A theory is presented that attempts to answer two questions. What visual contents can an
observer consciously access at one moment? Answer: only one feature value (eg, green) …

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 …

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 Three central problems in the recent literature on visual attention are reviewed.
The first concerns the control of attention by top-down (or goal-directed) and bottom-up (or …

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 …

Models of visual attention have, with few exceptions, suggested that attention is deployed to
unitary regions of visual space. Kramer and Hahn (1995) recently reported that attention is …

A great deal of evidence has accumulated over the last 20 years or so suggesting that
decisions concerning the contents of a visual. scene can be enhanced with the assistance of …

Much of the research in visual attention has been driven by the spotlight metaphor. This
metaphor has been useful over many years for generating experimental questions in …

The present paper outlines a framework which allows a consistent interpretation of data
regarding visual selection in visual search tasks. It organizes and reviews visual search …

A new hypothesis about the role of focused attention is proposed. The feature-integration
theory of attention suggests that attention must be directed serially to each stimulus in a …
