摘　　要：目的:探讨心理旋转任务中的性别差异是否受工作记忆的负荷的影响。方法:采用先后呈现提示刺激和目标刺激的范式,任务分为三种:1.无效提示的数字旋转;2.有效提示的数字旋转;3.有效提示的PMA图形旋转。结果:重复测量的方差分析表明:对无效提示的数字旋转任务,男性和女性之间的反应时和正确率都无差异;对有效提示的数字旋转任务,男性和女性之间的正确率无差异,而反应时的差异边缘显著;对有效提示的PMA图形旋转任务,男性和女性之间的正确率无差异,而反应时有显著差异。结论:工作记忆的负荷可能会影响心理旋转任务中的性别差异。Objective： To explore whether the sex differences in mental rotation were affected by working memory load. Methods： Successive presentation paradigms were used. There were three tasks： 1. number rotation with useless cue; 2. number rotation with cue; 3. PMA figure rotation with cue. Results： Analysis of variance of repeated measures indicated that： for the task of number rotation with useless cue, neither accuracy nor response time had significant differences between sexes; for the task of number rotation with cue, the accuracy had no significant difference between sexes while the response time had marginal significant difference between sexes; for the task of PMA figure rotation, the accuracy had no significant difference between sexes while the response time had significant difference between sexes, Conclusion： The working memory load could affect sex differences in mental rotation.
