まとめ
値以下うつ病 (STD) は,特に目と口の動きにおけるポジティブな表情の低下と関連しています. しかし STDは観察者の個人に対する最初の印象を 大きく変えてくれませんでした
科学分野:
- 心理学
- 神経科学
- コンピュータ科学
背景:
- うつ病は 顔の表情や感情の認識に 変化が伴うものです
- 潜在的プロドロマの段階であるサブスリーブレベルうつ病 (StD) は,同様の顔の変化を調査する必要があります.
研究 の 目的:
- 値以下うつ病 (STD) が表情や観察者の印象に影響するかどうかを調査する.
- 性病に関連した特定の顔の動きパターンを特定する.
主な方法:
- 日本人の大学生を紹介する 10秒のビデオを録音した
- 主観的な印象評価を集め ベックうつ病インベントリーII (BDI-II) を実施した.
- 顔の動作 (AU) を定量化するために自動顔分析 (OpenFace 2.0) を利用しました.
主要な成果:
- STD (BDI-II 11-20) 患者の割合は,健康な対照群 (BDI-II 1-10) と比較して,かなり低いポジティブ表現性スコア (表現的,自然,フレンドリー,好ましい) を示した.
- 自動化された分析により,性病の患者で眉を上げて口を動かすことに関連した特定のアクションユニット (AU) の存在/強度が増加したことが明らかになった.
- 5つのAUは,偽発見率をコントロールした後にBDI-IIスコアと有意に相関していた.
結論:
- 値以下うつ病の特徴は 顔の表情が鈍くなり 眼と口の動きがはっきりします
- 性病の顔のサインは 観察者の最初の判断に 偏りがあるように見えません
- 特定されたAUパターンは,臨床的うつ病のリスクのある個人の早期発見に役立ちます.
