SPECIFIC EFFECTS OF ANGER RUMINATION ON PARTICULAR EXECUTIVE FUNCTIONS (.).

The effects of two types of rumination on different kinds of executive functions were investigated. Fifty-nine participants (M age = 22.8 yr., SD = 2.5) were assigned to one of three conditions and instructed either to: (1) ruminate in a self-distanced way, (2) ruminate in a self-immersed way, or (3) think about the layout of their campus following anger induction. Afterward, the participants were directed to finish tasks designed to assess three kinds of executive functions: shifting, inhibition, and updating. Results showed that self-immersed rumination impaired shifting ability the most, while participants engaged in self-distanced rumination showed the worst performance on the inhibition task. No significant difference was found in the updating task. These results suggest that rumination influenced particular executive functions in different ways.
