Abstract
The aim of the present study was to investigate prospective and retrospective memory and cognitive ability in three groups of personality based on reinforcement sensitivity theory. For this purpose, first, 358 students Bu Ali Sina university were selected through a multistage cluster sampling. Then Brain / behavioral Systems questionnaire were distributed among them to be answered. After initial data analysis, 51 of them, based on cluster analysis in Brain / behavioral Systems questionnaire were selected, in order to test the hypothesis of this study, participants were studied in dimensions of prospective and retrospective memory and cognitive ability. The collected data were analyzed using descriptive indicators, multivariate analysis of variance and post hoc tests. Results showed significant difference between three personality groups in memory and cognitive ability. So that, group with high behavioral inhibition system sensitivity have better performance in components of retrospective memory, prospective memory, general memory and ability of naming; group with high sensitivity of fight-flight-freeze system have higher scores in prospective memory and general memory. The results showed that more active and less active of brain/ behavioral systems may be in close relation with memory and other cognitive abilities. It seems that cognitive abilities can to be influenced by the brain systems associated with reinforcement sensitivity and thereby cognitive functions changed.

Abstract
The present study investigated the effect of attention and memory training and improvement software on cognitive ability and emotion regulation in patients with corona virus after recovery. The present research project is a pre-test-post-test experiment with a control group. The statistical population of this research included all the residents of Shadegan city who were hospitalized in the first half of 2021 due to the corona virus in Shahid Moarefi Zadeh hospital (exclusively for corona patients) and then recovered. According to the research design, the sample size was 40 people, who were placed in 2 groups of 20, test and control groups (20 people in test group and 20 in control group) and were selected by simple random sampling method and randomly placed in test and control groups. Also, only the test group was intervened with attention and memory training and improvement software, and finally both groups answered the questionnaires (post-test) again. The research tools were the Garnefski`s Cognitive Emotion Regulation Questionnaire, Nejati`s Cognitive Capability Questionnaire, and attention and memory training and improvement software. Also, descriptive statistics such as mean and standard deviation, minimum and maximum scores and inferential statistics such as; Levene test and covariance analysis were used to analyze data using SPSS software version 24. The results of covariance analysis of the data have shown that there was a significant difference between the experimental and control groups in each of the dependent variables (P<0.001). That is, the average of the cognitive regulation of emotion and cognitive ability and all the components of these two variables have increased significantly in the experimental group compared to the pre-exam and the control group. Therefore, it can be said that the attention and memory training and improvement software has had a significant impact on the cognitive ability and emotion regulation of recovered patients of corona virus.
