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.
