Witelson (1976) found that boys but not girls showed right-hemisphere specialization for tactile-spatial processing as early as 6 yr. of age. In the present study, Witelson's task was administered to 46 normal 4- and 5-yr.-old girls and boys. Both sexes showed right-hemisphere specialization. There were no sex differences either in specialization or in over-all performance.
维特尔森（1976年）发现，早在6岁时，男孩而非女孩在触觉空间处理方面就表现出右半球优势。在本研究中，对46名4岁和5岁的正常女孩和男孩进行了维特尔森的任务测试。两性均表现出右半球优势。在优势方面或总体表现上均无性别差异。
