In a sample of 53 right-handed, young adult males, asymmetry was examined in the size of 11 facial regions, in total area, and in emotional expression of the face at rest. In the complete sample no evidence was obtained of consistent asymmetry in size of facial regions, in facial area, or in emotional expression. There was, however, an interaction between family history of sinistrality and sighting dominance in facial asymmetry for the pleasantness/unpleasantness of facial expression. The findings suggest that previously established asymmetries in phasic emotional displays are not an outcome of expressive or morphological asymmetries of the face at rest.
在一个由53名右利手的年轻成年男性组成的样本中，研究人员检查了11个面部区域的大小、总面积以及静息时面部的情绪表达的不对称性。在整个样本中，未发现面部区域大小、面部面积或情绪表达存在一致的不对称性证据。然而，对于面部表情的愉悦/不悦程度，利手家族史与注视优势之间在面部不对称性方面存在交互作用。研究结果表明，先前确定的阶段性情绪表现中的不对称性并非静息时面部表达性或形态学不对称的结果。
