Attractive faces have a special status, possibly because of evolutionary reasons. We assessed the automaticity of facial attractiveness processing in a dual-task paradigm manipulating the availability of cognitive resources to face processing by a primary tone task presented at varying stimulus onset asynchrony (SOA). In event-related brain potentials, attractive relative to neutral faces induced an increased posterior negativity from 260 ms onwards indicating enhanced stimulus encoding at the cortical level. Interestingly, effects of attractive faces on event-related brain potentials were most pronounced at high temporal overlap with the primary task (short stimulus onset asynchrony). This indicates that a shortage of cognitive resources may enhance the processing of attractive faces, revealing hard-wired processing biases of the human information processing system for evolutionarily prepared stimuli.
具有吸引力的面孔具有特殊地位，这可能是出于进化方面的原因。我们在一个双任务范式中评估了对面部吸引力进行加工的自动性，该范式通过以不同的刺激起始异步性（SOA）呈现的主音调任务来操纵用于面部加工的认知资源的可用性。在事件相关脑电位方面，相对于中性面孔，具有吸引力的面孔从260毫秒起诱发了增强的后部负波，表明在皮层水平上刺激编码得到增强。有趣的是，具有吸引力的面孔对事件相关脑电位的影响在与主任务的高时间重叠（短刺激起始异步性）时最为明显。这表明认知资源的短缺可能会增强对具有吸引力面孔的加工，揭示了人类信息处理系统对进化准备好的刺激的固有加工偏差。
