This study examined the laterality of spatial-form perception in normal adults using a cross-modal matching paradigm involving visual and tactile processing. Randomly generated eight-point and 12-point Vanderplas and Garvin (1959) patterns were used as the stimuli. In a visual-to-tactile task, a lateralized visual pattern was followed immediately by a haptic task requiring subjects to discriminate which of two simultaneously felt shapes matched the visual pattern. In a tactile-to-visual task, subjects decided which of two simultaneously felt shapes matched a lateralized visual pattern presented after haptic manipulation. There were no main effects for laterality or for sex differences. Matching accuracy was better in the visual-to-tactile task and for less complex stimuli. A visual field by feeling hand interaction showed best recognition accuracy when visual-feeling hand combinations on the same side of the body were used in the two matching tasks. These data reflect a stimulus-response compatibility explanation of spatial-form perception that is consistent with a behavioral and not a cerebral asymmetry model.
本研究采用涉及视觉和触觉处理的跨模态匹配范式，考察了正常成年人空间形式感知的偏向性。随机生成的八点和十二点范德普拉斯和加文（1959）图案用作刺激物。在视觉到触觉任务中，一个偏向一侧的视觉图案之后紧接着是一个触觉任务，要求受试者辨别同时触摸到的两个形状中哪一个与视觉图案匹配。在触觉到视觉任务中，受试者要判断同时触摸到的两个形状中哪一个与触觉操作后呈现的偏向一侧的视觉图案匹配。在偏向性或性别差异方面没有主效应。在视觉到触觉任务以及对于不太复杂的刺激物，匹配准确率更高。当在两个匹配任务中使用身体同一侧的视觉-触摸手组合时，视野与触摸手的交互显示出最佳识别准确率。这些数据反映了空间形式感知的刺激-反应兼容性解释，这与行为模型而非大脑不对称模型一致。
