Differences between dyslexics and controls in the unimanual and bimanual conditions of the peg placement section of the Purdue Pegboard Test were examined. Twenty-three disabled and twenty-three normal readers were studied. The groups were carefully screened on a neuropsychological battery. The disabled readers were comprised of a relatively homogeneous language-disordered subgroup exhibiting deficits in naming. Significant Group X Condition interactions were obtained for both raw and percentile scores and indicated that disabled readers performed worse than controls in the unimanual compared to bimanual conditions. The dyslexics performed particularly poorly compared with controls on the left hand condition. The implications of these data for hypotheses which argue for left hemisphere dysfunction, as well as those which posit interhemispheric transfer deficits in reading disabled children, are discussed.
研究了诵读困难者与对照组在普渡钉板测试中钉子放置部分单手和双手条件下的差异。对23名阅读障碍者和23名正常阅读者进行了研究。通过一套神经心理学测试对两组进行了仔细筛选。阅读障碍者包括一个相对同质的语言障碍亚组，表现出命名缺陷。对于原始分数和百分位数分数，均获得了显著的组×条件交互作用，表明在单手条件下与双手条件相比，阅读障碍者的表现比对照组差。在左手条件下，诵读困难者与对照组相比表现尤其差。讨论了这些数据对主张左半球功能障碍的假设以及那些假定阅读障碍儿童存在半球间传递缺陷的假设的意义。
