The theory of callosal failure in schizophrenia is examined using the test for left-hand anomia. It is argued that if the corpus callosum is affected in schizophrenia with consequent difficulty of transmission between the two sides of the brain, a greater number of left-hand errors should be found in producing the names of objects held by that hand because the speech area of the left hemisphere is no longer available for the description of the perceptions of the left hand. The findings support this view and they confirm the communication failures of the brain related to callosal disturbance.
运用左手命名障碍测试对精神分裂症中胼胝体功能障碍理论进行了研究。有人认为，如果胼胝体在精神分裂症中受到影响，导致大脑两侧之间的信息传递出现困难，那么在说出左手所持物体的名称时，左手出现错误的次数应该更多，因为左半球的语言区域无法再用于描述左手的感知。研究结果支持了这一观点，并证实了与胼胝体紊乱相关的大脑信息交流障碍。
