Feature integration without visual attention: Evidence from the correlated flankers task
- PsychologyPsychonomic bulletin & review
A more specific test was conducted and found strong evidence in favor of feature integration in the absence of attention, raising the possibility that attention is not required for feature integration, per se, but is only required when color-shape conjunctions must undergo an arbitrary S-R translation.
Feature Integration Theory
- Psychology, BiologyEncyclopedia of Animal Cognition and Behavior
There are many ecological reasons, and now ample evidence, to support the argument that feature integration theory is universal and relevant to many animal species too.
A theory of visual attention.
- Psychology, BiologyPsychological review
A unified theory of visual recognition and attentional selection is developed by integrating the biased-choice model for single-stimulus recognition with a choice model for selection from multielement displays in a race model framework.
Theory of attentional operations in shape identification.
This article presents a theory of selective attention that is intended to account for the identification of a visual shape in a cluttered display. The selected area of attention is assumed to be…
Feature-based attentional integration of color and visual motion.
- Psychology, BiologyJournal of vision
Throughout, reaction times to simultaneous presentations of color and direction targets were too fast to be reconciled with models proposing separate and independent processing of such stimulus dimensions, arguing against object- and location-based accounts of attentional selection in such a task.
Perceptual grouping and attention in visual search for features and for objects.
- PsychologyJournal of experimental psychology. Human perception and performance
The effects of perceptual grouping on search for targets defined by separate features or by conjunction of features is explored, suggesting that preattentive grouping creates separate feature maps within each separable dimension rather than one global configuration.
Detecting conjunctions of color and form in parallel
- PsychologyPerception & psychophysics
In the three experiments reported here, a redundant-target detection task was used with conjunctively defined targets and display sizes of two, one or two, and six, and strong evidence for parallel processing was observed.
Pre-Attentive and Attentive Visual Information Processing
The weight of the evidence suggests that feature identification can be carried out by spatially parallel processes, but semantic categorization of words cannot.

Towards a resolution theory of visual attention.
- Computer Science
A selective review of the literature shows that the proposed distinction is supported by a variety of studies investigating diverse phenomena of target-background similarity effects, conjunctive search, illusory conjunctions, feature similarity effects), shape discrimination, detection of signals, categorical search, curvature discrimination, and length perception.

It is shown that performance in situations of this type is analogous to that in which subjects respond to groups of stimuli rather than to particular items, and stimulus and response entropy are independently varied.
Interactions of signal and background variables in visual processing

Three variables which determine the opportunities for signal-noise confusions, display size (D), number of redundant signals per display (N), and number of alternative signals (A) were studied in…
Identification and categorization in visual search

Seven experiments were addressed to the general question of whether the identification of letters and numbers is a more rapid process than the categorization of such stimuli, finding that identification reaction times (RTs) were faster than categorization RTs.
A conceptual category effect in visual search: O as letter or as digit
Evidence is presented for a processing mechanism in visual recognition that depends upon how the stimulus array is conceptually categorized rather than upon its physical characteristics. Ss had to…

The main findings were interpreted in terms of a model of perceptual processing which involves mechanisms for hierarchical coding, selective attention, and automatic processing.
