ネガティブな反すう傾向と怒りの関連 : 怒りの認知，感情，行動に関する検討

The purpose of this study was to examine the relationship between the
negative rumination trait (NRT) and anger expression as well as examining
an influence of the NRT on cognitive and emotional aspects of anger in anger
provoking situation. In the experiment, the 18 participants were male
undergraduate students. The NRT scale was used to assess the NRT. The
participants were divided into two groups (high NRT, low NRT) based on
each participants’ score of the NRT scale. An anger provoking situation
which was a recorded conversation was presented to the participants. Then,
state anger levels and automatic thoughts were measured during anger
provoking situations.
Results of this study showed that no difference of anger expression and
state anger reduced significantly during rumination regardless of high or low
NRT. Moreover, automatic thoughts in the anger provoking situations were
analyzed using text mining. Result of text mining indicated that the low
NRT group judged the situation in an objective perspective. In contrast, the
high NRT group set up automatic thoughts about induced-anger and
judgments on their situations. From these results, while there was no
difference in the duration of state anger, it was suggested that participants
had potential to ruminate in cognitive aspects.
