ABSTRACT
Many theories of problem solving have assumed a role for implicit cognitive processes. For instance, implicit processes are sometimes used to generate hypotheses that are explicitly tested until a problem is solved (heuristic-analytic theory). Also, Wallas' stage decomposition of creative problem solving included an implicit stage called 'incubation'. As a result, implicit processes are thought to be responsible for many correct solutions when solving insight problems. In this presentation, we propose a new unifying theory of creative problem solving that benefits from the integration of explicit and implicit processing. Furthermore, we implement the new theory in the framework of the CLARION cognitive architecture. The resulting model is used to simulate data showing the effect of incubation in a lexical decision task and a free recall task. In addition, data related to insight and overshadowing in creative problem solving are also captured by the new model.
