概括
情绪显著影响反应抑制 (RI),但结果因停止信号反应时间 (SSRT) 的计算方式而异. 这项研究强调,SSRT估计的平均方法不可靠,应避免在情绪-RI研究中使用.
科学领域:
- 认知神经科学 认知神经科学
- 情感科学是一种情感科学.
- 心理学 心理学 心理学
背景情况:
- 情绪和响应抑制 (RI) 相互作用是复杂的,现有文献中存在矛盾的发现.
- 停止信号反应时间 (SSRT) 计算方法的可变性可能解释不一致的结果.
- 以前的研究往往缺乏可靠的SSRT估计,可能会损害情绪-RI相互作用发现的可靠性.
研究的目的:
- 调查不同的SSRT估计方法如何影响情绪操纵对反应抑制的观察效应.
- 确定SSRT计算的选择是否会影响认知控制中的情感相关调制的检测.
- 为未来的情绪和RI研究提供可靠SSRT估计的建议.
主要方法:
- 利用了停止信号任务的情感变体,使用情感面孔作为启动刺激.
- 通过不公平的惩罚诱导负面情绪来操纵影响和动机.
- 使用平均值方法对比SSRT估计与整合方法的两个变体.
主要成果:
- 只有使用平均SSRT估计方法时,才观察到情绪操纵对RI的显著影响.
- 对SSRT估计的整合方法没有显示出情绪的显著影响.
- 平均方法似乎高估了SSRT,可能导致虚假的发现.
结论:
- 选择SSRT估计方法极大地影响了关于情绪-RI相互作用的结论.
- 平均SSRT估计方法对于研究情绪和RI是不可靠的,应该避免使用.
- 建议在未来的研究中采用整合方法,考虑参与者战略在有努力的控制环境中.

Cognitive Theories: Schachter-Singer Theory of Emotion
270
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.

Coping Strategies: Emotion Focused
55
Emotion-focused coping refers to a set of strategies aimed at managing the emotional impact of stressors, rather than directly addressing their causes. This approach involves altering one's emotional response to stressful situations to reduce their psychological effects. For example, individuals might talk with a friend or engage in activities like journaling to express their feelings. Such actions can help achieve emotional clarity or release, providing the psychological stability needed...
