How is attention guided by past experience? In visual search, numerous studies have shown that recent trials influence responses to the current trial. Repeating features such as color, shape, or location of a target facilitates performance. Here we examine whether recent experience also modulates a more abstract dimension of attentional control,…

J. S. Joseph, M. M. Chun, and K. Nakayama (1997) found that pop-out visual search was impaired as a function of intertarget lag in an attentional blink (AB) paradigm in which the 1st target was a letter and the 2nd target was a search display. In 4 experiments, the present authors tested the implication that search efficiency should be similarly…

What happens after visual attention is allocated to an object? Although many theories of attention assume that all of its features are selected and processed, there has been little direct evidence that an irrelevant feature dimension of an attended nontarget is processed. In 5 experiments presented here, the authors used a singleton paradigm to…

Letter pairs that could not be distinguished by learning disabled children were presented using an acquisition-reversal learning paradigm. Relevant external stimuli facilitated discrimination; in reversal, the cues were irrelevant. This technique facilitated learning, as well as retention four days later. (Attentional deficits are discussed). (GDC)

Two experiments studied whether altering an auditory stimulus' rate of change affected infants' fixation of changing visual stimuli. Results demonstrated that infants exposed simultaneously to auditory and visual stimulation showed a reduced tendency to fixate on relatively more visually stimulating events. Heart rates also accelerated during…
