Psychologists: Are They Logically Fuzzy?

Fuzzy logic as a basis for modeling concepts was rejected by psychologists because of an influential paper published by Osherson and Smith in 1981. While Osherson and Smith were important and influential psychologists, they were not logicians. A critical analysis of their work reveals a series of tired arguments. If, in fact, fuzzy logic can be used to model psychological concepts, can fuzzy logic offer any insight into areas central to the psychology of concepts? In addition, can psychology offer any insight into the methodology of fuzzy logic? Can data from experiments in learning concepts point to more robust methods in fuzzy logic systems?
