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.
Research attention is currently focused not only on external perception processes, but also to "interoception", considered as the process of receiving, accessing and appraising internal bodily signals. Maintaining desired physiological states is critical for an organism's well-being and survival.
Their research suggests that consumers specifically direct their attention to products with eye-catching properties such as shape, colour or brand name. This effect is due to a pressured visual search where eye movements accelerate and saccades minimise, thus resulting in the consumer's quickly choosing a product with a 'pop out' effect.
Feature integration theory is a theory of attention developed in 1980 by Anne Treisman and Garry Gelade that suggests that when perceiving a stimulus, features are "registered early, automatically, and in parallel, while objects are identified separately" and at a later stage in processing.
Additionally, global interference effect, which occurs when the global aspect is automatically processed even when attention is directed locally, causes slow reaction time. [2] Navon's study global precedence and his stimuli, or variations of it, are still used in nearly all global precedence experiments.
These contrasting effects between attending-to-others and attending-to-self prompt a synthetic view in a recent Opinion article [116] proposing that social attention operates at two polarizing states: In one extreme, individual tends to attend to the self and prioritize self-related information over others', and, in the other extreme, attention ...
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.
Only then, the subject of Crowding found increasingly wide attention in visual perception research (Levi et al. 1985; Strasburger et al., 1991; Toet & Levi, 1992, Pelli et al., 2004). [24] Today, it is a major topic in vision and perception and is increasingly recognized for being the major limitation of foveal and peripheral form perception.
