Beyond the search surface: visual search and attentional engagement.
Treisman (1991) described a series of visual search studies testing feature integration theory against an alternative (Duncan & Humphreys, 1989) in which feature and conjunction search are basically similar. Here the latter account is noted to have 2 distinct levels: (a) a summary of search findings in terms of stimulus similarities, and (b) a theory of how visual attention is brought to bear o...
متن کاملUncertainty, attentional capacity and chromatic mechanisms in visual search
Two general questions were investigated using a visual search task. First, we asked whether effects of target uncertainty on reaction time varied with the discriminability of the target and distractors. Second, a higher order chromatic mechanism model was tested against a flexible model in which the signals in cardinal color-opponent mechanisms are combined through an attentional process. The m...
متن کاملMultisensory enhancement of attentional capture in visual search.
Multisensory integration increases the salience of sensory events and, therefore, possibly also their ability to capture attention in visual search. This was investigated in two experiments where spatially uninformative color change cues preceded visual search arrays with color-defined targets. Tones were presented synchronously with these cues on half of all trials. Spatial-cuing effects indic...
متن کاملThe neural basis of attentional control in visual search.
How do we localise and identify target objects among distractors in visual scenes? The role of selective attention in visual search has been studied for decades and the outlines of a general processing model are now beginning to emerge. Attentional processes unfold in real time and this review describes four temporally and functionally dissociable stages of attention in visual search (preparati...
متن کاملVisual search attentional bias modification reduced social phobia in adolescents.
BACKGROUND AND OBJECTIVES An attentional bias for negative information plays an important role in the development and maintenance of (social) anxiety and depression, which are highly prevalent in adolescence. Attention Bias Modification (ABM) might be an interesting tool in the prevention of emotional disorders. The current study investigated whether visual search ABM might affect attentional b...
