Perceptual latency priming: A measure of attentional facilitation

Research output: Journal contributionsJournal articlesResearchpeer-review


The present paper reviews recent research on perceptual latency priming (PLP). PLP is the relative latency advantage—earlier perception—of a visual stimulus that is preceded by another, masked stimulus at its location. The first stimulus attracts attention which accelerates perception of the second stimulus. This facilitation arises even if the first stimulus is visually backward-masked by the second one. The paper summarises research on temporal and spatial properties of PLP and the question whether intentions mediate shifts of attention to external events. Possible sources of PLP besides visuo-spatial attention are discussed. Finally, I give a review of feedforward and reentrant models of PLP and compare them to the empirical evidence.
