Previous studies have shown that individuals visually recognize their eye size as larger than the actual. However, it is unclear whether this cognitive tendency occurs in people with high self-face dissatisfaction. Therefore, this study aimed to investigate whether the cognitive size of one's own and others' eyes differs according to the degree of self-face dissatisfaction. Participants comprised 32 college students (5 males, 27 females; age: 21.3 ± 2.11) who completed the Face Dissatisfaction Scale (FDS) and a face recognition memory task. The task was to choose whether their or their friends' eyes in the face photos with changed eye size were larger or smaller than their actual eye size. The cognitively equivalent eye size to the actual one was estimated from a psychophysical function. We conducted a correlation analysis of the total scores on the FDS and the point of subjective equality (PSE) of eye size. We found a high negative correlation between the FDS and the PSE of own eye size. There was also a high positive correlation between the FDS and the PSE for all others' faces. Thus, high self-face dissatisfaction is differentially associated with cognitive distortions of the face, depending on whether it is self or other.
以往的研究表明，个体在视觉上会认为自己的眼睛尺寸比实际尺寸更大。然而，尚不清楚这种认知倾向是否会出现在对面部高度不满的人群中。因此，本研究旨在调查根据对面部的自我不满程度，个体对自己和他人眼睛的认知尺寸是否存在差异。研究参与者包括32名大学生（5名男性，27名女性；年龄：21.3±2.11岁），他们完成了面部不满量表（FDS）和一项面部识别记忆任务。该任务是选择在眼睛尺寸改变的面部照片中，自己或朋友的眼睛比实际眼睛尺寸更大还是更小。通过心理物理学函数估计与实际眼睛尺寸认知等效的眼睛尺寸。我们对FDS总分与眼睛尺寸的主观相等点（PSE）进行了相关分析。我们发现FDS与自己眼睛尺寸的PSE之间存在高度负相关。在所有他人面部的FDS与PSE之间也存在高度正相关。因此，高度的自我面部不满与对面部的认知扭曲存在差异关联，这取决于对象是自己还是他人。
