Three visual-search experiments tested whether the preattentive parallel stage can-
selectively guide the attentive stage to a particular known-to-be-relevant target feature …

Three visual search experiments tested whether top-down selectivity toward particular
stimulus dimensions is possible during preattentive parallel search. Subjects viewed …

Most theories of visual search emphasize issues of limited versus unlimited capacity and
serial versus parallel processing. In the present article, we suggest a broader framework …

Test targets ('singletons') that displayed orientation, motion, luminance, or color contrast, or
pairwise combinations of these, were presented in line texture arrays, and their saliences …

To explain the surprisingly high frequency of congenital red–green colour blindness, the
suggestion has been made that dichromats might be at an advantage in breaking certain …

Abstract revision accepted for publication October 2, 1987. How do different dimensions (eg,
color and form) interact when the visual system locates boundaries in surfaces? Seven …

The mental representations of perceptual and cognitive stimuli vary on many dimensions. In
addition, because of quantal fluctuations in the stimulus, spontaneous neural activity, and …

An experiment examined cross-modal interference and congruence in speeded
classification: Subjects had to identify compound (visual-auditory) stimuli as either low or …

Both the sudden appearance of an object and sudden changes in existing object features
influence priority in visual search. However, direct comparisons of these influences have not …

Most psychological, physiological, and computational models of early vision suggest that
retinal information is divided into a parallel set of feature modules. The dominant theories of …
