자아고갈과 폭식수준이 충동행동에 미치는 영향

초록

The goal of this study is to identify the effect of ego-depletion on impulsive behavior according to the level of binge eating. 100 participants were categorized into two groups (high and low binge group) by using binge eating scale and the Korean version of eating attitude test-26. Participants were randomly assigned to two different tasks: Ego-depletion task of depleting cognitive resources by lowering self-control through cognitive overload; non-depletion task without cognitive overload. Impulsive behavior of participants was measured by a computerized stop signal task that presented object cues and food cues. The results showed no significant difference between the groups in the non-depletion task but low binge group took longer time to suppress impulsive response to food cues than high binge group in ego-depletion task, indicating that the task affected the impulsive behavior of low binge group on food cues more than high binge group. These results could demonstrate that low binge group would increase the impulsive behaviors when they consume more cognitive resources related to self-control than high binge group.
