Neuropsychological differentiation of adaptive creativity and schizotypal cognition

Both creativity and schizophrenia-spectrum disorders have been associated with activation of remote semantic concepts, but this activation results in innovative output in one case and communication disturbances in the other. The present study examined the relationship between monitoring semantic information (which relies on executive brain function), creativity, and characteristics of schizotypy in an undergraduate population. Results indicate that executive function differentiates the use of semantic information in creativity and schizotypy. Specification of the balance between executive monitoring and activation of semantic information is important for determining how communication disturbances manifest, and for the measurement of creativity and schizotypy in the general population.

► Unusual use of semantic information is common in schizotypy and creativity.
► We examined activation and monitoring of semantic information.
► Activation and monitoring of semantic concepts are differentiated by executive function.
► Executive function measures are useful for differentiating creativity and schizotypy.
