心理旋转任务的性别差异，有利于男性，已注意到在行为研究和功能成像研究。在本研究中，10名女性和10名男性志愿者接受了常规区组设计的功能磁共振成像。在扫描仪内执行心理旋转任务后，检测到激活区域。与以前的研究相比，排除了性别之间的性能差异或高错误率等混杂因素。男性表现出更强的顶叶激活，而女性则表现出更强的右额叶激活。我们的研究结果表明，在心理旋转任务中涉及的神经心理过程中存在性别特异性差异。(C)2003爱思唯尔科学爱尔兰有限公司保留所有权利。
Sex differences in mental rotation tasks, favoring men, have been noted in behavioral studies and functional imaging studies. In the present study ten female and ten male volunteers underwent functional magnetic resonance imaging in a conventional block design. Regions of activation were detected after performance of a mental rotation task inside the scanner. In contrast to previous studies, confounding factors such as performance differences between genders or high error rates were excluded. Men showed significantly stronger parietal activation, while women showed significantly greater right frontal activation. Our results point to gender specific differences in the neuropsychological processes involved in mental rotation tasks. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.
