On the Robustness of Prime Response Retrieval Processes: Evidence from Auditory Negative Priming without Probe Interference

Abstract

Visual negative priming has been shown to depend on the presence of probe distractors, a finding that has been traditionally seen to support the episodic retrieval model of negative priming; however, facilitated prime-to-probe contingency learning might also underlie this effect. In four sound identification experiments, the role of probe distractor interference in auditory negative priming was investigated. In each experiment, a group of participants was exposed to probe distractor interference while another group ran the task in the absence of probe distractors. Experiments 1A, 1B, and 1C varied in the extent to which fast versus accurate responding was required. Between Experiments 1 and 2, the spatial cueing of the to-be-attended ear was varied. Whereas participants switched ears from prime to probe in Experiment 1, they kept a stable attentional focus throughout Experiment 2. For trials with probe distractors, a negative priming effect was present in all experiments. For trials without probe distractors, the only ubiquitous after-effect of ignoring a prime distractor was an increase of prime response errors in ignored repetition compared to control trials, indicating that prime response retrieval processes took place. Whether negative priming beyond this error increase was found depended on the stability of the attentional focus. The findings suggest that several mechanisms underlie auditory negative priming with the only robust one being prime response retrieval.
