A configural theory of human amnesia is proposed. The theory predicts that amnesic patients will exhibit selective deficits on tasks that normal subjects perform by learning new configurations of stimulus elements. This prediction is supported by results for four amnesic patients who learned a nonconfigural control task but failed to learn the configural transverse patterning task even after extensive practice. Matched normal subjects easily learned both tasks. The theory provides unique and viable accounts of the central results in the human amnesia literature. Relations between the configural approach and other theories are discussed.
提出了一种关于人类失忆症的构型理论。该理论预测，失忆症患者在正常受试者通过学习刺激元素的新构型来完成的任务上会表现出选择性缺陷。四名失忆症患者的结果支持了这一预测，他们学会了一项非构型控制任务，但即使经过大量练习，仍未能学会构型横向模式任务。匹配的正常受试者很容易学会这两项任务。该理论为人类失忆症文献中的核心结果提供了独特且可行的解释。讨论了构型方法与其他理论之间的关系。
