遂行機能が怒り喚起時の怒りの程度および行動抑制に及ぼす影響

The purpose of this study was to examine the influence of executive functions on the intensity of anger and on the inhibitory control over feelings of anger. The participants comprised 13 undergraduate students (6 males and 7 females). Measures used were the Behavioural Assessment of the Dysexecutive Syndrome (BADS) for executive functions, the trait and state anger scales for anger, and the go/no-go task for inhibitory control.
The participants were divided into two groups (high or low executive functions) on the basis of their average scores (± 1/2 SD) on the BADS. The participants were presented with anger-inducing situations that were made into recorded speech. Then, the anger levels within the presented situations and the inhibitory control that was exhibited after the situations were measured.
This study suggested that the average anger levels among the high executive functions group were lower than the anger levels of the low executive functions group. In addition, the anger levels after the go/no-go task were observed to be lower in the high executive functions group than in the low executive functions group.
These results suggest a difference in anger levels between the high and low executive functions groups in the same anger-inducing situations as well as after problem solving.
