Abstract:

The aim was to assess decision-making in adolescents. To this, we used the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT). We used an experimental design with pre-post-test where we manipulated the treatment (Intoxicated/Non Intoxicated) and the information received (True/False). 73 volunteers were evaluated between 18 and 25 years old. Data was analyzed using ANOVA. We found differences between men and women in different scores on the IGT and GDT. Sex-related effects of the participants agreed with other studies. The better performance of women on the GDT can be explained taking into account that executive functions are involved in task execution, at which women perform better. Finally, results related to intoxication suggest that alcohol affects the quality of decision making.
