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.
When considering the nature and effects of object-based attention, [9] three research theories are commonly mentioned; [10] these are presented below. Consideration is then given to the enhancing effect of object-based attention on memory, and its inhibitory effect during certain kinds of visual 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.
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 ...
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]
Unincorporated visual displays of information, such as the image above, can be distracting and confusing for the user, aside from producing the split-attention effect. [8] The split-attention effect is an important form of extraneous cognitive load that instructional material designers should avoid.
The journal publishes articles on topics such as the visual arts, creativity, crafts, design and art history in educational contexts and learning situations. According to the Journal Citation Reports, the journal has a 2011 impact factor of 0.218, ranking it 181st out of 206 journals in the category "Education & Educational Research". [1]
