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
| Making risky decisions in adolescents has become a major public health concern and understanding the correlations affecting this process makes it possible to implement prevention plans. Therefore, the present study was conducted to investigate the effect of positive and negative mood induction on risky decision-making by moderating high behavioral brain systems. In order to meet this aim, 327 adolescents aged 18-13 years in Isfahan were randomly selected and screened through the Behavioral Brain Systems Questionnaire (BAS / BIS). Based on the standard score, two groups of 24 participants including high BAS and BIS were selected. The members of each group were randomly divided into two equal subgroups, we induced positive mood in the first subgroup and negative mood in the second subgroup using Pieces of emotional movies. Participants completed the Balloon Risk Test (BART) and the Positive and Negative Emotion Scale (PANAS) before and after mood induction. Results of data analysis by univariate factor covariance analysis showed that there is a significant difference between inducing positive and negative mood on risky decision making (p≤ 0/05) and positive mood leads to increased risky decisions, The findings also showed that behavioral brain systems as biological personality traits significantly moderate the effect of mood induction on risky decision making (p≤ 0/05). This means that adolescents with a high behavioral activation system have more hyperactivity when faced with positive moods and they are more at risk than people with behavioral inhibition systems while adolescents with behavioral inhibition systems, on the other hand, are more sensitive to negative moods and signs of punishment and they are more cautious. |
