In order to test the hypothesis of right hemisphere changes with age, this study examined lateralization for facial emotion in young, middle-aged, and older women (N = 90). For expression, subjects were photographed while posing positive and negative emotions. Composite photographs were created and rated for intensity. For perception, subjects were required to make intensity judgements about emotional chimeric faces. Overall, subjects demonstrated significant left-sided facial asymmetry for expression and significant left hemispace biases for perception. The findings for facial expression were not influenced by emotional valence or resting face asymmetries. There were no changes in lateralization as a function of age for either expression or perception. Taken together, these findings lend support to the notion that the right hemisphere mediates emotional processing across the adult life span.
为了验证随着年龄增长右半球会发生变化这一假设，本研究对年轻、中年和老年女性（N = 90）的面部情绪偏侧化进行了考察。在表情方面，让受试者摆出积极和消极情绪的姿势并拍照。制作合成照片并对其强度进行评分。在感知方面，要求受试者对情绪嵌合面孔的强度做出判断。总体而言，受试者在表情上表现出显著的左侧面部不对称，在感知上表现出显著的左半空间偏向。面部表情的研究结果不受情绪效价或静息面部不对称的影响。表情或感知的偏侧化均未随年龄变化。综上所述，这些研究结果支持了右半球在成年期介导情绪加工的观点。
