Creativity and Cognitive Control: Explorations of Generation and Evaluation Skills

Two experiments are reported in which relationships between cognitive control and generative as well as evaluative aspects of creativity were studied. Cognitive control was assessed through the interference effects of the Navon and Stroop tasks. Generative and evaluative aspects of creativity were studied with a procedure, called Generation and Evaluation (GenEva). Each participant first generated a number of solutions to a set of divergent problems, and then he or she evaluated solutions provided by another participant, chosen at random. The data suggest that participants scoring high on Urban and Jellen's Test for Creative Thinking-Drawing Production showed better indexes of cognitive control than participants with lower scores. A similar relationship has been found concerning the originality of participants' productions (GenEva procedure) but not their fluency and flexibility. These findings are interpreted in terms of basic cognitive processes, which are probably responsible for idea production. It also appeared that cognitive control allowed more accurate evaluation of other people's ideas, but only in the case of participants with global cognitive style of information processing.
