Outline of Research at the Start

人間は他者の顔から性格や能力を判断する傾向を持つ。こうした顔に基づく対人印象(顔印象)はどの程度正確なのか。また、顔印象の正確性に関する人間の洞察(メタ認知)はどの程度正確なのか。本研究は、個人差に着目しながら、心理学実験を通じて以上の問いに答えることを目指す。第1に、「顔印象は正確である。」というメタ認知的信念を強く持つ人の顔印象は実際に正確なのか、或いは、何らかの偏りを含む不正確なものなのかを特定する。第2に、顔印象とそのメタ認知の正確性/偏りを生む心理過程の有力な候補として、顔知覚過程と学習・動機づけ過程の役割を検証する。

Outline of Final Research Achievements

People form impressions of other individuals’ personalities and abilities from their faces. This project examined the following two research questions regarding such facial impressions: 1) Do people who have a metacognition that facial expressions are accurate actually form accurate or biased facial impressions? 2) What accounts for individual differences in the accuracy and bias of facial impressions and metacognitions about them? For the first question, I found consistent evidence that the facial impressions formed by people with the metacognition that facial impressions are accurate are not necessarily accurate. While the results for the second question were unclear, I obtained interesting findings that the positive associations between fiction reading habits and social cognition may not be robust in Japan, and that people with the metacognition that facial impressions are accurate rely more on inappropriate facial cues, both of which merit further investigation in future research.

Academic Significance and Societal Importance of the Research Achievements

人間は他者の顔から性格や能力を判断し、その人に対する振る舞いを調整する傾向を持つ。このように対人認知・行動の重要な影響因である顔印象が正確であるのか、人間はその(不)正確性を正しく自覚できているのかを明らかにすることは、重要な研究課題である。本研究は、顔印象は正確だというメタ認知を持つ人の顔印象は実際には正確ではないこと、および、そもそも顔印象の正確性は安定した個人特性ではないことを新たに示した点で、学術的意義を有する。加えて、こうした実証的知見は顔印象が選挙、裁判、雇用などの重大な社会的意思決定に影響を与えている現状に警鐘を鳴らす点で、社会的意義を有する。
