In pathology and treatment of learning disorders, special attention has been paid to executive functions. The aim of this study was to investigate the effect of computerized cognitive rehabilitation of working memory on improving the planning and organizing functions of children with special learning disorders of the reading type.

The statistical population included elementary students with special learning disorders of the reading type in Amol and Mahmoudabad in the academic year 1397-98 who were referred to learning disability centers. From this statistical population, 30 people were selected by available sampling method according to the inclusion criteria, and were randomly assigned to the experimental and control groups. The experimental group received 14 sessions of computerized working memory rehabilitation (Memory Gym software). For data collection, NAMA dyslexia tests, Raven IQ test and the Tower of London test was applied. Data were analyzed by multivariate analysis of covariance.

results showed that the computerized working memory rehabilitation group Showed significantly better performance in reaction time (p <0.01, F = 42), error response (p <0.01, F = 29.97) and test score (p <0.01, F / 91/36).

Working memory-based cognitive rehabilitation improves it by facilitating subprocesses related to the planning-organizing function.

The aim of the present investigation is to study the cognitive model of Rapee and Heimberg in explaining shyness. In the same vein, the mediating role of fear of negative evaluation and social-physique anxiety in the relationship between body image and Self-Focused Attention with shyness was investigated. Statistical population included all students studying at Mohaghegh Ardabili University in 2019-2020, among them, 222 people were selected using multi-stage cluster sampling. Data were collected using the Focus of attention questionnaire, Fear of Negative Evaluation Scale, Social physique anxiety scale, Cheeck-Briggs Shyness scale, and Body Image Rating Scale. Data were analyzed using structural equation modeling. The results revealed that that the variables of fear of negative evaluation and social-physique anxiety play a mediating role in the relationship between body image and focus of attention with shyness. In the face of social situations, a kind of mental representation of appearance is formed in the person that becomes the focus of attention, also attention is paid to the negative evaluation of others, and finally the anxiety caused by these two sources increases shyness, in other words, the cognitive processes of Rapee and Heimberg conceptual model of social anxiety also play a role in explaining shyness.

Social competence is considered as a fundamental dimension of human development, especially in adolescence. The goal of this research is investigating Psychometric properties of 6-item Perceived Social Competence Scale in high school students.
this study was a survey and standardization research. Population included all high school students of Mahmud-Abad city in spring of 1394 (2015), among them, 237 students were selected by cluster random sampling method. Questionnaires were used in this study was UCLA Loneliness Scale (UCLS-8), Prosocial Tendencies Measure (PTM), and Perceived Social Competence Scale (PSCS). In order to validating this scale, methods of Cronbach's alpha and test-retest reliability in 3 weeks were used for reliability and ostensible validity, concurrent convergent and divergent validity and finally confirmatory factor analysis were used by SPSS-21 and Amos-21.
Findings: internal consistency of items by Cronbach's alpha was 0.83, test-retest reliability was equal to 0.90. Convergent validity with prosocial behavior scale was 0.50 and divergent validity with loneliness scale was 0.42. Goodness of fit indicators of confirmatory factor analysis was desirable (X2= 22.63, df= 9, RMSEA= 0.07, GFI= 0.96).
with regard to findings of investigating the Psychometric properties of Perceived Social Competence Scale, as a valid and reliable scale for assessing social competence, can be used by experts of psychology and social sciences.
