Dissociations between identity and location negative priming.

Negative priming refers to the phenomenon of a slowed response time to a previously ignored distractor. Identity negative priming can be observed when the identity of a previous distractor is repeated as the target identity, and location negative priming can be observed when the spatial location of a previous distractor is repeated as the target location. This article reviewed and integrated previous findings and provided empirical evidence to show the dissociations between location and identity negative priming: (a) the removal of probe distractor impeded identity negative priming but not location negative priming; (b) identity negative priming was modulated by the distance between the target and distractor, while location negative priming was not; and (c) perceptual grouping of the target and distractor affected identity negative priming but not location negative priming.
