The purpose of this study was to examine the relationship between sex role and spatial ability using both performance and electrocortical (EEG) measures. Two hundred and fifty four subjects were given the Differential Aptitudes Space Relations Test and a short form of the Personal Attributes Questionnaire (PAQ) which gives an indication of sex role. From this initial group, 40 males and females were chosen based on sex role scores. These subjects were asked to solve additional visuo-spatial problems. Bilateral EEG measures were taken from the frontal and parietal areas. The results indicate that frontal EEG measures are related to the sex role orientation of the subjects whereas parietal EEG measures are associated with performance on the visuo-spatial task for males but not females. These results suggest that frontal and parietal EEG measures reflect different processes. Counter to the traditional hypothesis, performance on the visuo-spatial task was negatively related to masculine sex-role orientation suggesting that factors which influence spatial processing go beyond biological sex.
本研究的目的是使用行为表现和皮层电活动（脑电图，EEG）测量方法来检验性别角色与空间能力之间的关系。254名受试者接受了鉴别能力空间关系测试以及一份能表明性别角色的简化版个人属性问卷（PAQ）。从这个初始群体中，根据性别角色得分挑选出40名男性和女性。这些受试者被要求解决额外的视觉空间问题。从额叶和顶叶区域进行双侧脑电图测量。结果表明，额叶脑电图测量结果与受试者的性别角色取向有关，而顶叶脑电图测量结果与男性在视觉空间任务中的表现相关，与女性无关。这些结果表明，额叶和顶叶脑电图测量反映了不同的过程。与传统假设相反，视觉空间任务的表现与男性化性别角色取向呈负相关，这表明影响空间处理的因素超出了生理性别。
