Atypical lateralization in emotional prosody in men with schizotypy
Najt, P.; Bayer, U.; Hausmann, M.
Abstract
Individuals high in schizotypy have been shown to reveal reduced lateralisation in verbal processing which may be influenced by an impaired left hemisphere performance. However, little is known about schizotypy and right hemisphere functions such as emotional perception. The present study focuses on atypical lateralisation in language and emotional prosody in Impulsive Non-conformity (IMP), a specific aspect of schizotypy. A total of 41 participants (20 females) performed a dichotic listening linguistic and emotional prosody task, which typically shows a right ear advantage (REA) and left ear advantage (LEA), respectively. A median split based on the IMP scale included in the Oxford-Liverpool Inventory of Feelings and Experiences was used to divide the sample into high and low scorers. The results revealed a selective reduction of the LEA in the prosody task in high-IMP males. Females high and low in IMP revealed typical lateralisation in both tasks. The results indicate that high-IMP males are especially prone to atypical lateralisation in emotional prosody, which parallels those findings in male patients with schizophrenia. The results suggest similarities in sex-specific atypical brain organisation between schizotypy and schizophrenia.
