Selective attentional delays and attentional capture among simultaneous visual onset elements.
Visual discrimination and detection responses to a single stimulus presented simultaneously with noise stimuli are slower and less accurate than are responses to a single stimulus presented alone. This occurs even though the location of the relevant stimulus (target) is known or visually indicated with stimuli onset. Results showed that noise elements delay focal attending and processing of a t...
متن کاملVisual field asymmetry in attentional capture.
The present study examined the spatial distribution of involuntary attentional capture over the two visual hemi-fields. A new experiment, and an analysis of three previous experiments showed that distractors in the left visual field that matched a sought-for target in color produced a much larger capture effect than identical distractors in the right visual field, revealing a visual field asymm...
متن کاملAttentional window and attentional capture 1 THE SIZE OF AN ATTENTIONAL WINDOW MODULATES ATTENTIONAL CAPTURE BY COLOR SINGLETONS
It has been proposed that during visual search a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local shape (focused attention) before starting the search for a non-singleton target. We demonstrate that increa...
متن کاملAttentional and oculomotor capture by onset, luminance and color singletons
In three experiments we investigated whether attentional and oculomotor capture occur only when object-defining abrupt onsets are used as distractors in a visual search task, or whether other salient stimuli also capture attention and the eyes even when they do not constitute new objects. The results showed that abrupt onsets (new objects) are especially effective in capturing attention and the...
متن کاملValue-driven attentional capture.
Attention selects which aspects of sensory input are brought to awareness. To promote survival and well-being, attention prioritizes stimuli both voluntarily, according to context-specific goals (e.g., searching for car keys), and involuntarily, through attentional capture driven by physical salience (e.g., looking toward a sudden noise). Valuable stimuli strongly modulate voluntary attention a...
