まとめ
うつ病は,個人が他者の信頼性についての信念を更新する方法に悪影響を及ぼし,明示的な信頼に対する一般的バイアスを示すが,ネガティブな社会的情報を処理する際に文脈特有の計算の不柔軟性を示す.
科学分野:
- コンピューティング精神医学は,計算精神医学である.
- ソーシャル・コग्निションとは
- 神経科学は神経科学である.
背景:
- うつ病は,社会的認知と意思決定の変化と関連しています.
- うつ病における信条更新の欠陥を理解することは,標的を絞った介入に不可欠です.
研究 の 目的:
- 鬱病の症状が,異なる社会的文脈における信頼性に関する信念の更新にどのように影響するか調査する.
- 鬱病における社会的認知障害の基礎にある計算メカニズムを特定する.
主な方法:
- 改変された信頼ゲームを使用して,計算心理学のアプローチを採用しました.
- 信頼性の高いパートナー条件と信頼性の低いパートナー条件を問わず,169人の参加者における明示的な信念レポートと暗黙の計算プロセスを評価しました.
主要な成果:
- より高いうつ病スコアは,より低い後部信頼信念を予測し,一般的なネガティブな更新バイアスを示しました.
- コンピューティングモデリングは,文脈に依存する確率バイアスを明らかにし,うつ病の症状は,信頼性の低い状態でのバイアスの減少に関連しています.
- 鬱病のスコアは,信頼性の低い条件においてのみ,協力性の低下と相関していた.
結論:
- 発見は,うつ病の解離を明らかにします:文脈特有の暗黙のバイアスとともに,広範囲にわたる否定的な明示的な信念.

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Self-Discrepancy and Its Effects
341
Self-discrepancy theory explains how people compare their actual self to their ideal and ought selves and how mismatches between these self-guides can lead to emotional distress. Developed by E. Tory Higgins, the theory distinguishes among three components of self-concept: the actual self, the ideal self, and the ought self. These refer respectively to how individuals perceive themselves, how they aspire to be, and how they believe they are obligated to be. Emotional well-being, self-esteem,...

The Influence of Cognition on Affect
241
Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Cognitive Therapy
1.3K
Cognitive therapy, pioneered by Aaron T. Beck in the 1960s, is a structured approach to addressing psychological distress by focusing on the influence of thoughts on emotions and behaviors. All cognitive therapies involve the basic assumption that human beings have control over their feelings, and that how individuals feel about something depends on how they think about it. Unlike psychoanalytic methods that delve into unconscious processes or humanistic approaches emphasizing...

Stereotypes, Prejudice, and Discrimination
95.6K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...
