Geneplore model

In 1992, Finke et al. proposed the "Geneplore" model, in which creativity takes place in two phases: a generative phase, where an individual constructs mental representations called "preinventive" structures, and an exploratory phase where those structures are used to come up with creative ideas. Some evidence shows that when people use their imagination to develop new ideas, those ideas are structured in predictable ways by the properties of existing categories and concepts. Weisberg argued, by contrast, that creativity involves ordinary cognitive processes yielding extraordinary results.
