The purpose of this report was to examine facial asymmetry during the expression of positive and negative emotions. In addition, methodological factors in the study of facial asymmetry were considered. Subjects were 16 neurologically-healthy right-handed adult males, videotaped while posing eight facial expressions (positive and negative) under two conditions (verbal command and visual imitation). Separate asymmetry ratings of the two sides of the face were made by judges viewing normal or mirror-reversed versions of the videotape. There were no effects of valence, condition, or videotape orientation on the asymmetry ratings, and, in general, expressions were produced significantly more intensely on the left than the right side of the face. This finding is consistent with the hypothesis that the right cerebral hemisphere is dominant for the expression of facial emotion of both valences.
本报告的目的是研究在表达积极和消极情绪时的面部不对称情况。此外，还考虑了面部不对称研究中的方法学因素。研究对象为16名神经功能正常的右利手成年男性，他们在两种条件下（言语指令和视觉模仿）做出8种面部表情（积极和消极）时被录像。评判者通过观看录像带的正常版本或镜像反转版本对面部两侧进行单独的不对称评分。效价、条件或录像带方向对面部不对称评分均无影响，并且一般来说，面部左侧产生的表情比右侧更强烈。这一发现与右脑半球在两种效价的面部情绪表达中占主导地位的假设一致。
