Evidence of vocal and manual event files in auditory negative priming

Negative priming with auditory as well as with visual stimuli has been shown to involve the retrieval of prime response information as evidenced by an increase of prime response errors to the probes of ignored repetition trials compared to control trials. We investigated whether prime response retrieval processes were also present for response modalities other than manual responding. In an auditory four alternative forced choice task participants either vocally or manually identified a target sound while ignoring a distractor sound. Negative priming was of equal size in both response modalities. What is more, for both response modalities, there was evidence of increased prime response errors in ignored repetition trials compared to control trials. The findings suggest that retrieval of event files of the prime episode including prime response information is a general mechanism underlying the negative priming phenomenon irrespective of stimulus or response modality.
