男性化与女性化对面孔偏好的影响——基于图像处理技术和眼动的检验

The Effects of Transformed Gender Facial Features on Face Preference of College Students:Based on the Test of Computer Graphics and Eye Movement Tracks

采用图像处理技术和眼动探讨了性别二态线索对面孔偏好的影响。实验1发现非面孔线索未掩蔽和掩蔽时,感知男性化技术与原始照片条件下女性化的男性面孔更有吸引力和信任度;性别二态技术条件下,非面孔线索未掩蔽时男性化的男性面孔更有吸引力和信任度。实验2表明被试对男性面孔的平均瞳孔大小和注视次数均大于和多于女性面孔,首次注视时间短于女性面孔;被试对男性化面孔的首次注视时间和首次注视持续时间均长于女性化面孔。

Perceived facial attractiveness can influence people＇s social interactions with one another, including mate selection, intimate relationship, hiring decision, and voting behavior. People evaluate faces using multiple trait dimensions such as attractiveness and trustworthiness both of which are affected by facial masculinity or femininity cues. However, studies manipulating the computer graphics of sexual dimorphism on facial attractiveness have yielded inconsistent results. Some found that feminine facial features in male faces were more attractive than masculine ones. Some others found that women prefer masculine male faces. And still others found that women preferred femininity in male faces. The current study used the computer graphics and the eye tracker to assess the effect of the dimorphic cues on the perception of facial attractiveness among Chinese college students through two experiments. Experiment 1 assessed women＇s perceptions of attractiveness and trustworthiness of men＇s faces under the condition of either perceived masculinity vs. femininity or the sexual dimorphism. Results showed that, when non-face cues （e.g., hairstyle） were masked, women perceived femininity in men＇s faces as more attractive and trustworthy than the masculinity. However, in the sexual dimorphism condition in which the non-face cues were not masked, women found masculinity in men＇s faces more attractive and trustworthy. Experiment 2 used the eye tracker to assess the effects of the dimorphic cues on the evaluation of facial attractiveness. Results showed that the subjects preferred the masculine male faces obtained by the sexual dimorphism and feminized female face. Eye movement tracking showed that average pupil dilation and average fixation count on a male face were significantly higher than on a female face. The first fixation time was significantly greater for the masculine faces than for the feminine ones, but the first fixation time was significantly shorter for the male faces than the female ones. The first fixation time and first fixation duration for masculine faces were both significantly longer than for feminine ones. These indicators of eye movement provide some evidence for the effect of the sexual dimorphism on the facial attractiveness.
