Abstract

Three groups of normal female subjects (7 and 8 years of age, 13 and 14 years of age, and young adults) were tested on a choice reaction time task using a tachistoscopic presentation of single letters to either hemisphere. The two older groups of subjects were found to exhibit a significant right visual field (left hemisphere) superiority in reaction time to letters, but the 7 and 8 year old children did not show a hemisphere asymmetry. These reaction time results for the two older groups are consistent with Rizzolatti et al.'s (1971) finding of a right visual field superiority in reaction time to letters in male adults. The analyses of error rates for visual field differences were not significant for the children or the adolescents. In this study, in contrast to Rizzolatti et al.'s result with male adults, the female adults produced a significant visual field difference in error rate.

摘要

三组正常女性受试者（7至8岁、13至14岁以及年轻成年人）参与了一项选择反应时间任务测试，该测试通过速示器向任一脑半球呈现单个字母。结果发现，年龄稍大的两组受试者在对字母的反应时间上表现出显著的右视野（左脑半球）优势，但7至8岁的儿童未表现出半球不对称性。年龄稍大的两组受试者的这些反应时间结果与里佐拉蒂等人（1971年）在成年男性中发现的对字母的反应时间存在右视野优势的结果一致。对儿童和青少年而言，视野差异的错误率分析并无显著差异。在本研究中，与里佐拉蒂等人对成年男性的研究结果不同，成年女性在错误率上产生了显著的视野差异。
