单个神经心理学病例中的认知缺陷模式是正常认知理论的常见证据来源。 特别是，工作记忆模型受益于从许多对比患者获得的数据，在某些情况下，导致工作记忆模型的修改。 在本文中，短期记忆患者和anarthric患者的数据模式与正常人的数据模式进行了比较，患者的数据模式，不同于那些模式通常发现的正常组的主题，可以被纳入一个修改版本的发音环组成部分的工作记忆模型。 然而，少数个体正常受试者也没有显示出基于正常受试者组的平均表现所报告的模式。 这会导致一些困难，在解释这些数据从这样的“异常正常”的模式，这些数据从单个患者的功能性认知defictions.The这些研究结果的神经心理学数据的解释的影响进行了讨论的工作记忆模型的背景下，但与意图，使一个一般点有关的认知功能模型的发展。 有人认为，单一的案例研究应继续提供一个有用的证据来源，提供的照顾是行使在考虑这些数据的影响模型的正常认知。
Patterns of cognitive deficit in single neuropsychological cases are common sources of evidence for theories of normal cognition. In particular, the working memory model has benefited from data obtained from a number of contrasting patients, in some cases resulting in modifications of the working memory model. In this paper, patterns of data from short-term memory patients and anarthric patients are compared with patterns of data from normal subjects.The patterns of patient data that were unlike those patterns typically found for groups of normal subjects, could be incorporated within a modified version of the articulatory loop component of the working memory model. However a small number of individual normal subjects also did not show the pattern that is reported on the basis of average performance of groups of normal subjects. This causes some difficulty in interpreting those data from such 'aberrant normal' patterns, and those data from single patients with functional cognitive deficits.The implications of these findings for the interpretation of neuropsychological data are discussed in the context of the working memory model, but with the intention of making a general point pertaining to the development of functional models of cognition. It is argued that single case studies should continue to provide a useful source of evidence, providing that care is exercised in considering the implications of such data for models of normal cognition.
