Temporal Pacing in Visual Attention.
Abstract
Viewers engaged in a continuous letter classification task involving selective attending to one of two information streams (relevant and irrelevant). Temporal and spatial relations were systematically varied between the two streams to address hypotheses about external control of attention in dynamic environments. Relative event timing was varied both within and between the two streams. Spatial relationships for relevant and irrelevant events was the same for experiments 1 & 3, but different for experiment 2. Contrary to predictions from either spatial or object oriented approaches, attending and hence, performance, to relevant events in all three experiments was dependent on the integrated rhythmic patterns that obtained between the two streams, rather than spatial location and event features. Several alternative hypotheses addressed the issue of non-spatial control of attending to dynamic displays, The best account assumes viewer attending is 'paced' by rhythms emerging from an integration of relevant and irrelevant event streams.
