To investigate Brain Waves of Impulsivity individuals in Cognitive Task

The purpose of study was to determine the brain waves of subjects with impulsivity trait in performing cognitive task. 140 female students who completed the Revised Eysenck Personality Questionnaire, after control of the inclusion criteria, two groups of 20 people, including high impulsive (Imp) and low impulsive (Imp-) were selected. The subjects in two status: (a) resting (without doing the task); and (b) performing a cognitive task (Wisconsin test), taking EEG. The Results showed, when performing a cognitive task, activity of the prefrontal, frontal, and temporal areas of both hemispheres increased significantly in Imp. Alpha and Theta wave showed that during cognitive task, the activity of all regions of both hemispheres in Imp was greater than Imp-. About Beta wave, the results indicated that the left prefrontal, temporal and the right frontal was more activated in Imp than the other group. The results emphasize to consider personality traits when examining the brain regional activity, as well as investigate of the functional impulsivity and its differentiation with dysfunctional impulsivity .
