In a simple reaction time task, key-pressing responses to unpatterned light stimuli presented in the right and left visual fields were faster for the hand ipsilateral to the visual stimulus than for the hand contralateral to the stimulus. The superiority of the ipsilateral reactions was seen also when responses were made with the hands crossed, so that such a superiority cannot be attributed to spatial compatibility between the side of the stimulus and the position of the response device. Similar results were obtained in a reaction time task of the Donders's c-type. It is argued that these laterality effects in visuomotor reaction time tasks are best explained by the anatomical relationships between the visual fields, the cerebral hemispheres, and the hands. The possible interaction between these effects and the effects of spatial compatibility between side of stimulus and side of response device are discussed in relation to reaction time tasks of the Donder's b-type.
在一个简单反应时任务中，对于呈现于右视野和左视野的无模式光刺激，对视觉刺激同侧的手做出的按键反应比对刺激对侧的手更快。当双手交叉做出反应时，同侧反应的优势同样可见，所以这种优势不能归因于刺激侧与反应装置位置之间的空间兼容性。在唐德斯c型反应时任务中也得到了类似结果。有人认为，视觉运动反应时任务中的这些偏侧性效应最好用视野、大脑半球和手之间的解剖学关系来解释。结合唐德斯b型反应时任务，讨论了这些效应与刺激侧和反应装置侧之间空间兼容性效应可能存在的相互作用。
