摘要

监管焦点理论(RFT)假设了个人目标追求的两个认知-动机系统:与理想目标(个人的希望、梦想和抱负)相关的促进系统,以及与应然目标(个人的职责、责任和义务)相关的预防系统。行为学研究对这两个系统进行了广泛的研究,涉及促进目标和预防目标追求之间的差异,以及在每个系统中实现与不实现目标的后果。然而,还没有研究对目标领域和目标实现状况的每种组合的神经相关性进行过研究。我们使用了一种快速掩蔽特异性目标引物范式和功能性磁共振成像技术来呈现单独选定的促进和预防目标,参与者之前曾报告说他们接近实现("匹配")或远未实现("不匹配")这些目标。在四种引物条件下,双侧岛叶(布罗德曼区(BA)13)和视觉联想皮层(BA 18/19)都出现了显著激活。促进引物显著地激活了左侧前额叶皮层(BA 9),而预防引物则显著地激活了右侧前额叶皮层(BA 8/9)。对晋升目标引物的激活反应还与晋升目标实现成功感的个体差异测量相关。我们的研究结果表明,在实现和未实现晋升目标的条件下,晋升目标引物所假设的两个系统具有共同而又不同的神经相关性,这与已建立的自我调节认知网络模型在逻辑上是一致的,从而扩展了晋升目标引物的建构有效性。

Neural signatures of promotion versus prevention goal priming: fMRI evidence for distinct cognitive-motivational systems.

Regulatory focus theory (RFT) postulates two cognitive-motivational systems for personal goal pursuit: the promotion system, which is associated with ideal goals (an individual's hopes, dreams, and aspirations), and the prevention system, which is associated with ought goals (an individual's duties, responsibilities, and obligations). The two systems have been studied extensively in behavioral research with reference to differences between promotion and prevention goal pursuit as well as the consequences of perceived attainment versus nonattainment within each system. However, no study has examined the neural correlates of each combination of goal domain and goal attainment status. We used a rapid masked idiographic goal priming paradigm and functional magnetic resonance imaging to present individually selected promotion and prevention goals, which participants had reported previously that they were close to attaining ("match") or far from attaining ("mismatch"). Across the four priming conditions, significant activations were observed in bilateral insula (Brodmann area (BA) 13) and visual association cortex (BA 18/19). Promotion priming discriminantly engaged left prefrontal cortex (BA 9), whereas prevention priming discriminantly engaged right prefrontal cortex (BA 8/9). Activation in response to promotion goal priming was also correlated with an individual difference measure of perceived success in promotion goal attainment. Our findings extend the construct validity of RFT by showing that the two systems postulated by RFT, under conditions of both attainment and nonattainment, have shared and distinct neural correlates that interface logically with established network models of self-regulatory cognition.
