摘要知觉控制是一种基本的心理功能，它既可以促进积极情感，也可以缓冲消极情感。目前的研究解决了电生理相关的感知控制，行使的选择，在处理反馈价。36名参与者进行了EEG选择任务，在此期间，他们收到积极或消极的反馈，无论是由自己或由计算机做出的选择。知觉控制导致了增强的奖励积极性的积极反馈，但增加θ功率的负反馈。此外，感知控制导致更大的反馈P3振幅和Δ功率，无论反馈效价。这些结果表明，功能异质性的感知控制在反馈处理不同的放大奖励信号，提高控制的需要和增加的动机显着性的结果，无论效价。
Abstract Perceived control is a fundamental psychological function that can either boost positive affect or buffer negative affect. The current study addressed the electrophysiological correlates underlying perceived control, as exercised by choice, in the processing of feedback valence. Thirty-six participants performed an EEG choice task during which they received positive or negative feedback following choices made either by themselves or by a computer. Perceived control resulted in an enhanced reward positivity for positive feedback but increased theta power for negative feedback. Further, perceived control led to greater feedback P3 amplitude and delta power, regardless of feedback valence. These results suggest functional heterogeneity of perceived control in feedback processing as diverse as magnifying the reward signal, enhancing the need for control and increasing the motivational salience of outcome irrespective of valence.
