ثمینه موسوی زاد

The purpose of this research is to investigate the effect of acute stress on interpretation and decision-making in social situations and the moderating role of stress of life events on people. This research is a quasi-experimental study and the analysis method is a factorial design. The data obtained from this research was collected by available sampling method from ۶۳ men and women in the age group of ۱۸ to ۵۵ years. The data collection tool was a questionnaire. People completed Sarason's stressful life events questionnaire and then were divided into experimental and control groups. After the experimental groups were subjected to the acute stress test, they were subjected to the challenges of interpreting ambiguous faces and the prisoner's dilemma decision game. The data obtained from the research was analyzed through    ۲۶ statistical software. The findings indicated that people who had experienced more negative stressful events in their lives had a significantly more negative interpretation of ambiguous faces in the presence and absence of acute stress. However, no significant relationship was found between stressful life events in the presence and absence of acute stress and decision making. Therefore, people who experience negative stressful events in their lives show bias in information processing and interpret emotional ambiguities in a threatening direction. This issue is exacerbated by acute daily stress.
