Abstract:
The purpose of this study was to demonstrate the effect of similar faces in
mothers on facial attractiveness. The research selectively recruited 15 male college
student volunteers, whose ages ranging from 19 to 26, as participants, and followed a 2
[facial type: father or mother] ×2[similarity type: similar (55%) or not similar (45%)]
double-factor within-subject experiment design. The dependent factor indicators are:
(1) the reaction time for the participants to score the facial picture’s attractiveness; (2)
the attractiveness score the participants assign to the facial picture; (3) the average
amplitude of the ERP components (N100, N170, VPP, and P300). The results showed
that male college students rated the attractiveness of similar faces of their mothers
significantly higher than that of non-similar faces, and the response time was shorter.
At the same time, the study used the event correlation potential technique (ERPs) to
investigate the EEG indicators of the subjects’ behavioral responses. The results showed
that: (1) the amplitude of components VPP and P300 induced by faces similar to themother was significantly higher than that induced by faces not similar to the mother;
(2) in terms of N100, N170, VPP and P300 components, the mother's face type image
induced a stronger ERP effect than the father's face type image.
本研究旨在证明母亲相似面孔对面孔吸引力评价的影响:研究选取 15
名男大学生为被试,要求对母亲相似面孔、母亲不相似面孔、父亲相似面孔、
父亲不相似面孔,以及控制组的面孔照片进行面孔吸引力评价,记录其反应时
指标。结果显示:男大学生对母亲相似面孔的吸引力评价显著高于不相似面孔,
反应时也更短。研究同时运用事件相关电位技术(ERPs)考察被试做出行为反
应时的脑电指标,结果显示:(1)与母亲相似面孔诱发的 VPP、P300 成分的波
幅显著高于与母亲不相似的面孔;(2)在 N100、N170、VPP 和 P300 成分上,
母亲面孔类型图片比父亲面孔类型图片诱发出更强的 ERP 效应。
