The present study investigated the relationships between perfectionism and feeling of fatigue and it’s dimensions. 400 undergraduate students of Tabriz university, were selected by the random multi-stage cluster sampling method. They filled the Fatingue Impact Scale and the Hill’s Perfectionism Inventory (PI). Analyzing data was performed via multiple regression analysis. Research findings revealed that perfectionism predicted cognitive, physical, social and total fatigue, significantly. It predicted 29%-39% of variance of fatigue dimensions and total fatigue. Based on the results of this study, one way propose that focusing on the role of perfectionism could be an important part of therapeutic interventions for the people with chronic fatigue syndrome.

The purpose of this study was to investigate the effect of load and capacity of working memory on cognitive control processes in the Stroop Task. 90 students of Payame Noor university of Tabas did working memory task and according to their results put into two groups. Each of these two groups performed the Stroop Task on two situations; In the first phase low load condition (present simple mathematical equations between successive attempts of the Stroop Task has been translated into Persian without the need to resolve them) and in the second situation high load (simple math equations presented in the Stroop Task and the need decisions regarding the accuracy of the answers given by pressing a button). Results of MANOVA on the reaction time to the congruent stimuli, reaction time to incongruent stimuli did not show any difference between two groups with high and low working memory capacity at the first situation. However, the difference between the number of correct and incorrect responses between the two groups using chi-square test was significant. In the second experimental situation, the group with high working memory capacity were clearly better. It was also revealed that increasing the working memory load in the group with low working memory capacity led to increases interference and reduces the number of correct responses.

The purpose of this research was to study of trend and content of the articles published in the Journal of Psychology, which as one of the first Iranian scientific journals in the field of psychology, has followed a general approach for publication of subjects. The research method using for this study was content analysis. For this purpose, all 60 issues of the journal were analyzed for determination of subject areas, research methods, the statistical methods used in the articles, the frequency distribution of citations to papers in Persian and English articles, and also the rate of article using in the new and old articles. The study population was all articles published in the Journal of Psychology from spring 1996 to winter 2012. which include 60 issues, and 352 articles. Content analysis check list was used as instrument in this study. The results showed that the most frequent subjects used were psychology of health, education and treatment effectiveness approaches, personality, learning and educational achievement and psychometrics. In terms of research method correlation methods, experimental, attitude survey, and retrospective studies respectively were the most using methods. In terms of statistical methods, correlation methods, analysis of variance, and t-tests had the highest frequency. Finally, analysing the references used in the journal showed that the rates of using foreign references were more than the Persian references. It was also found that single author articles gradually led in to collaborative articles.
