8 boys and 8 girls at each three age levels (2nd-, 4th-, and 6th grade) performed a tactile-visual recognition task, in which a tactually palpated object shape had to be matched with its analogue on a visual display. The performances of the left and right hand were compared. The results indicated that the performance of the left hand was more accurate than that of the right hand for 6th grade children while no significant difference between hands emerged in 2nd- and 4th grade children. A sex difference was found, with the right hand superior to the left hand in females but not significantly different in males. These results are discussed in relation to the development of hemisphere specialization.
三个年龄组（二年级、四年级和六年级）的8名男孩和8名女孩各进行了一项触觉视觉识别任务，即必须将通过触觉触摸到的物体形状与视觉显示屏上的类似形状进行匹配。比较了左手和右手的表现。结果表明，六年级儿童左手的表现比右手更准确，而二年级和四年级儿童双手之间没有显著差异。发现了性别差异，女性右手优于左手，而男性则没有显著差异。结合半球特化的发展对这些结果进行了讨论。
