  2. Visual search - Wikipedia

    en.wikipedia.org/wiki/Visual_search

    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.

  3. Object-based attention - Wikipedia

    en.wikipedia.org/wiki/Object-based_attention

    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 ...

  4. Feature integration theory - Wikipedia

    en.wikipedia.org/wiki/Feature_integration_theory

    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 ...

  5. Biased competition theory - Wikipedia

    en.wikipedia.org/wiki/Biased_Competition_Theory

    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.

  6. Pre-attentive processing - Wikipedia

    en.wikipedia.org/wiki/Pre-attentive_processing

    For example, pre-attentive processing is slowed by sleep deprivation while attention, although less focused, is not slowed. [6] Furthermore, when searching for a particular visual stimulus among a variety of visual distractions, people often have more trouble finding what they are looking for if one or more of the distractions is particularly ...

  7. Split attention effect - Wikipedia

    en.wikipedia.org/wiki/Split_attention_effect

    The figure on the left side of the image produces the split-attention effect, while the figure on the right enhances learning because it guides the learner's attention through the worked example. Unincorporated visual displays of information, such as the image above, can be distracting and confusing for the user, aside from producing the split ...

  8. Perceptual learning - Wikipedia

    en.wikipedia.org/wiki/Perceptual_learning

    Studies of perceptual learning with visual search show that experience leads to great gains in sensitivity and speed. In one study by Karni and Sagi, [ 3 ] the time it took for subjects to search for an oblique line among a field of horizontal lines was found to improve dramatically, from about 200ms in one session to about 50ms in a later session.
