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.

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.

Introduction: Emotion regulation problems can cause important disorders in children and adolescents. Since emotion dysregulation has major role in internalizing and externalizing problems of children and adolescents, adolescence is  an important opportunity for changes in emotional experiences, emotional regulation and also increasing mental disorders and generalized changes in social relationships. The aim of this research is to study the effectiveness of training emotion regulation skills in improvement of executive function and emotion regulation strategies of at risk adolescents. Method: The method of this research is experimental that we used pre- test and post -test with control group.24 teenage girls have been selected from hazardous areas of Tehran with accessible manner and randomly they have been appointed in experimental and control group.The members of experimental group got education program of emotion regulation skills in the base  of dialectical behavioral therapy that was derived from Linehan model  in 8 group sessions,while the control group don’t take any intervention.Results: Training emotion regulation skills increased the scores of adaptive strategies and decreased the scores of maladaptive strategies. Also there was an increase in total number correct of executive function variable and number of categories completed rather than control group.Conclusion: Training of emotion regulation skills can affect in modifying and moderating of emotional reactions in adolescents and also it can affects on involved cognitive processes.

This study examined the moderating effect of cultural and sex differences on the relationship between appraisal processes with academic stress among male and female Iranian and Swedish university students. On a sample consisting of 212 students [112 Iranian (male 32 and female 78) 100 Swedish (male 29 and female 71)] were administrated the primary and secondary appraisal processes and Academic Stress Questionnaire. The results of multiple regression model showed significant positive relationship between primary appraisal and academic stress among Iranian students and nonsignificant positive relationship between primary appraisal and academic stress among Swedish students. Results also indicated that there was a significant negative correlation between secondary appraisal and academic stress among Iranian and Swedish students. Results also showed that there was a nonsignificant positive relationship between primary appraisal and academic stress and a significant negative relationship between secondary appraisal and academic stress among both sexes. Therefore, the relationship between primary and secondary appraisals and academic stress by sex was not moderated. In sum, these findings emphasize that for the purpose of prediction of academic stress the functional properties of primary appraisal were dissimilar and the functional properties of secondary appraisal were similar in two cultural contexts and the functional properties primary and secondary appraisals were similar in tow sex groups.

Abstract:

There has been substantial interest in mindfulness as an approach to reduce cognitive vulnerability to stress and emotional distress in recent years, and mindfulness meditation practices have been incorporated into several interventions that are now widely available in medical and mental health settings. However, thus far mindfulness has not been defined operationally. Among the important questions that can be studied is whether mindfulness should be described as a multifaceted construct and, if so, how the facets should be defined. Several current descriptions of mindfulness suggest a multidimensional nature. The aim of the present study was to investigate the factor structure and psychometric properties of Five Facet Mindfulness Questionnaire (FFMQ) in Iran. 247 Iranian university student (188 women, 53 men and 6 undefined) filled following scales:  FFMQ (Baer, Smith, Hopkins, Krietemeyer, & Toney, 2006), Integrative Self-Knowledge (Ghorbani, Watson, & Hargis, 2008), BSCS(Tangney, Baumeister, & Boone, 2004) , Rumination Scale (Trapnell & Campbell, 1999), Penn State Worry Questionnaire (PSWQ; (Meyer, Miller, Metzger, & Borkovec, 1990), Vitality Scale (Ryan & Frederick, 1997), symptom checklist  (Bartone 1995), perceived stress(Cohen, Kamarack, & Mermelstein, 1983) & Anxiety and Depression Scale(Costello & Comrey, 1967).  The second order CFA showed that five-factor structure of FFMQ in first order and one-factor in second order did not fit the data well and EFA proved five-factor structure in first order and two-factor in second order of the scale that fit the data well. These results point toward conceptual distinction between facets of mindfulness. Mindfulness facets were shown to be differentially correlated in expected ways with several other constructs and to have convergent and divergent validity. Findings suggest that conceptualizing mindfulness as a multifaceted construct is helpful in understanding its components and its relationships with other variables, and suggested a need for reviewing the research and theory of mindfulness due to exposed facets.

The failures of memory function in post-traumatic stress disorder and its relationship with severity of symptoms need to take new approaches to improve the memory performance in patients. The aim of this study was to investigate the Effectiveness of emotional working memory Training on improvement memory in adolescents with Post- Traumatic Stress Disorder (PTSD). For this purpose, 4 adolescents (M: 2 F: 2) were selected available sampling by using 2 instruments (SCID-I) & (IES-R) The selected people– one by one were under emotional working memory training during 20 sessions. All people were assessed during three stages (pre-training, post- training and 2 month follow up) by children' Wechsler Digit Span Test (direct and reverse). Data were analyzed using the indices for trend changes, slope and the visual inspection of the charts; recovery percent index and effect size were used to determine the clinical significance. The results showed that emotional working memory training lead to increase in ability of participants in memory from pretest to follow up who suffering from Post- Traumatic Stress Disorders. Regarding the current study, it can be said that emotional working memory training is an appropriate choice for increase in memory in adolescents suffering from Post- Traumatic Stress Disorder

Abstract

the present study aimed to the comparison of the intolerance of uncertainty (IU) and short-term memory capacity in patients with obsessive-compulsive disorder and normal individuals. a total of 30 patients (16 female, 14 male) with obsessive-compulsive were selected using convenience sampling from the psychiatric clinics and centers of Tabriz were matched with 30 patients (16 females and 14 males) of normal individuals by demographic information, and all of them were assessed through Baher & Dougas’s intolerance of uncertainty scale and the Wechsler Digit span test subscales .Data were analyzed by multivariate analysis of variance (MANOVA) and as well as SPSS version 19. The results showed that there is a significant difference between the two groups in terms of IU (P<0/01) and the difference in patients with OCD is more than normal individuals. Also, there is a significant difference in terms of the short-term memory capacity (P<0/01) and the difference in normal individuals is more than patients with OCD . So it can be concluded that patients with OCD have less ability to tolerate uncertainty than normal people and short-term memory capacity in these patients is lower than normal people. Therefore, intolerance of uncertainty and low working memory capacity are two factors that may affect OCD symptoms and therefore exacerbate and perpetuate the disorder.

The aim of the present study was to investigate of the efficacy of bilateral repetitive transcranial magnetic stimulation on cognitive function in patients with bipolar depression.  In a single-blind experimental trial, 20 patients with bipolar depression who had been referred to Atieh clinical neuroscience center were selected randomly from April to September 2015. The patients received bilateral repetitive transcranial magnetic stimulation on left dorsolateral prefrontal cortex (10Hz) and right dorsolateral prefrontal (1Hz) during 10 sessions.  The subjects were evaluated through verbal fluency test, Rey Auditory-Verbal learning Test, Stroop Test, Wisconsin Card sorting Test, Beck depression inventory before and after the treatment. The data were analyzed by paired t test. Bilateral rTMS was caused to significant changes in executive function and verbal memory and depressive symptoms. No significant changes were observed in selective attention and verbal fluency (p>0/05). Bilateral repetitive transcranial magnetic stimulation is caused to significant improvement in cognitive symptoms and reduces the symptoms of depression in patients with bipolar depression.

Aim: The purpose of this study was to examine the effective of the Pennsylvania resilience program training on cognitive appraisal and achievement behaviors among university students.

Method: In this pretest-posttest nonequivalent-group design, 51 undergraduate students at Kharazmi University in experimental and control groups responded to the Cognitive appraisal scale (CAS, Lazarus, and Folkman, 1984) and the motivation strategies for learning questionnaire (MSLQ, Pintrich, Smith, Garcia, & McKeachie, 1991). The experimental group received 6 resilience training sessions (2 hours a session). Results: The results of multivariate covariance analysis indicated that the resilience program training was effective in increasing cognitive appraisal and achievement behaviors in short term. Conclusion: These findings suggest that resilience program training improve the achievement behaviors of university by letting them: 1) find their personal power (personal feeling, attitudes and beliefs), 2) find and make full use of their external resources (development of security and feeling of protection), 3) master their interpersonal skills and problem solving ability (such as persistence, humor and communication).

mind wandering is a pervasive and common phenomenon of human cognition that its role in performance of any field related to mind is undeniable. This study plans to investigate The causal relationship of mindfulness and mind wandering with mediating strategical engagement regulation, anxiety, depression and working memory. To this, 434 female students of Shahid Chamran University of Ahvaz were selected by multistage random sampling method and They got Mindful Attention Awareness Scale, Strategic Engagement Regulation Scale, Stress Anxiety Depression Scale, Stress Anxiety Depression Scale, The Working Memory Questionnaire and The Mind Wandering: Deliberate and Mind Wandering: Spontaneous Scale. Collected data were analyzed by SPSS and AMOS (version 21) and using structural equations modelling method. In order to earn the suitable model fitness indices, the item parceling method was used about mindfulness variable. Finally, on the base of values of some indices (for example, RMSEA = 0/06 and GFI = 0/98), model had a good fit. Also, all paths of the model except two paths: anxiety to working memory and anxiety to mind wandering were significant. In sum, this research results showed that mindfulness plays important role in mind wandering anticipation that transfers this effect through mechanisms as self-regulation, mood and working memory.

Abstract
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.

Abstract
The aim of this study was to investigate the role of working memory capacity and errorless and errorful practice on the learning the relative timing was a motor task. 50 Participants based on were selected aged 22±4 years as accessible samples randomly assigned to one of four groups (errorless low working memory capacity, errorful low working memory capacity, errorless high working memory, errorful high working memory capacity). This study was carried out in four phases. First phase (pre-test), subjects participated in 10 trials without knowledge of results (KR) on four-segment timing task. In the acquisition(ACQ) phase, a timing task with three different difficulty levels (simple, moderate, and difficult) was practiced in three sessions of 45 trials with feedback by experimental groups, except for control. In the 10-minute and 24 hour retention and 10- minute transfer tests, errorless group with low working memory capacity and errorful group with high working memory capacity had better performance than other groups. In the dual task tests (24-hour transfer) errorless group with low working memory capacity in the relative timing (intermediate times, RMSE) had better performance than other groups. These results indicate that the efficiency and efficacy of errorless and errorful practice interact with psychological indicators such as working memory capacity. These results suggest that implicit motor learning (errorless) may be beneficial for children with working memory capacity. Individual with high working memory capacity might benefit from learning explicitly (errorful). Results in dual task conditions support the implicit learning and reinvestment theories.

In this study we manipulate structure of combined practice (physical along with self-modeling of positive self-review) to examine its effects on motor memory reconsolidation process and motor transfer in children. 36 female students (9-12 years old) from Maktabi elementary school of Qom trained Dart throwing. Of the 15 trials (from 1.5, 2, and 2.5 meters in blocked order), Positive self-reviewing videos were provided in the pre-test. A week later, subjects practiced in 3 groups of combined constant, random and blocked practice. Paired samples T test of Means radial error between end of acquisition and tests showed significant improvement in all practice groups (P≤0.05) for 24 hour blocked retention test (after recall), significant improvement in only combined blocked practice group (P=0.016) for 24 hour constant retention test (after recall) and significant decrease in all practice groups for 24 hour transfer test (after recall). Therefore re-stabilizing motor memory during reconsolidation could occur in children and low variable (blocked) practice could lead to more improvements in reconsolidation process and transfer of motor memory in children.

In this research connectionist modeling of decision making has been presented. Important areas for decision making in the brain are thalamus, prefrontal cortex and Amygdala. Connectionist modeling with 3 parts representative for these 3 areas is made based the result of Iowa Gambling Task. In many researches Iowa Gambling Task is used to study emotional decision making. In these kind of decision making the role of Amygdala is so important and we expect that a model with two parts (thalamus and Amygdala) can have the best result in modeling participants decisions without considering any part for cortex process. For this purpose 56 participants composed of 20 men and 36 women wanted to do Iowa Gambling Task. Results show that the networks related to two parts model predict 62.57 Percent’s of participant’s decisions and the 3parts model has 68.46 Percent’s of that. In conclusion it can be said that three parts modeling has been more success than mathematical two parts model in predicting the performance of participants and the difference is significant. In other words cortex role in this kind of decision making is quite important.
