患者MS，接受右枕叶切除术治疗顽固性癫痫的患者，对单词的回忆和识别记忆完整，但在单词识别和视觉词干完成任务中的重复启动受损。这种对遗忘的镜像分离表明，外显再认和视知觉重复启动是由不同的神经系统介导的。然而，在之前的研究中，M.S.识别记忆只在那些需要他完整的语言知识的任务中进行测试。本研究探讨了MS。非言语知觉信息的再认记忆，即词语呈现的形式和字体以及线条图案。M.S.再认记忆是完整的，进一步证明知觉外显和内隐记忆过程是由功能和神经独立的记忆系统所支配的。
Patient M.S., who underwent right-occipital lobe resection to treat intractable epilepsy, has intact recall and recognition memory for words, but impaired repetition priming in word identification and visual stem-completion tasks. This mirror dissociation to amnesia suggests that explicit recognition and visuoperceptual repetition priming are mediated by distinct neural systems. In prior studies, however, M.S.' recognition memory was tested only with tasks that drew upon his intact verbal knowledge. The present study examined M.S.' recognition memory for nonverbal perceptual information, namely, the modality and font of word presentation and line patterns. M.S.' recognition memory was intact, providing further evidence that perceptual explicit and implicit memory processes are subserved by functionally and neurally independent memory systems.
