Outline of Final Research Achievements |
Attention is one of the main cognitive functions responsible for information selection and is directed towards physically salient attributes and objects that are consistent with the mental situation. The present study investigated attention bias, a condition in which attention is more likely to be directed to situations and objects related to an anxious state. Study 1 examined whether gastrointestinal symptom-related words are more attentive than negative words to subjects with a tendency towards irritable bowel syndrome (IBS). Individuals with high state anxiety were found to be routinely attentive and alert to gastrointestinal symptom-related words. Study 2 examined the effect of the internet-based attention bias modification method (iABM) on reducing anxiety among general workers.

Academic Significance and Societal Importance of the Research Achievements |
注意バイアス測定法の研究は精神疾患の理解,状態の改善に貢献しうる。特に研究2の成果は,介入群における反応時間が改善されたことを示している。この事実は、介入群における者の注意バイアスが正常化したことを意味する可能性がある。また、介入群で状態不安が有意に低下したことから、本研究で開発したiABMがマイルドな不安の軽減に寄与することが示唆される。注意バイアスは不安症状やうつ症状などの精神疾患に関連しているため,今後の研究によって,注意バイアスがどのように病態の発症や維持に影響を与えるかを理解することに貢献するだろう。
