利用事件相关电位，我们研究了大脑如何从他人面部提取信息并将其实时转化为相关动作。在研究 1 中，参与者对典型性别和非典型性别面孔进行了双手之间的性别分类。非典型性别面孔在 250-550 毫秒之间引发消极情绪（N300/N400 效应），反映了将积累的性别类别知识整合到连贯的性别类别解释中。此外，侧化准备电位（LRP）显示，运动皮层开始为正确的手部反应做准备，而社会类别知识仍在逐渐并行发展。在研究 2 中，参与者根据目标性别对双手之间的眼睛颜色进行分类，作为进行/不进行试验的一部分。在禁行试验中，尽管手实际上没有移动，但有关眼睛颜色的信息部分准备了运动皮层，以便在性别感知最终确定之前移动手。总之，这些发现证明了人的感知和行动之间的动态连续性，使得面部处理的持续结果随着时间的推移立即连续地级联到运动系统中。在感知者完成对他们刚刚看到的内容的解释之前，行动的准备就开始于对他人面部的初步感知。
Using event-related potentials, we investigated how the brain extracts information from another’s face and translates it into relevant action in real-time. In Study 1, participants made between-hand sex categorizations of sex-typical and sex-atypical faces. Sex-atypical faces evoked negativity between 250-550 ms (N300/N400 effects), reflecting the integration of accumulating sex-category knowledge into a coherent sex-category interpretation. Additionally, the lateralized readiness potential (LRP) revealed that the motor cortex began preparing for a correct hand response while social category knowledge was still gradually evolving in parallel. In Study 2, participants made between-hand eye-color categorizations as part of go/no-go trials that were contingent on a target’s sex. On no-go trials, although the hand did not actually move, information about eye color partially prepared the motor cortex to move the hand before perception of sex had finalized. Together, these findings demonstrate the dynamic continuity between person perception and action, such that ongoing results from face processing are immediately and continuously cascaded into the motor system over time. The preparation of action begins based on tentative perceptions of another’s face before perceivers have finished interpreting what they just saw.
