When people want to make an emotional decision, they may avoid information that can make a rational decision stronger. With the aim of investigating information avoidance as a strategy to facilitate emotional decisions and in an experimental design, a call for participation in this study was sent to thirty thousand mobile phone subscribers in Tehran and Karaj and finally 383 people (149 men) with a mean age of 32 years participated in this research. First, participants were faced with rational and emotional choices, and then their information avoidance was measured. Participants were then randomly assigned to three groups and were given the same information they had avoided in three different ways. Finally, participants chose one of the two options and their desire for emotional choice was measured. Z Test and logistic regression analysis showed that most of the participants avoided information, but the same information affected their decisions, the participants who avoided information, chose more emotional choices, and the more the participants desire for emotional choice, the more their information avoidance. So, people avoid information to make emotional decision making easier.

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.

The three principles of double effect, personal contact, and action are suggested as the chief psychological mechanisms affecting human moral decision making in trolley dilemmas. The purpose of current research was to investigate the claim of the universality of these principles and their role in moral decision making in trolley dilemma in the oriental culture of Iran. In this research, using a semi-experimental single group pre-test-post-test design, four scenarios were used adopted from similar research. The statistical population of this research was the general population active in social media. The sample consisted of 235 participants with an average age of 30.34. Among the subjects, 143 were women and 92 were men. "McNemar" test was used for statistical analysis. Based on the results, the effect of all three principles on the ethical decision making of the subjects in trolley dilemma was confirmed significantly (Pvalue>0.05). Therefore, this research shows that all three principles of personal contact, action, and double effect are effectively influencing moral decision making.
