Predictors of Different Types of Decision-Making in Adolescence
The present study compared the performance of adults and adolescents on two types of decision-making tasks (intuitive vs. deliberative), as well as a number of psychosocial variables, to investigate whether different factors may predict different types of decision-making. Participants were divided into three groups: young adolescents (13-15 yrs), older adolescents (16-17 yrs), and adults (19 + yrs). The Iowa Gambling Task (IGT) measured intuitive based decision-making and a recent decision description task measured deliberative based decision-making. Results indicated a relationship between age with both decision-making tasks, as well as emotion regulation. As hypothesized, deliberative decision-making was predicted by future oriented thinking, independent of age. Intuitive decision-making ‘under ambiguity’ was predicted by age and sensation seeking. These results provide evidence of the existence of different types of decision-making and the idea that different factors predict each type.
