Attending, ignoring, and repetition: On the relation between negative priming and inhibition of return

A series of spatial localization experiments is reported that addresses the relation between negative priming and inhibition of return. The results of Experiment 1 demonstrate that slowed responses to repeated location stimul i can be obscured by repetition priming effects involving stimulus dimensio ns other than spatial location. The results of Experiments 2, 3A, and 3B de monstrate that these repetition priming effects may occur only when partici pants are required to respond to the prime display. Together, these results suggest that differences between attended and ignored repetition effects i n selective attention studies of spatial localization do not provide a basi s for distinguishing between spatial negative priming and inhibition of ret urn.
