Abstract
Since Eleanor Rosch’s groundbreaking work in the 1970s, conceptual knowledge has become a subject of extensive research in cognitive psychology. This chapter provides an overview of the current state of the art. Research has focused on conceptual knowledge about concrete physical things. The main research questions concern the structure and content of conceptual knowledge and its functions, in particular categorization. Most research is based on the view that conceptual knowledge comprises a set of relatively fixed packets of information, or concepts, which are assumed to correspond to lexical meanings. This view of the relationship between conceptual and lexical-semantic knowledge is discussed towards the end of the chapter.
