Hemisphere and gender differences in mental rotation for tachistoscopically presented stimuli were assessed in 40 right-handed university students. Twenty male and 20 female subjects each were individually administered (via computer) a mental rotation task which included 10 stimulus presentations at each of eight angular disorientations (0 degrees, 45 degrees, 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, and 315 degrees) in each visual half-field (VHF) for a total of 160 trials. Analyses of variance performed on reaction time and accuracy data revealed only a main effect for orientation. A typical mental rotation function for both the left VHF and the right VHF for both genders resulted; however, no gender x visual field interaction was found. Lack of hemisphere and gender differences provide further evidence questioning the interpretation of right-hemisphere male superiority for spatial tasks. Investigation into factors such as task complexity, stimulus familiarity, and task demands may lend further insight into hemisphere and gender differences in mental rotation.
对40名右利手大学生进行了速示呈现刺激的心理旋转半球和性别差异评估。20名男性和20名女性受试者分别（通过计算机）接受了一项心理旋转任务，该任务在每个视觉半视野（VHF）中的八个角度方向（0度、45度、90度、135度、180度、225度、270度和315度）各有10次刺激呈现，总共160次试验。对反应时间和准确性数据进行的方差分析仅显示出方向的主效应。得出了男女在左VHF和右VHF上典型的心理旋转函数；然而，未发现性别×视野交互作用。缺乏半球和性别差异为质疑空间任务中右半球男性优势的解释提供了进一步的证据。对任务复杂性、刺激熟悉度和任务要求等因素的研究可能会进一步深入了解心理旋转中的半球和性别差异。
