Emotionand cognitionconstructs constitute twobasic dimensions ofhuman psychologicalstructureandtheexplanation of performanceis onlypossibledue to theinteractionof thesetwo dimensions.The aimofthis study wasto investigate student’s information processingspeed based ontrait/stateanxiety.From large population ofNajaf Abadcityhighschoolstudentsaccording to inclusion criteria and extreme scores of distribution of Spielberger Trait and State AnxietyScale (EPQ-R)fourgroups(highstatanxiety, lowstatanxiety, hightraitanxiety&lowtraitanxiety N=15) wereselected and assessed by Speed-of-processing tests (Zahlen-Verbindungs-TestOswald & Roth, 1978) and Sitzwohl’s Coding Test (KDT)(1995). Theresultsofmultivariate analysis of varianceand Bonferenipost hoctestsshowed thatthere aresignificant differences between fourgroups in speed-of-processing andcoding .Theresults alsoshowed thatspeed-of-processinginstudents with low trait and low state anxietyis faster thanstudentswithhightrait and high stateanxiety. Based on the findingsof this studycan be said thatanxiety plays an important role incognitive functionsandinformationprocessing speedofandhigh anxiety(trait /state) causes interferenceininformation processingspeed, and ultimately cognitive functions.

Abstract
The present research aims to compare the cognitive performance of the adolescents suffering from MDD and PTSD in the working memory and information processing. the selected sample in this casual-comparative study included 15 MDD patients, 15 youth PTSD subjects and 15 normal subjects who were matched by age, IQ, sex as well as social and economic status variables. The tool package employed in this investigation comprised child depression inventory (CDI), State-Trait Anxiety Inventory, Impact of Event Scale (IES-R), Wechsler’s Memory and Intelligence Test, and The Information Processing Index Test. Findings were analyzed using the ANOVA, MANOVA analysis statistical method.as indicated by our result, in the verbal memory there is a significant difference between groups of depression and PTSD and between depressed and normal subjects. in the reverse spatial working memory there are significant differences between normal and PTSD. in the visual memory and information processing, the significant difference is between normal and both PTSD and depressed.The findings of this study confirm the disorders of working memory and speed of information processing in adolescents with depression and post-traumatic stress disorder.

Abstract:
The present study was conducted with the aim of evaluating the effectiveness of the educational package of basic psychological processes on improving the processing speed and mathematical progress of elementary school students with learning disabilities in mathematics. The research method was quasi-experimental with a pre-test-post-test design with a control group. The statistical population of this research included all female students with second grade math disorder who have referred to Tolu Qain Special Learning Difficulties Training Center in the academic year of 1400-1399, the total number of these students was 20, which is a sample They were randomly placed in two experimental and control groups. Prepare worksheets in 20 different areas of psychological processes and the experimental group was trained for 20 sessions of 45 minutes, while the control group did not receive any training. To collect data, the processing speed subscale of the fourth edition of the Wechsler Intelligence Scale for children (Wechsler, 2003), the Iran KIMAT math test, and two tests developed by the researcher of the Mathematical Progress (Qorbanpour, 2019) were used. Data were analyzed using multivariate analysis of covariance. The obtained results showed a significant difference between the two experimental and control groups in the post-test. This means that education has been effective in improving the processing speed and math progress of students with math disorders. Based on the obtained results, paying attention to the educational strategies of basic psychological processes can lead to promising results in the education and rehabilitation of students with learning disabilities, and it can be used as an effective intervention method.
