Abstract
We replicate relations between factors of schizotypy and cognitive asy mmetry patterns assessed with recognition memory for words versus face s, and with arousal levels assessed with self-report scales. The withd rawn factor or subscales of loneliness and constricted affect were ass ociated as before with a right hemisphere, face advantage asymmetry, a s was physical anhedonia in males. Subjects with the opposite asymmetr y and those high on the active factor-eccentricity and odd speech-had high self-report activation scores. These relations better characteriz ed males who also had higher scores on the asymmetry-related factors. Females had higher scores on the third unreality factor-unusual percep tions and odd beliefs-which showed inconsistent relations with cogniti ve asymmetry. Non-right-handedness was associated with both hemisphere asymmetry patterns suggesting that the structural mechanism responsib le for non-right-handedness is associated with bidirectional hemispher ic functional imbalance. The results support the importance of pattern s of functional asymmetry in underpinning different aspects of schizot ypy.
