We review a program of research that has suggested that affective states high in motivationally intensity (e.g., enthusiasm, disgust) narrow cognitive scope, whereas affective states low in motivationally intensity (e.g., joy, sadness) broaden cognitive scope. Further supporting this interpretation, indices of brain activations, derived from human electroencephalography, suggest that the motivational intensity of the affective state predicts the narrowing of cognitive scope. Finally, research suggests that the relationship between emotive intensity and cognitive scope is bi-directional, such that manipulated changes in cognitive scope influence early brain activations associated with emotive intensity. In the end, the review highlights how emotion can impair and improve certain cognitive processes.
我们回顾了一个研究计划,该计划表明,动机强度高的情感状态(例如,热情、厌恶)会缩小认知范围,而动机强度低的情感状态(例如,喜悦、悲伤)则会扩大认知范围。进一步支持这一解释的是,来自人类脑电图的大脑激活指标表明,情感状态的动机强度预测了认知范围的缩小。最后,研究表明,情感强度和认知范围之间的关系是双向的,例如,认知范围的人为改变会影响与情感强度相关的早期大脑激活。最后,该综述强调了情绪如何损害和改善某些认知过程。
