On distractor-repetition benefits in the negative-priming paradigm

The present study investigates the effects of distractor repetitions between prime and probe displays on behaviour in the negative-priming (NP) paradigm. Investigating this condition is theoretically significant because inhibition-based accounts and episodic retrieval accounts of NP on one side and the temporal-discrimination theory on the other side make opposite predictions with regard to the effects of distractor repetition. In particular, the former accounts predict distractor-repetition benefits while the latter theory does not. Two experiments further explored the distractor-repetition effects. Experiment 1 replicated previous findings. Experiment 2 further showed that distractor-repetition benefits are still observed when the prime-display distractor and the probe-display target are not correlated. The pattern of results is consistent both with inhibition-based and with retrieval-based accounts of NP, but the results are inconsistent with temporal-discrimination theory.
