Visual-spatial component of working memory and short-term memory in students with learning disorders and comparison with normal students

Sara Agha babaei

The aim of this research was to investigate visual-spatial component of working memory and short-term memory in students with learning disorders and comparison with normal students.
30 3rd grade elementary students with learning disorders and 10 3rd grade elementary normal students were selected through multistage random cluster sampling. The instruments were Scale for Identifying Students with Spelling Learning Disability, Keymath Test, Reading Level Diagnostic Test, Wechsler Intelligence Scale for Children (WISC), Clinical Interview and Corsi Blocks Task for assessing visual-spatial component of working memory and short-term memory. Data were analyzed by ANOVA. The results showed that there is a significant difference between students with reading, mathematics and spelling learning disorders and normal students in visual-spatial component of working memory and short-term memory. Students with mathematics disorder had lower performance in these components. Students with learning disorders particularlymathematics disorder had deficits in visual-spatial component of working memory and short-term memory. This problem should be assessed in order to plan appropriate interventions.

Comparative study of working memory performance, behavioral activation system (BAS) and behavioral inhibition (BIS) based on the dimensions of stress in adolescents

Sohrab Amiri

The aim of the present study was to investigate the amount of performance in working memory, and also comparing the dimensions of behavioral activation system (BAS) and behavioral inhibition system (BIS) in different levels of stress. For this purpose, first, 560 persons of high school adolescent students (including boys and girls) of Hamadan's schools were selected through a multistage cluster sampling. After the initial data analysis, 87 of them, based on final score distribution (Z Standard) were chosen. Finally, in order to test the hypothesis of this study, participants were have studied to measure working memory and behavioral inhibition and behavioral activation systems. The collected data were analyzed using a Multivariate analysis of variance, ANOVA and post hoc tests. Results showed that there is no significant interaction between gender and stress variables considering the working memory and behavioral inhibition and activation system. On the other hand, results showed that high stress levels can lead to a decline in working memory function and participants with high levels of stress were also at higher level in terms of activity of behavioral activation system (BAS) and behavioral inhibition system (BIS).

The role of metacognitive knowledge in the relationship between class management and second language achievement.

Mohammad Naghi Farahani

The relationship between class management with learning achievement had been attended by different researchers, but the psychological mediators can added the best obvious of this relationship. In the present research, the role of metacognitive knowledge and class management of teachers in predicting of English achievement have been conducted. 221 English teacher-student completed 3 sub-scales of class management (abdollahi, et.al., 2014) and metacognitive believes (vels et.al.,2004). English grade point average of three classes of teachers has been the criterion of English achievement of their students. The results of stepwisel regression analysis showed the class management variables enter in the equation in the first steps. 52 percent of variance of English achievement predicts by 3 component of class management. In the last stage 1 percent of variance of English achievement added to the total of variance. This results show that although the most important of English achievement can predict by class management variables, but the metacognition believes of teachers can increase this prediction.

Impact of working memory capacity on temporal processing in preschool children

Sara Jafarpoor

Since working memory capacity (WMC) predicts individual differences in the wide range of abilities, this experiment tested the effect of WMC on time perception in preschool children.
At first, 108 children’s working memory capacity were measured by CANTAB tests and then 21 children with high working memory capacity and 20 children with low working memory capacity were assigned. Then, both groups performed two reproduction tasks they instructed to reproduce 700 and 3000 millisecond intervals in mono task, and to reproduce 3000 ms with a performing concurrent non-temporal task as a dual task. Data analyzed by mixed design ANOVA and post hoc tests. Results showed that in mono task, accuracy of high WMC was better than the low WMC group. In dual task, although there was no significant difference in the accuracy of reproduction task, children with high WMC had better performance in non-temporal task. Furthermore, children with low WMC were more variable performance than high WMC in all intervals.

Cognitive bias in emotional information processing in anxiety, depression and normal people

Mansur Beyrami

This study aim to compare the cognitively biased information processing in anxiety, depression and was normal people. The study was causal-comparative study of 50 subjects anxious subjects, 50 subjects with depression and 50 normal subjects were formed by students of Tabriz University of Medical Sciences were selected using data Bvdnd.grdavry anxiety scales and Beck Depression scale psychological symptoms and clinical interviews, tests, and test complete root words were a reminder properties and data were analyzed using multivariate analysis of variance. The results showed that explicit and implicit memory between the three groups, anxious, depressed and normal in terms of positive, negative, and there was a significant threat, while threatening words of anxious, depressed subjects with negative words and positive words of ordinary scores were higher. But there was no significant difference in terms of neutrality between the three groups. It can be concluded that information processing in explicit and implicit memory bias creates and causes the information to be more consistent with the mood.

The effect of different recall distance‌s on explicit motor memory consolidation

Parvaneh Shamsipoor

The purpose of this study was to examine the effect of different recall distance s on explicit motor memory consolidation. Thirty Six students were randomly divided into three groups with distance of immediate, 6, and 24 hours in recall test. This research consisted of two phases of acquisition and recall. In acquisition period, all groups practiced the task for 15 blocks of 80 trials (five epochs of 400 trails). Then in recall phase, all experimental groups were practiced five blocks of 80 trials (one epoch of 400 trails). Also, all groups practiced the alternating serial reaction time task in each epoch. Data were analyzed with using the ANOVA repeated measure. Results showed that in acquisition phase the group main effect and interaction effect between group and epoch were not significant. But epoch main effect was significant and practice lead to inducing sequence reaction time in third epoch related to other epochs. In recall phase, the epoch main effect and interactive effect between group and epoch were significant, but group main effect was not significant. Results in Duncan Post Hoc showed that only group with 24h off line periods, in recall test, had the better performance than acquisition phase. Practice in group with 24h offline lead to decrease the reaction time than other group .Our Results indicated that 24h offline period for recall test is better time for optimal performance.
