Abstract 

Consistent with the possibility that the right hemisphere is responsible for processing information about the self, subjects responded faster with their left hand to adjectives that were self-descriptive. However, those who scored high on the Schizotypal Personality Questionnaire (SPQ) did not show a left-hand advantage. These data add to a growing body of evidence that implicates the right hemisphere in processing information about the self and supports the hypothesis that self-processing may be impaired in schizophrenic-like populations.
