Abstract

We cannot see the minds of others, yet people often spontaneously interpret how they are viewed by other people (i.e., meta-perceptions) and often in a self-flattering manner. Very little is known about the neural associations of meta-perceptions, but a likely candidate is the ventromedial pFC (VMPFC). VMPFC has been associated with both self- and other-perception as well as motivated self-perception. Does this function extend to meta-perceptions? The current study examined neural activity while participants made meta-perceptive interpretations in various social scenarios. A drift-diffusion model was used to test whether the VMPFC is associated with two processes involved in interpreting meta-perceptions in a self-flattering manner: the extent to which the interpretation process involves the preferential accumulation of evidence in favor of a self-flattering interpretation versus the extent to which the interpretation process begins with an expectation that favors a self-flattering outcome. Increased VMPFC activity was associated with the extent to which people preferentially accumulate information when interpreting meta-perceptions under ambiguous conditions and marginally associated with self-flattering meta-perceptions. Together, the present findings illuminate the neural underpinnings of a social cognitive process that has received little attention to date: how we make meaning of others' minds when we think those minds are pointed at us.

摘要

我们无法看到他人的思维,但人们经常自发地(即元知觉)解释他们在他人眼中的形象,而且往往是自夸的方式。关于元知觉的神经关联知之甚少,但一个可能的候选者是腹内侧前额叶皮层(VMPFC)。VMPFC 与自我和他人知觉以及有动机的自我知觉都有关。这种功能是否延伸到元知觉?本研究在参与者在各种社会场景中进行元知觉解释时,检查了神经活动。使用漂移扩散模型来测试 VMPFC 是否与解释自夸的元知觉的两个过程有关:解释过程中涉及有利于自夸解释的证据的优先积累的程度,以及解释过程开始时有利于自夸结果的程度。当人们在模棱两可的情况下解释元知觉时,VMPFC 活动的增加与人们优先积累信息的程度有关,并且与自夸的元知觉有轻微关联。总的来说,这些发现阐明了一个社会认知过程的神经基础,迄今为止,这个过程很少受到关注:当我们认为他人的思维指向我们时,我们如何理解他人的思维。
