Reasoning on social dilemmas varying in emotional saliency: an adult developmental perspective.

The purpose of this study was to provide age-comparative evidence of social cognitive reasoning in adulthood, as mediated by the emotional saliency of tasks tapping postformal reasoning. Specifically, the tasks focused on the ability to resolve discrepant accounts of the same event sequence. It was assumed that less mature thinking may be more evident in reasoning contexts in which emotional factors play a major role. A postformal coding scheme was used to assess levels of reasoning in an interpersonal context. Tasks were administered to 60 subjects--adolescents and young and middle-aged adults. Measures of formal operations, ego level, and verbal ability were also administered. An interaction was found between age and degree of emotional saliency of the task for reasoning level. Specifically, adolescents performed less well on tasks higher in degree of emotional saliency. In addition, developmental differences in postformal reasoning as a function of age and ego level were found.
