Reduced negative priming in schizotypy: failure to replicate
Steffen Moritz1, Burghard Andresen1
1University of Hamburg, Germany.
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.
