概括
前带带皮质 (ACC) 可能无法调节注意力,而是检测信息处理冲突. 大脑成像显示,随着冲突水平的提高,ACC活动增加,支持冲突监测理论.
科学领域:
- 神经科学是一个神经科学.
- 认知神经科学 认知神经科学
背景情况:
- 前带带皮层 (ACC) 参与注意力调节,但其精确的认知作用仍在争论中.
- 现有的理论认为,ACC调解"行动选择"或监控处理冲突.
研究的目的:
- 区分ACC函数的"选择行动"和"冲突监测"理论.
- 研究ACC在认知控制中的作用.
主要方法:
- 功能磁共振成像 (fMRI) 用于测量大脑活动.
- 参与者执行了一个任务,旨在反过来操纵选择行动的强度和响应冲突.
主要成果:
- 在高冲突和弱选择为行动的试验中,ACC激活显著更高.
- 相反,在冲突较低和强烈的行动选择的试验中,ACC活动较低.
结论:
- 这些发现支持ACC函数的冲突监测假设.
- 该ACC似乎信号的发生的认知冲突,而不是直接行使注意力控制的行动选择.

Strategies of Self-Presentation III: Self-Monitoring
Self-monitoring is a central construct in understanding individual differences in self-presentation strategies across social contexts. It refers to how individuals observe, regulate, and control their expressive behavior and self-presentation following situational cues. Self-monitoring reflects a person's sensitivity to social appropriateness and willingness to adapt behavior to fit varying interpersonal demands.High vs. Low Self-Monitoring IndividualsIndividuals high in self-monitoring are...
The Influence of Cognition on Affect
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 interpreted as...
