Changes of simple visual reaction time were analyzed in two groups of unilateral brain damaged patients in order to evaluate to what extent intrahemispheric localization of lesions affects performance. Possible interactions with size were avoided by selecting a localization criterion, i.e. the median section of lesion, uncorrelated with size of damage. By preliminarly establishing that the distribution of lesions in our hemispheric groups did not differ, we were enabled to confirm that intrahemispheric localization of damage has a different bearing on performance depending on side of lesion. In the right hemisphere group slower performances were generally associated with frontal damage whereas in the left hemisphere group localization did not influence the performance. The use of independent indexes for size and locus of lesion proved the existence of an interaction between these parameters in the right hemisphere group.
为了评估病变的半球内定位在多大程度上影响表现，对两组单侧脑损伤患者的简单视觉反应时变化进行了分析。通过选择一个与损伤大小无关的定位标准，即病变的中间截面，避免了与大小可能的相互作用。通过初步确定我们半球组中病变的分布没有差异，我们得以证实，根据病变侧的不同，损伤的半球内定位对表现有不同的影响。在右半球组中，表现较慢通常与额叶损伤有关，而在左半球组中，定位并不影响表现。对病变大小和位置使用独立指标证明了在右半球组中这些参数之间存在相互作用。
