The role of selection in generating auditory negative priming.

The importance of selecting between a target and a distractor in producing auditory negative priming was examined in three experiments. In Experiment 1, participants were presented with a prime pair of sounds, followed by a probe pair of sounds. For each pair, listeners were to identify the sound presented to the left ear. Under these conditions, participants were especially slow to identify a sound in the probe pair if it had been ignored in the preceding prime pair. Evidence of auditory negative priming was also apparent when the prime sound was presented in isolation to only one ear (Experiment 2) and when the probe target was presented in isolation to one ear (Experiment 3). In addition, the magnitude of the negative priming effect was increased substantially when only a single prime sound was presented. These results suggest that the emergence of auditory negative priming does not depend on selection between simultaneous target and distractor sounds.
