我们遵循ERP为基础的方法来获得知识的依赖性和时间顺序的两个基本过程的面孔知觉：吸引力和性别。通过结合双选择任务和go/nogo范式的LRP和N200效应，我们可以估计这两种类型的面孔加工的加工时间和启动。LRP的分析显示，性别方面的处理比吸引力早得多。而性别已经分析了243.9毫秒后刺激发作，吸引力开始发挥作用58.6毫秒后，即后刺激发作延迟302.5毫秒。这一结果的模式是反映了分析的N200效应，主要是正面的效果，这是应该与抑制不适当的反应。以N200效应的开始作为信息已经被充分处理以进行任务决策的时刻的估计量，我们可以在152.0 ms处追踪N200效应，用于性别的go/nogo决策，而不是早在206.7 ms的吸引力。总而言之，面部吸引力的处理似乎是基于性别特异性的审美预处理，例如通过激活性别特异性吸引力原型，这些原型显示出对某些面部方面的集中处理。
We followed an ERP-based approach to gain knowledge on the dependence and temporal order of two essential processes of face perception: attractiveness and gender. By combining a dual-choice task with a go/nogoparadigm focusing on the LRP and N200-effect, we could estimate the processing times and onsets of both types of face processing. The analyses of the LRP revealed that gender aspects were processed much earlier than attractiveness. Whereas gender was already analysed 243.9 ms post-stimulus onset, attractiveness came into play 58.6 ms later, i.e. after a post-stimulus onset delay of 302.5 ms. This resulting pattern was mirrored by the analyses of the N200-effect, an effect available mainly frontally which is supposed to correlate with the inhibition of inappropriate responses. Taking the onset of the N200 effect as an estimator for the moment at which information has been processed sufficiently for task decision, we could trace the N200 effect at 152.0 ms for go/nogo-decision on gender, while not as early as 206.7 ms on attractiveness. In sum, processing of facial attractiveness seems to be based on gender-specific aesthetic pre-processing, for instance via activating gender-specific attractiveness prototypes which show focused processing of certain facial aspects.
