Attention capacity and task difficulty in visual search.
When a visual search task is very difficult (as when a small feature difference defines the target), even detection of a unique element may be substantially slowed by increases in display set size. This has been attributed to the influence of attentional capacity limits. We examined the influence of attentional capacity limits on three kinds of search task: difficult feature search (with a subt...
متن کاملAuditory and visual attention assessed with PET.
Brain mechanisms involved in the maintenance of attention to auditory and visual stimuli at different spatial locations were assessed using positron emission tomography with [15O]water to measure regional cerebral blood flow (rCBF) changes in 13 normal volunteers. Simultaneous auditory [dichotically presented consonant-vowel-consonants (CVCs)] and visual stimuli (vertically oriented, CVCs prese...
متن کاملVisual search and selective attention
Visual search is a key paradigm in attention research that has proved to be a test bed for competing theories of selective attention. The starting point for most current theories of visual search has been Treisman’s ‘‘feature integration theory’’ of visual attention (e.g., Treisman & Gelade, 1980). A number of key issues that have been raised in attempts to test this theory are still pertinent ...
متن کاملLifespan Changes in Attention: the Visual Search Task
There are two popular frameworks for the study of visual attention. Treisman’s Feature Integration Theory focuses on the effortful process of binding together the multiple attributes of an object. Posner’s Visual Orienting Theory emphasizes the movement of an attentional spotlight across space. Although both aspects are undoubtedly important in any visual search task, it is not clear how each o...
متن کاملLinguistic cued attention in children: Words organize attention to shape in a visual search task
By one account of early word learning, children become proficient word learners as a result of environmental regularities: Learning words tunes the child to the regularities offered by the language being learned, orienting attention to those regularities. We test one core claim of this account, that count nouns should cue attention to the shape of the objects. Using a visual search task we pres...
