How a person’s social categories are related to that person’s concepts: Many theories of categorization in psychology (see Cohen &amp; Lefebvre 2005) treat a person’s concepts interchangeably with the categories that person imposes on the world. The so-called internalist versions of these theories take a person’s concepts to ontologically depend on states of the person’s brain alone. These theories take a person’s social categories to be the same as her concepts, which are internal mental states. Other mentalistic theories of social categories do not fit this mold. It may be that a person’s social categories are generated by that person’s mental states, without the categories having to be conceptualized.
