Sex differences in human brain lateralization are documented by studies on normal subjects, patients with the unilateral brain damage, and individuals with atypical level of hormones. However, there is no agreement as to the specific role of gender in the development of hemispheric asymmetry. This experiment was designed to examine whether gender identity plays an important role in the formation of brain lateralization, as some recent data seem to suggest. A group of subjects showing gender dysphoria (transsexuals) and two groups of control male and female subjects were presented with verbal and visual-spatial tasks. Results show that neither biological sex nor gender identity are sufficient factors to determine the pattern of hemispheric asymmetry.
对正常受试者、单侧脑损伤患者以及激素水平异常的个体进行的研究记录了人类大脑偏侧化中的性别差异。然而，关于性别在半球不对称发展中的具体作用尚无定论。本实验旨在检验性别认同是否如最近一些数据所表明的那样，在大脑偏侧化的形成中发挥重要作用。一组表现出性别焦虑的受试者（变性者）以及两组分别作为对照的男性和女性受试者参与了语言和视觉空间任务。结果表明，生理性别和性别认同都不是决定半球不对称模式的充分因素。
