Four commissurotomy patients were tested for ability to match tachistoscopically presented stimuli with pictures in free vision, according to either structural appearance or functional/conceptual category. Patients were given ambiguous, structural, or functional instructions on any given run to trials with simultaneous double stimulus input to the two cerebral hemispheres. With ambiguous instructions, appearance and function matches were performed by the right and left hemispheres, respectively. When instructions were specific, appearance instructions tended to elicit appearance matches and right-hemisphere control. When function instructions were given, left-hemisphere control and function matches tended to be elicited. In three of the four patients, however, there was a significant number of dissociations between controlling hemisphere and strategy of matching.
对四名接受连合部切开术的患者进行了测试，以考察他们根据结构外观或功能/概念类别，将速示器呈现的刺激与自由视觉中的图片进行匹配的能力。在任何给定的测试过程中，患者会收到模糊、结构或功能方面的指示，以对同时输入到两个大脑半球的双重刺激进行试验。在模糊指示下，右半球和左半球分别进行外观和功能匹配。当指示明确时，外观指示往往会引发外观匹配和右半球控制。当给出功能指示时，往往会引发左半球控制和功能匹配。然而，在这四名患者中的三名患者中，控制半球与匹配策略之间存在大量分离现象。
