Prior research has shown associations between higher creativity (e.g., semantic association. verbal fluency), higher schizotypy (e.g., magical ideation), and relatively stronger right hemisphere laterality measures-when each of the three pairings has been studied individually. Our prior studs related creativity and schizotypy to signal detection theory response criterion aspects of laterality. The present study attempted to integrate findings regarding these three constructs and to replicate the signal detection theory laterality results by providing measures of all three constructs in a within subjects design. Participants ere 60 undergraduates who completed a test batters including two measures of creativity, three measures of schizotypy, a lateralized lexical decision task, and a dichotic listening, task. Results are consistent with individual differences in creativity and schizotypy being partly related to a response criterion favoring right hemisphere, possibly nonconscious, processing. Dichotic listening results revealed a strong association of better right hemisphere (left ear) localization ability and creativity. (C) 2002 Elsevier Science (USA).
