The preservation of visuospatial ability relative to verbal ability following right middle cerebral artery stroke was assessed in 19 left- and 19 right-handed male patients who were group-matched on the basis of age, education, and time elapsed since stroke. Analysis of covariance (covarying education) indicated that the left- and right-handed groups were significantly different with regard to the discrepancy between Verbal IQ and Performance IQ, with the left-handed patients showing a smaller difference than the right-handers. These results provide further evidence that sinistrality may be associated with less hemispheric specialization.
在19名左利手和19名右利手男性患者中评估了右大脑中动脉卒中后视觉空间能力相对于语言能力的保留情况，这些患者在年龄、教育程度和卒中后经过的时间方面进行了组间匹配。协方差分析（将教育程度作为协变量）表明，左利手组和右利手组在言语智商和操作智商之间的差异方面存在显著差异，左利手患者的差异比右利手患者小。这些结果提供了进一步的证据，表明左利手可能与较少的半球特化有关。
