THE REPRESENTATION OF SEMANTIC CATEGORIES

正在开发一种语义范畴表示模型来解释 对于各种各样的归类现象。在以前的工作中，我们 论证了主要由内在特征表示的类别 (即，孤立对象的特征为真)和所表示的那些 主要通过外在特征(即实体之间的关系)不同 在结构上。这一方法已被扩展到解释语境效应 在分类中，主体之间的不一致 范畴化判断和表象中的等级 语义关系。最近，我们将项目范围扩大到 研究基于样本和基于抽象的含义 人们对必然性判断的范畴表征模型 范畴意义上的特征。

A model of semantic category representation is being developed to account for a variety of categorization phenomena. In previous work, we demonstrated that categories represented primarily by intrinsic features (i.e., features true of an object in isolation) and those represented primarily by extrinsic features (i.e., relations among entities) differ in structure. This approach has been extended to explain context effects in categorization, inter-subject disagreement among subjects in categorization judgments, and gradedness in the representation of semantic relations. Recently, we have broadened the project to investigate the implications of exemplar-based and abstraction-based models of category representation for people's judgments of the necessity of features in category meaning.
