Abstract

The present EEG study with 32 healthy participants investigated whether affective knowledge about a person influences the visual awareness of their face, additionally considering the impact of facial appearance. Faces differing in perceived trustworthiness based on appearance were associated with negative or neutral social information and shown as target stimuli in an attentional blink task. As expected, participants showed enhanced awareness of faces associated with negative compared to neutral social information. On the neurophysiological level, this effect was connected to differences in the time range of the early posterior negativity (EPN)—a component associated with enhanced attention and facilitated processing of emotional stimuli. The findings indicate that the social-affective relevance of a face based on emotional knowledge is accessed during a phase of attentional enhancement for conscious perception and can affect prioritization for awareness. In contrast, no clear evidence for influences of facial trustworthiness during the attentional blink was found.

一见钟情前的不信任？检验基于知识和外观的可信度对人脸视觉意识的影响

本项脑电图研究以 32 名健康参与者为对象，调查了对一个人的情感认知是否会影响对其面部的视觉认知，同时还考虑了面部外观的影响。根据外貌感知可信度不同的人脸与负面或中性的社会信息相关联，并在注意力眨眼任务中作为目标刺激显示出来。不出所料，与中性社会信息相比，受试者对与负面社会信息相关的面孔表现出更强的意识。在神经生理学层面上，这种效应与早期后负性（EPN）时间范围的差异有关--EPN 是一种与注意力增强和情绪刺激处理促进有关的成分。研究结果表明，人脸的社会情感相关性是基于情感知识，在有意识感知的注意增强阶段获得的，并能影响意识的优先级。与此相反，在注意闪烁期间，没有发现明确的证据表明人脸的可信度会产生影响。

期刊介绍： Consciousness and Cognition: An International Journal provides a forum for a natural-science approach to the issues of consciousness, voluntary control, and self. The journal features empirical research (in the form of regular articles and short reports) and theoretical articles. Integrative theoretical and critical literature reviews, and tutorial reviews are also published. The journal aims to be both scientifically rigorous and open to novel contributions.
