Given a stimulus that requires combining features, people with Balint's syndrome are unable to focus attention long enough to combine the features, providing support for this stage of the theory. [5] The stages of feature integration theory. Treisman distinguishes between two kinds of visual search tasks, "feature search" and "conjunction 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.
In psychology, contextual cueing refers to a form of visual search facilitation which describe targets appearing in repeated configurations are detected more quickly. The contextual cueing effect is a learning phenomenon where repeated exposure to a specific arrangement of target and distractor items leads to progressively more efficient search.
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 ...
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 ...
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.

A majority of experiments highlights a role of human posterior parietal cortex in visual working memory and attention. We therefore have to establish a clear separation of visual memory and attention from processes related to the planning of goal-directed motor behaviors. We can only hold in mind a minute fraction of the visual scene.
