Reduced negative priming in schizotypy: Failure to replicate

Objective. The aim of the present study was to investigate the association of negative priming and schizotypal personality using a Stroop-version of the paradigm. Methods. Negative priming was determined for 160 healthy participants. Schizotypal symptoms were assessed with several schizotypal scales. Results. No significant relationship emerged between any of the schizotypal scales and negative priming. Conclusions. It is inferred that negative priming is undisturbed in schizophrenia and schizotypy when unmasked negative priming tasks are employed. Reduced negative priming in previous studies may represent an epi-phenomenon of short prime presentation times and backward masking.
