Hemisphere specialization for mental rotation was investigated utilizing Shepard's (1971) paradigm. In each of two experiments, the procedure involved presenting pairs of novel non-verbal stimuli at various angles of disparity. Subjects were instructed to construct a mental image of one stimulus, rotate this image, and judge whether or not the image was a congruent match with its mate. Both response time and accuracy were measured. In Experiment 1, the testing of right-handed normals revealed a significant left visual field advantage for accuracy (p less than .0001) and response time (p less than .05). In Experiment 2, a comparison of right parietal lesioned patients with both left parietal lesioned patients and matched normal controls likewise revealed significant right lesion effects for accuracy (p greater than .0001) and response time (p greater than .01). Right hemisphere specialization for mental rotation was documented for both normals and brain damaged subjects.
利用谢泼德（1971年）的范式对心理旋转的半球特化进行了研究。在两个实验中的每一个实验里，程序都包括以不同的视差角度呈现一对新颖的非语言刺激。受试者被要求构建一个刺激的心理图像，旋转这个图像，并判断该图像与其配对物是否完全匹配。测量了反应时间和准确性。在实验1中，对右利手正常人的测试显示，在准确性方面有显著的左视野优势（p小于0.0001），在反应时间方面也有显著优势（p小于0.05）。在实验2中，将右顶叶损伤患者与左顶叶损伤患者及匹配的正常对照组进行比较，同样显示在准确性方面有显著的右损伤效应（p大于0.0001），在反应时间方面也有显著效应（p大于0.01）。记录了正常人和脑损伤受试者在心理旋转方面的右半球特化情况。
