Abstract

Concepts have been a focus of research in developmental psychology for more than 50 years, although the target article does not refer to these uses of the concept of “concept.” I summarize some of the developmental research that is relevant to the issues raised. Cognitive content, concepts as internal products of memory, and the relation of internal concepts to language learning are pointed out important problems in considering the usefulness of the construct in psychology. 2012 APA, all rights reserved)
