  • Title: Time course of attention effects with abrupt-onset and offset single- and multiple-element precues.
    Author: Chastain G, Cheal M.
    Journal: Am J Psychol; 1999; 112(3):411-36. PubMed ID: 10696272.
    Abstract:
    Large differences between the time course of attentional responsiveness to onset single-element precues (onset singles) and to onset multiple-element precues (onset multiples) have suggested differences in the way attention is controlled. In five experiments here, singles presented as offsets produced rapid attention buildup, attentional decay across longer precue-to-target delays, and attentional capture, as do onset singles, suggesting exogenous attentional control; both offset and onset multiples produced gradual onset of attentional effects without subsequent attentional decay, suggesting endogenous attentional control; and onset and offset singles produced higher accuracy than onset and offset multiples. Thus, the dynamic quality of a sudden onset is not sufficient explanation for the exogenous attentional control produced by a single-element peripheral precue.
