Face recognition failures in schizotypy.
BACKGROUND
Studies suggest an important role of disturbances of self in schizophrenia and in schizotypy. Based on findings from a previous study (Brédart & Young, 2004), we developed a questionnaire assessing self-face recognition failures in everyday life (Self-Face Recognition Questionnaire; SFRQ) to investigate the relations between dimensions of schizotypy (cognitive-perceptual, interpersonal, disorganised) and self-face recognition disturbances.


METHODS
A sample of nonclinical participants (n = 170) completed the SFRQ and the Schizotypal Personality Questionnaire.


RESULTS
Factor analysis of SFRQ items revealed a clear three-factor structure consisting of: (1) self-face recognition difficulties, (2) unusual perception of own or other faces, and (3) other-face recognition difficulties. Correlational analyses between schizotypy dimensions and the SFRQ revealed that only the cognitive-perceptual and disorganised schizotypy dimensions correlated significantly with the SFRQ. By contrast, the interpersonal schizotypy dimension was not associated with the SFRQ.


CONCLUSIONS
Findings provide further support that positive (cognitive-perceptual) and negative (interpersonal) schizotypy represent discrete neurobehavioural dimensions. The theoretical implications of these findings are discussed.
