まとめ
ネガティブな感情は認知制御を損なう。特にワーキングメモリの更新と認知の柔軟性は損なわれるが、抑制は直接的には損なわれない。これらの効果は相互に関連しており、感情が実行機能をどのように異なる影響を与えるかを示している。
科学分野:
- 認知心理学
- 神経科学
- 感情科学
背景:
- 認知制御は目標指向行動に不可欠である。
- 抑制、更新、シフトを含む実行機能は、認知制御に不可欠である。
- これらの異なる実行機能に対するネガティブな感情の影響は、さらに解明される必要がある。
研究 の 目的:
- 抑制、更新、シフトに対するネガティブな感情の差次的な影響を調査すること。
- 様々な認知制御コンポーネントに対する感情関連効果間の相互関係を探求すること。
主な方法:
- 参加者は、中立的およびネガティブな感情状態下で、Go/No-Go、2-back、およびセットスイッチング課題を完了した。
- 各課題の反応時間と精度を測定した。
- 相関分析により、課題間の感情関連効果の関連性を調べた。
主要な成果:
- ネガティブな感情は、抑制課題における偽陽性反応を遅らせ、干渉が増加したことを示唆した。
- ネガティブな感情下では、ワーキングメモリの更新(2-back課題)の精度が低下した。
- シフト課題ではエラー率が高く、認知の柔軟性が損なわれていることが示唆された。
- 更新とシフトの間で感情に関連する効果が相関したが、抑制では相関しなかった。
結論:
- ネガティブな感情は、すべての実行機能を一様に影響するわけではない。
- 更新とシフトは、抑制よりもネガティブな感情干渉の影響を受けやすいようである。
- これらの発見は、感情と認知の複雑な相互作用を強調し、特定の実行機能を異なる影響を与える。

The Influence of Affect on Cognition
277
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect
200
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 Theories: Schachter-Singer Theory of Emotion
1.6K
Stanley Schachter and Jerome Singer proposed the two-factor theory of emotion, which emphasizes the interplay between physiological arousal and cognitive labeling in forming emotional experiences. This theory suggests that emotions are not simply a result of physiological responses but rather a combination of these responses and the individual's cognitive interpretation of them.

Cognitive Theories: Lazarus Mediational Theory of Emotion
2.1K
Richard Lazarus' cognitive mediational theory highlights the pivotal role of cognitive appraisal in shaping emotional responses. According to this theory, the evaluation of a stimulus — based on personal values, goals, beliefs, and expectations — mediates the emotional response. This appraisal process is immediate and often occurs unconsciously, influencing the intensity and nature of the resulting emotion.

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...

Physiology of Emotion

The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...
