Research suggests that the exercise of control is desirable and adaptive, but the precise mechanisms underlying the affective value of control are not well understood. The study reported here characterized the affective experience of personal control by examining the neural substrates recruited when individuals anticipate the opportunity to make a choice--in other words, when they anticipate the means for exercising control. We used an experimental paradigm that probed the value of having a choice. Participants reported liking cues that predicted a future opportunity to make a choice more than cues that predicted no choice. The anticipation of choice itself was associated with increased activity in corticostriatal regions, particularly the ventral striatum, involved in affective and motivational processes. This study is the first direct examination of the affective value of having the opportunity to choose. These findings have important implications for understanding the role of perception of control, and choice itself, in self-regulatory processes.
研究表明,控制的行使是可取的和适应性的,但控制的情感价值背后的确切机制还不是很清楚。本研究通过考察个人在预期有机会做出选择时(换句话说,当他们预期有行使控制的手段时)所招募的神经基质,来描述个人控制的情感体验。我们使用了一种实验范式来探究拥有选择的价值。参与者报告说,他们更喜欢那些预示着未来有机会做出选择的线索,而不是那些预示着没有选择的线索。对选择的预期本身与皮质纹状体区域(特别是腹侧纹状体)的活动增加有关,腹侧纹状体涉及情感和动机过程。这项研究首次直接考察了有机会选择的情感价值。这些发现对于理解控制感和选择本身在自我调节过程中的作用具有重要意义。
