概括
背叛通过降低注意力处理效率来削弱对负面刺激的执行控制. 这种效应主要与情绪环境中的反应性控制有关,而不是主动性控制.
科学领域:
- 认知神经科学 认知神经科学
- 社会心理学 社会心理学
- 神经科学是一个神经科学.
背景情况:
- 众所周知,背叛会增加负面的注意偏差,并损害执行控制.
- 控制模型的双重机制假定执行控制包括反应性和主动性控制.
- 背叛如何在情感背景下具体调节执行控制,目前尚不清楚.
研究的目的:
- 调查背叛对执行控制情绪调节的影响.

Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...
