This study was to provide basic norms of Korean natural categories. In the first part, an exemplar production frequency norm was constructed. In the second part, typicality norm was established following the procedures employed by Rosch & Mervis(1975). In the third part, defining features of each category were listed, and estimates(Ws) reflecting dependency of each category on external features were also calculated. This study provides not only basic materials to psychology and related areas but also bases for further study of the internal structure of Korean natural categories.
