| Outline of Final Research Achievements |
The present study investigated the influence of expectancy on neural and autonomic responses during the preparatory phase of exercise in healthy young adult males. Expectancy was manipulated through positive or negative feedback regarding participants' ability to cope with exercise-induced stress. The results indicated that individuals in the high-expectancy group, who received positive feedback, exhibited significantly increased activity in the left dorsolateral prefrontal cortex (DLPFC) and a more gradual rise in heart rate prior to exercise. Furthermore, a positive correlation between state anxiety and left DLPFC activity was only observed in the high-expectancy group. The findings suggest that enhanced expectancy may facilitate the brain's regulatory function in response to stress and help suppress excessive physiological arousal. This highlights the potential role of psychological factors in modulating stress-related neural and autonomic processes.

本研究は、運動ストレス課題における「期待感」が脳および自律神経の準備的反応に与える影響を明らかにし、ストレス応答の個人差に関する神経生理学的理解を深めた点で学術的意義がある。特に、左DLPFCの活動が期待感によって変化し、心拍数の上昇が緩やかになることを示した点は、ストレス調整機構の新たな知見である。また、状態不安とDLPFC活動の関連が期待感によって変化することから、心理的要因が神経応答に及ぼす影響を示唆した。これらの成果は、ストレス関連疾患の予防やメンタルヘルス支援において、期待感を高める心理的介入の有効性を示すものであり、教育・スポーツ・医療など多様な分野での応用が期待される。
