TY - JOUR AU - Hampton, James A. PY - 1981 DA - 1981/03/01 TI - An investigation of the nature of abstract concepts JO - Memory & Cognition SP - 149 EP - 156 VL - 9 IS - 2 AB - Eight abstract concepts were submitted to a procedure designed to test the logical nature of their definition. The hypothesis that they would show a polymorphous prototype structure similar to that found for concrete categories (Hampton, 1979; Rosch & Mervis, 1975) was confirmed for five of the concepts. Reasons for the lack of fit of the prototype model to the remaining concepts and implications for the generality of existing theories of semantic memory are discussed.
