The aim of present study was to investigation the role of metacognitive beliefs and thought control strategies in test anxiety symptoms of students. In a frame of correlation design, using multi-stage cluster sampling among high school students of Estahban and Shiraz in the 93-94 academic year, 401 students (male and female) were selected and completed test anxiety inventory (TAI), metacognitive questionnaire (MCQ-30) and thought control questionnaire (TCQ). Data were analyzed using Pearson correlation coefficient and stepwise multiple regression analysis. Pearson correlation coefficient showed that the cognitive components of positive beliefs about worry, uncontrollability, danger and cognitive confidence had a positive relationship with test anxiety symptoms of students. Also, among thought control strategies, worry, social control and punishment had a positive relationship with test anxiety symptoms of student, but attention diversion had a negative relationship. The results of stepwise multiple regression analysis of variables combination showed that uncontrollability and danger, cognitive confidence, punishment and need to thoughts control predict test anxiety symptoms of students, respectively.  The results of this study suggests that one of important factors in incidence of test anxiety in students is metacognitive beliefs and copying strategies about them. Therefore, it is recommended that pay particular attention to metacognitive beliefs and copying strategies in the prevention programs or treatment of test anxiety.

This study aimed to determine the mediating role of self-regulation in the relationship between thinking styles and students’ test anxiety in Birjand University. The present study is a non-experimental one and of Structural Equations Modeling (SEM) type. The sample size consists of 300 students (150 males and 150 females) who were studying in Birjand University that were selected through multi-stage cluster random sampling method. They completed three questionnaires including Test Anxiety questionnaire developed by Abolqasemi et al. (1996), Self-regulation questionnaire by Pinterich and DeGrowth (1990) and Thinking Styles by Sternberg and Wagner (1992). Then, descriptive statistics such as mean and standard deviation and parameters of inferential statistics and path analysis were applied using AMOS software. The results showed that thinking styles explain 31% of the self-regulatory learning variance and thinking styles with mediation of self-regulatory learning explain 36% of the test anxiety variance. Thinking styles have an indirect relationship with test anxiety through self-regulation. Therefore, identifying different learning styles and skills through self-regulation of the amount of test anxiety they explained. And thus to reduce test anxiety set of programs. As a result, planners and therapists These findings suggest that self-regulation is necessary to reduce test anxiety, and also references to different learning styles as a key variable pay special attention

The aim of this study was to determine the effect of attention training on the reading performance of students with dyslexia .This was an experimental study with pre-test, post-test and control group. The samples were randomly selected and consisted of 30 female students with dyslexia that were 11-9 years old. They were randomly divided into experimental and control groups. The experimental Group received 20 sessions (Three times per week, each lasting 45 minutes) of verbal attention training program while the control group received only conventional education in school. Before and after the intervention, Assessment of Reading and Dyslexia (NAMA) were completed by the two groups. Before the intervention Toulouse-Pieron test screening for dyslexic students who had attention deficit was applied. The data were analyzed using analysis of covariance. The results showed that attention training program Increased the reading Performance of excremental group in comparison to control group (p <0/0005). Also the scores of experimental group were enhancing after the training. Attention training had a positive effect on reading performance of students with dyslexia and can be used to enhance students' reading performance. This method can be applied by psychologists, teachers and educators of special schools, parents and all those who are in communication with these children.

This study to do identifying processes and strategies of emotion regulation and designing developmental model based on self-regulation patterns. Thus, this study examined emotion regulation with a developmental perspective in children age 4 - 12 years In Tehran. To 108 children, scenarios including four emotions namely sadness, madness, worry and pain were read. After the stories were read to the subjects and duly understood by them, and once an emotional atmosphere was created, subjects had an emotion regulation interview (ERI) and observation. Findings show that emotion regulation developed from extra-organismic self-regulation (input and output) toward intra-organismic (central processing). This trajectory is situation, attention and perception change, responding and expression modulating and internal-cognitive regulation.

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

Low self-esteem is one of the key factors underlying psychopathology, such as test anxiety. It seems that the activation of positive self-representations in memory plays an important role in self-perception. The aim of this article was to determine the effect of strengthening memory representations on self-esteem in people with test anxiety. This study was based on a quasi-experimental design with pretest and post-test. According to retrieval competition approach, a training package was designed to promote self-esteem and after verifying its content validity by 5 expert psychologist, the intervention was administered in 10 sessions (a one-hour session per week). Participants were 10 high school students with test anxiety diagnosis which were selected by purposive and available sampling; and completed Spielberger Test Anxiety Inventory (TAI) and Rosenberg Self-Esteem Scale (RSES) before and after the intervention and also one month follow up. Data analysis was performed using one-way trend analysis (one-way ANOVA with repeated measures). The results indicated that this intervention could lead to improve self-esteem and decrease test anxiety in participants (p˂0.01) and this trend continued until one month follow-up. As a result, it seems that interventions on the factors underlying psychopathology, such as low self-esteem, can have beneficial as well as proactive effects in this area and We may be able to make changes in self-concept even with no deliberate challenge to the thoughts.

Multiple sclerosis (MS) is a demyelinating disease of the CNS that due to cognitive impairment, can reduce the quality of life in these patients. The aim of this study is to evaluate effect of computerized cognitive rehabilitation on prospective & working memory function in Multiple Sclerosis patients. 46 MS patients aged 20–40 who have the inclusion criteria, were randomly assigned to experimental and waiting-list control groups. Experimental group trained for 12 session with a Memory rehabilitation software and waiting-list control group did not receive any intervention and training of this group was postponed after conducting research. Daneman and Carpenter's capacity working memory and Retrospective-Prospective Memory Scale was applied at pretest, posttest, and follow-up. The results of repeated measures ANOVA showed a significant difference between the means of working memory in experimental and waiting-list control groups. Also, the results of the present study indicate that a significant difference between the means of prospective memory in experimental and waiting-list control groups. Moreover, the post-test and follow-up scores in the experimental group was not statistically different. So Computerized cognitive rehabilitation have significant effect on prospective and working memory performance in patients with Multiple sclerosis and it can be used as an effective and helpful method to improve memory performance of these patients.

working memory is the comprehensive cognitive system that embedded attentional and memorical mechanisms and therefore can be used in systematic research of cognitive problems. The aim of this study was to investigate the predictive role of working memory capacity and executive functions (shifting, inhibition and updating) for Obsessive Compulsive Disorder.  We selected 164 student   (90 male and 74 female)    from university of Tehran with random sampling method  and they completed Maudsley Obsessional – Compulsive Inventory (Hodgson & Rachman, 1977), the Digit Backward Span Task (workingmemory capacity), Forward Span task (Short Term Memory), Stroop (inhibition, Spreen & Strauss, 1998), Set- Switching Task (shifting, Rogers & Monsell, 1995) and Keep Track Task (updating, Martinez, et al., 2011). Data analyzing used regression showed working memory and executive function totally predict considerable amount (67 percent) of obsessive compulsive predisposition. Therefore it can be concluding, obsessive people have crucial weakness in storage, monitoring and executive cognitive function (in general attention control) and we can use training in these functions as treatment strategies.

Abstract

Background & Aims: The aim of this study is to investigate the effect of strop on the psychological refractory period.

 Materials & Methods: The present study is of semi-experimental. 20 students of Chamran University of Ahwaz, chosen in reach; participated in the study with average age of 23/45±1/45. Each of the participants did a test of strop effect dual task within four intervals of 50, 100, 300, 900 ms between asynchronous onset of the tasks in both congruent and incongruent conditions.

Results: The results of repeated measurement test with (p>0/05) significant indicate that response time of the congruent stimulant is quicker compared with the incongruent one. In short intervals, the automatic process of reading the word had no overlap with the process of naming the word.

Conclusion: Therefore, strop effect in short intervals was not effective and the incongruent condition of strop effect makes the analysis of stimulant complex during the phase of choosing the response. Intra-group difference and internal inconsistency of two stimulants within the sequence of congruent and incongruent dual task increased the response time of the second stimulant. So, increase in the complexity of the first stimulant causes the longest delay of the second one.

The crucial difference between people with OCD and non-clinical individuals would be the presence of OCD-related dysfunctional beliefs. compulsions are aimed at undoing the intrusive thoughts.  With respect of core symptoms of Obsessive Compulsive Disorder(OCD) deficit in cognitive inhibition is probable. But results are inconsistent in this field. Here researchers are aimed to study the probable IOR deficit in clinical sample of compulsive washing . this study is a causal- comparative research.  Beck Depression Inventory - version II (BDI-II), Obsessional Beliefs Questionnaire- 44 (OBQ-44) and emotional Inhibition of Return test were administered of  47 clinical samples of compulsive washing. The results of MANOVA analysis showed that there is no differences between two groups in IOR (F_(4,42)=-0.578, P=0.735; Wilk’s Lambda= 0.955; Partial η²= 0.045). Moreover there is a significant deference between reaction times in valid and invalid trails  (t= 4.209; P≤0.01) that shows the general IOR phenomena in participants. This research failed to show  cognitive inhibition deficit  in clinical samples of compulsive washing according to their dysfunctional beliefs.IT seems that IOR deficient is not detectable in OCD patients according to exogenous attention. Other theoretical and experimental implications are discussed.

The project aimed to assess of biofeedback’s effect on anxiety and waiting anxiety symptoms using researcher-built instrument. The research design for this study was “Pretest- Posttest with Control Group Design”. The statistical population consisted of people with generalized anxiety disorder (GAD) in the 19-45 age range. This survey was based on a sample of 19 patients with GAD who were systematically drawn from 70 students with the high level of anxiety and then randomly assigned into experimental (n=10) and control (n=9) groups. At the percolation step, Anxiety disorder interview schedule for DSM-IV, Beck anxiety inventory and Waiting anxiety employed for the evaluation of the research variables. Biofeedback’s treatment using researcher-built instrument was performed on testable samples of the experimental groups. The data were analyzed using univariate analysis of covariance (ANCOVA). The covariance analysis revealed that biofeedback’s researcher-built instrument could help reduce anxiety (P<0.01) nevertheless no significant difference between experimental and control groups was observed in regards to waiting anxiety. The report suggested, easy availability of home version of biofeedback in large-scale in ensuring optimal level of its ability which can be subsequently employed on a broad spectrum of disorders.

Obesity is one of the most important problems which threatens the global health. Healthcare organizations spend a
large amount of money to predict and treat obesity every year. The most common treatment for obesity is
concentrated on shaping a new lifestyle with more exercise and healthy diet. But a multitude of dieters fail. In this study, the role of cognitive processing in dieters` success or fail was investigated. Participants were
successful (N= 42) and unsuccessful (N= 45) dieters between 18 and 40 years old. Attentional bias, positive
implicit association, and working memory capacity were measured by dot-probe task, a modified
version of implicit association test (IAT), and N-Back task. Results indicated that unsuccessful dieters showed
greater attentional bias to (d= 0.69) and more food preferences for (d= 1.06) high-calorie food pictures.
Nevertheless, there was no significant difference in implicit associations for high calorie food and in working memory capacity between the groups. These results were congruent with some previous studies and they were discussed based on dual-processing model.

The present research aims to examine the effect of teaching studying methods of reading and comprehension, note-taking and writing, and exam techniques and stress management with emphasis on cognitive and meta-cognitive strategies on academic achievement and motivation achievement among Iranian students with residency in Tajikistan. For this purpose, using empirical method and multi-group pre-test and post-test design, 80 students were considered in four groups(3 experimental groups and 1 control group). Response was given to Hermans achievement motivation questionnaire by the students at four groups and their Grade Point Average for previous year was registered, and the individuals in the experimental groups were trained during 10 sessions. After intervention, Hermans achievement motivation questionnaire was refilled by the students and their new Grade Point Average was registered. Ultimately, the research data were analyzed via Multivariate analysis of covariance (MANCOVA). Results of statistical analyses indicated that training studying techniques of reading and comprehension, note-taking and writing, and exam techniques and stress management affect achievement motivation and academic achievement.

The present study attemps to investigate overgeneral autobiographical memory and relationship with problem- solving deficits in depressive and anxious individuals. For this reason, 15 depressive, 15 anxious and 15 normal individuals were chosen from the students of estahban  payam noor university, that were the clients of the counceling clinic. In this study, after completing the Beck Anxiety Inventory(BAI) and Beck Depression Inventory(BDI), Autobiographical Memory Test And Means- ends Problem- solving task was used. To compare the overgeneral and problem- solving in 3 group of depressive, anxious and normal individual, data were analyzed with Analysis of Varience(ANOVA) And the Tukeys test was used to compare the pair groups. The results revealed that overgeneral in autobiographical memory depressive individuals is more than anxious and normal ones. Depressive individual are more inefficient problem solving solution to distressed and healthy people.So, according to Williams models depressed people because negative mood and bias in processing information not only in retrieving autobiographical memories are exclusively trouble but this was a problem retrieving, problem solving and also affect their problems and makes solutions less effective to produse.

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.
