A left-hand advantage for self-description: the impact of schizotypal personality traits.
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.

Contagious yawning: the role of self-awareness and mental state attribution.
Contagious yawning is a common, but poorly understood phenomenon. We hypothesized that contagious yawning is part of a more general phenomenon known as mental state attribution (i.e. the ability to inferentially model the mental states of others). To test this hypothesis we compared susceptibility to contagiously yawn with performance on a self-face recognition task, several theory of mind stories, and on a measure of schizotypal personality traits. Consistent with the hypothesis, susceptibility to contagiously yawn was positively related to performance on self-face recognition and faux pas theory of mind stories, and negatively related to schizotypal personality traits. These data suggest that contagious yawning may be associated with empathic aspects of mental state attribution and are negatively affected by increases in schizotypal personality traits much like other self-processing related tasks.
