This study examined both perceiver and poser asymmetries in processing facial emotion. Posers were left brain-damaged (LBD), right brain-damaged (RBD), and normal control (NC) right-handed males videotaped while expressing happiness and anger. Perceivers rated the facial expressions for asymmetry in original and reversed orientations. Overall, expressions viewed in the reversed orientation were rated as more left-sided than in the original orientation. In the reversed orientation, the more extensive left hemiface of the NCs and LBDs fell in the perceiver's left hemispace. This finding is consistent with previous research demonstrating a left hemispace bias for free-field viewing of emotional faces. Expressions were produced significantly more intensely on the left than the right hemiface by NCs and LBDs; expressions of RBDs were not significantly lateralized.
本研究考察了在处理面部情绪时感知者和表达者的不对称性。表达者为左脑损伤（LBD）、右脑损伤（RBD）和正常对照（NC）的右利手男性，他们在表达快乐和愤怒时被录像。感知者对原始和反转方向的面部表情不对称性进行评分。总体而言，与原始方向相比，反转方向的表情被评为更偏向左侧。在反转方向上，NC组和LBD组更广泛的左半脸落在感知者的左半空间。这一发现与先前的研究一致，该研究表明在自由视野观看情绪面孔时存在左半空间偏向。NC组和LBD组在左半脸产生的表情明显比右半脸更强烈；RBD组的表情没有明显的偏侧化。
