Conducted 4 experiments with 108 volunteers (aged 18-42 yrs) to test object-, discrimination-
, and space-based theories of visual attention. In each experiment, Ss were presented with …

Investigated in 2 experiments whether attentional resources can be simultaneously
allocated to several locations in a visual display, whether the mode of processing (serial or …

RM Shiffrin et al (see record 1976-09003-001) reported no effect of selective-attention
instructions on a perceptual task, despite studies by BE Butler and PM Merikle (see record …

Previous studies have shown that simple reaction times (RTs) to a visual target are
facilitated when the target occurs at a location expected by an observer and are slowed …

Abstract RESEARCH ON SELECTIVE ATTENTION IN HUMANS IS DISCUSSED
CRITICALLY. EMPHASIS IS PLACED ON AN ANALYSIS OF THE NATURE OF THE …

The influence of the Gestalt grouping principles of similarity, closure, and proximity on the
size of the response-compatibility effect was examined in a focused attention task. In three …

Accuracy is of ten reduced when two visual discriminations must be made concurrently
(“divided attention”). According to a hypothesis originally proposed by Treisman (1969) and …

In 3 studies with 20 undergraduates and staff, Ss viewed 3× 3 grids in which different
subsets of the 9 squares were designated as" figure," either by physical shading of those …

A new test was devised to avoid previous confounds in measures of object-based limits on
divided visual attention. The distinction between objects was manipulated across a wide …

A unified theory of visual recognition and attentional selection is developed by integrating
the biased-choice model for single-stimulus recognition (RD Luce, 1963; RN Shepard …
