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 ...
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.
It is held that the order of a visual search is important in the manifestation of object-based effects. The object-based attentional advantage could be mediated by increased attentional priority assigned to locations within an already attended object, namely, where a visual search starts by default from locations within an already attended object.
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.
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.
The Trail Making Test is a neuropsychological test of visual attention and task switching.It has two parts, in which the subject is instructed to connect a set of 25 dots as quickly as possible while maintaining accuracy. [1]

Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context.
