Abstract

Dispositional optimism is considered a stable personality trait and as such may influence expectations about outcomes in a variety of decision-making scenarios.  The current study assessed the relationship between dispositional optimism and decision-making behavior when risk is present.  To investigate whether optimism was associated with risky decision-making behavior, we examined the relationships between dispositional optimism and two correlates (attributional style and trait hope) and risk-taking behavior on the Iowa Gambling Task (IGT) for 61 participants (Mage = 19.62).  Correlational analyses between the three measures of optimism and IGT performance indicate that dispositional optimism and risky decision-making behavior are not significantly related to one another.  This study contributes to the literature examining how individual differences influence decision-making.  A broader perspective on the factors that influence decision making is necessary so that the mechanisms that predict and explain risky decision making can be better understood.
