This article discusses three important models of concept combination—Smith and colleagues' Selective Modification model, Hampton's Composite Prototype model, and Costello and Keane's C3 model. Smith and colleagues' famous model of concept combination combines a model for producing complex concepts out of simple concepts with a prototype model of concept representation and a metric for computing the typicality of objects with respect to those concepts. The model of concept combination proposed by Smith and colleagues applies only to modifier–head complex concepts. Hampton's model of concept combination includes, along with a qualitative description of the process resulting in complex concepts, a model of concepts, a model of categorization, and a model of typicality judgement. For Hampton, concept combination consists in the inheritance of typical properties from the combined concepts by the complex concept.
