Is All Sparing Created Equal? Comparing Lag-1 Sparing and Extended Sparing in Temporal Object Perception
Visser, Troy A. W.; Ohan, Jeneva L.
Journal of Experimental Psychology: Human Perception and Performance, v37 n5 p1527-1541 Oct 2011
When two targets (T1, T2) are presented amongst a rapid stream of distractors, T2 accuracy is impaired if the targets are separated by at least one distractor (attentional blink). However, this impairment largely disappears if the targets follow one another directly (lag-1 sparing), and, in fact, as many as four or five consecutive targets may be identified quite accurately under these conditions (extended sparing). Although all current models propose a common mechanism for both lag-1 and extended sparing, this hypothesis has yet to be tested. To this end, we examined the effect of various types of attentional switches, known to impact lag-1 sparing, on extended sparing in order to determine whether they would have a similar effect. Results suggested substantial parallels between the two types of sparing. We discuss these results in terms of a unified account of sparing in temporal object perception. (Contains 6 figures.)
