一个基本的问题是人们是否有一个可用的类别学习系统，或许多。大多数多元体系的倡导者假定一个显性体系和一个隐性体系。虽然对显性制度的性质有很多共识，但对隐性制度的性质却不太一致。在这篇文章中，我们回顾了由Ashby等人（1998）提出的类别学习的双系统理论，称为言语系统和内隐系统之间的竞争（COVIS）。外显系统支配着可言语化的、基于规则的类别结构的学习，并由前扣带回、前额叶皮质（PFC）和尾状核头部等额叶脑区介导。内隐系统，它使用程序学习，占主导地位的非言语化，信息整合类别结构的学习，并介导的尾状核的尾巴和多巴胺介导的奖励信号。我们回顾了9项研究，这些研究测试了COVIS的6个先验预测，每个预测都得到了数据的支持。(C)2004 Elsevier B.V.保留所有权利。
A fundamental question is whether people have available one category leaming system, or many. Most multiple systems advocates postulate one explicit and one implicit system. Although there is much agreement about the nature of the explicit system, there is less agreement about the nature of the implicit system. In this article, we review a dual systems theory of category learning called competition between verbal and implicit systems (COVIS) developed by Ashby et al. (1998). The explicit system dominates the learning of verbalizable, rule-based category structures and is mediated by frontal brain areas such as the anterior cingulate, prefrontal cortex (PFC), and head of the caudate nucleus. The implicit system, which uses procedural learning, dominates the learning of non-verbalizable, information-integration category structures, and is mediated by the tail of the caudate nucleus and a dopamine-mediated reward signal. We review nine studies that test six a priori predictions from COVIS, each of which is supported by the data. (C) 2004 Elsevier B.V. All rights reserved.
