表情、視線、観察者の性格が顔認知に与える影響 Influence of facial expressions, gaze direction, and social anxiety on memory of unfamiliar faces 菊谷, まり子 86550 60707412 本研究では、笑顔と怒り顔では笑顔のほうが記憶に残りやすいという先行研究に基づき、86名の大学生に笑顔と怒り顔を記憶してもらい、後に真顔で呈示されたそれらの顔を再認してもらう実験を行った。参加者の社会不安の程度を質問紙で図り、人と関わるときに感じる不安の程度が顔記憶に及ぼす影響も調べた。結果、社会不安が高い人達の間では怒り顔の再認率が笑顔の再認率より低かったが、低群では両表情の再認率に差はなかった。社会不安の高い人達は脅威を与える刺激に敏感で、怒り顔の表情の分析に注意力を注いだために、個人を特定するために必要な顔の普遍的な特徴を十分に分析できず、怒り顔の再認率が低下したと考えられる。 This research investigated memory of unfamiliar faces and how it is influenced by facial expression, direction of gaze, and observers’ level of social anxiety (SA). 86 participants were initially asked to view and memorize images of faces displaying either happy or angry expressions with direct or averted gaze. In the subsequent recognition phase, those previously shown faces and additional distractor faces were displayed with neutral expressions, and participants judged if they had seen them before. Participants were divided into high or low SA groups. Regardless of gaze, recognition for faces studied with angry expressions was significantly less accurate than for those studied with happy expressions, and this tendency was present only for individuals with higher levels of SA. The finding suggests that those individuals experienced elevated vigilance for threatening features of angry expressions, which may have disrupted their processing of identity-relevant features of the faces. 研究課題/領域番号:25885100, 研究期間(年度):2013-08-30 - 2015-03-31 出典：研究課題「表情、視線、観察者の性格が顔認知に与える影響」課題番号25885100 （KAKEN：科学研究費助成事業データベース（国立情報学研究所）） （https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-25885100/25885100seika/)を加工して作成 金沢大学国際基幹教育院GS教育系 / 同志社大学 research report 2015-06-09 AM application/pdf 平成26(2014)年度 科学研究費補助金 研究活動スタート支援 研究成果報告書 2013-08-30 - 2015-03-31 5p. 2014 Fiscal Year Final Research Report https://kanazawa-u.repo.nii.ac.jp/record/48643/files/GS-PR-KIKUTANI-M-kaken 2015-5p.pdf https://doi.org/10.24517/00054965 http://hdl.handle.net/2297/00054965 https://kanazawa-u.repo.nii.ac.jp/records/48643 jpn https://kaken.nii.ac.jp/search/?qm=60707412 https://kaken.nii.ac.jp/search/?qm=60707412 https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25885100/ https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-25885100/ https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-25885100/25885100seika/ https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-25885100/25885100seika/
