Abstract
The purpose of this study is to determine the quality of individual economic decision making under risk and uncertainty. The research method is a quasi-experiment with single group and a post-test. The total population of the students of Shahid Beheshti University in 97 was 8.700 and due to non-normal distribution, we should use non-parametric Wilcoxon test, with sample of 180. The tool used to investigate the role of cognitive biases that prospect theory in economic decision-making was predicted was a multi-dimensional task we built which measured 31 problems in 5 sections that through phenomena such as risk aversion, loss aversion, ambiguity aversion, reference dependency, probability weighting and so on in shows irrationality in economic decision–making. Higher score means more irrational according to neoclassical economics. The median of scores was 25 out of 31 scores. In other words, more than 80% of participants received grades above 50% (or 15.5 points) (p <0.05). These findings fully supported the prospect theory that first two cognitive psychologists proposed as a correction to the expected utility theory. The prospect theory can explain, and can predicts, and intends to dissolve the gap between economy and psychology. The present research is an initial step in showing the significant role of psychology and cognition in economic decision-making and emphasize the importance of psychology in explaining economic tendencies and findings especially in our country, as the founders of the economy have expressed many centuries ago.

Abstract
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.

Abstract
Psychologists have proposed two styles for thinking and processing information. Experiential system, which is automatic and non-verbal; And the Rational system, which is analytical and verbal. The aim of the present study was to evaluate the psychometric properties of the Rational- Experiential Inventory; and to find it's relationship with cognitive regulation of emotions. This cross-sectional study was performed by descriptive contextualization method. The statistical population consisted of all students of Islamic Azad and Sama Universities, Roodehen Branch, and 503 individuals were selected randomly via multi- period method and completed the Rational-Experiential Inventory (REI) and Cognitive Regulation of Emotions Questionnaire (Garnefski & Kraaij, 2006). Data were analyzed by exploratory factor analysis, Cronbach's alpha, and correlation coefficient. After analysis, four components were identified: Rational Ability, Rational Engagement, Experiential Ability, Experiential Engagement. The Cronbach's alpha coefficient was 0.682, 0.823, 0.695, 0.750, and the correlation coefficient in the retest was 0.79, 0.78, 0.73, and 0.76, respectively. In the validity of criterion, rational components had negative correlation with negative strategies of regulation of emotions, and the experiential components had positive correlation with these strategies. The rational- experiential inventory showed proper reliability and convergent validity, In general, Rational people used positive emotion regulation strategies more and negative strategies less. The Rational- Experiential Inventory had adequate reliability and convergent validity. It can be used to improve the teaching, and psychotherapy.
