Abstract

比較的大きな身体動作をともなう作業に対して,自分の物理的・精神的な状態をモニタリングする自己観察が有効であることが知られている.しかし,ごくわずかな身体動作しかともなわない認知的な作業に対する自己観察の有効性については,これまでほとんど検証されていない.そこで,本研究では,視認できないレベルの身体動作しかともなわない音声ストループ課題と,視認できるレベルのごくわずかな身体動作をともなう音声ストループ課題の2つの課題を用意し,被験者実験によって自己観察がこの両課題にどのような影響を与えるかを調査した.その結果,正答率についてはいずれの課題についても自己観察の影響が認められなかったが,反応時間については,視認可能な身体動作をともなう場合には時間短縮が認められたのに対し,身体動作を視認できない場合にはむしろ反応時間が長くなる傾向があることが明らかになった.

It has been known that self-observation of one's physical and mental condition is effective to improve performance of tasks with relatively large physical movement. However, it has not been investigated whether the self-observation of cognitive tasks only with minuscule physical movements is similarly effective. Accordingly, we conducted two experiments with subjects to investigate this problem. We prepared two acoustic stroop tasks: the first one is accompanying with only invisible level of body motion, and the second one is accompanying with very small level of visible body motion. Using these two acoustic stroop tasks, we investigated how the self-observation influences the performances of these tasks. As a result, as for the correct answer rate, the influence of the self-observation was not found for either task. However, as for the reaction time, a time reduction was observed when visible minuscule physical movements were accompanied with. In contrast, the reaction time tends to be prolonged when the body movement was not visible, and it was suggested that self-observation had a negative effect in this case.
