An influencing element is that an object-like representation can engage attention even when it is not the intended target of a visual search. [19] Therefore, an important consideration is that the perceptual resemblance between distractors and a target object influences the efficiency of visual search ; increases in similarity among the ...
Visual search is a type of perceptual task requiring attention that typically involves an active scan of the visual environment for a particular object or feature (the target) among other objects or features (the distractors). [1] Visual search can take place with or without eye movements.
The preattentive process, as Wolfe explains, directs attention in both a bottom-up and top-down way. Information acquired through both bottom-up and top-down processing is ranked according to priority. The priority ranking guides visual search and makes the search more efficient. Whether the Guided Search Model 2.0 or the feature integration ...
Biased competition theory advocates the idea that each object in the visual field competes for cortical representation and cognitive processing. [1] This theory suggests that the process of visual processing can be biased by other mental processes such as bottom-up and top-down systems which prioritize certain features of an object or whole items for attention and further processing.
MĪller and Kleinschmidt (2003) [18] looked at the early retinotopic visual areas to see if they play a role in object-based attention. They found that when an individual focused on a spatial cued there was retinotopic activity in the V1, V2 , V3 and V4 areas that represented locations outside the cued region, suggesting that information from ...
Information that has the highest salience (a stimulus that stands out the most) or relevance to what a person is thinking about is selected for further and more complete analysis by conscious (attentive) processing. [1] [2] Understanding how pre-attentive processing works is useful in advertising, in education, and for prediction of cognitive ...
Visual spatial attention is a form of visual attention that involves directing attention to a location in space. Similar to its temporal counterpart visual temporal attention , these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable explanation [ 1 ] [ 2 ...
Visual temporal attention is a special case of visual attention that involves directing attention to specific instant of time. Similar to its spatial counterpart visual spatial attention , these attention modules have been widely implemented in video analytics in computer vision to provide enhanced performance and human interpretable ...
