow up the observed differences among age categories. Results of the present study showed that SET doesn’t change significantly in early childhood. It propose that the critical period of the socio-emotional ability development occurs sooner or later

Abstract
Mental representations are to be considered as the most advanced aspects of human cognition and in addition to their own physical representations, representations of social cognition of others can also affect the mental experience of each person's ownership of their body. Accordingly, the present research as a quasi-experimental study based on repeated measures, was conducted in order to investigate the effect of social cognitive representation on the mental property of the body. The population of the study consisted of all Students of Payame Noor University of Tehran from which 61 females and 47 males were selected by convenience sampling. The research instruments included Cohen and Botvinick's (1998) Rubber Hand Illusion Test, and Longo, et al.'s (2008) Rubber Hand Ownership Experience Mental Report Questionnaire. Induction of representations of social cognition was based on the three-dimensional mental model of social cognition by Tamir and Thornton (2020). The collected data were analyzed by repeated measures analysis of variance using SPSS-22 software. According to the findings, the error score of the rubber hand was higher than the rubber hand with the color close to the body and green, which was defined in terms of the factors of the levels of the three-dimensional model of social cognition at the extreme level, and lower than the blue rubber hand, which was at extremely low levels of the mental three-dimensional model. The results indicated that in social relations, the identification of individuals with those who have gained a higher social status in mental evaluations can be more than those who have gained a lower social status in mental representations.
