Abstract

Prior research on personality and decision-making has failed to use adequate measurement of both constructs. The current research extended the previous literature by incorporating multiple measures of decision-making as well as the NEO-PI-3, a psychometrically sound measure of the five-factor model of personality. Five measures of decision-making were used which addressed various aspects of adequate decision-making. The current research also included a measure of cognitive ability (WAIS-IV Vocabulary) as previous research has noted a strong correlation between cognitive ability and decision-making. Results indicated that cognitive ability significantly predicted performance on three decision-making tasks. In regard to personality, Agreeableness was the only personality trait found to be a significant predictor of any decision-making tasks.
