Attention is best described as the sustained focus of cognitive resources on information while filtering or ignoring extraneous information. Attention is a very basic function that often is a precursor to all other neurological/cognitive functions. As is frequently the case, clinical models of attention differ from investigation models.
The effect of object-based attention on memory has also received increasing attention. Three experiments conducted by Bao and colleagues have shown that the binding of different information to a single object improves the manipulation of that information within working memory, suggesting a relationship between outer visual attention and ...
The process of frequency illusion is inseparable from selective attention, due to the cause-and-effect relationship between the two, so the "frequent" object, phrase, or idea has to be selective. This means that a particularly triggering or emotive stimulus could catch someone's attention, possibly more than a mundane task they are preoccupied ...
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.
[10] [11] This pupil dilation effect is discussed to indicate a detection of stimulus salience [12] and is expected to amplify the sensory processing of the salient stimulus by increased neural gain. [13] [14] The perception of time seems to be modulated by our recent experiences. Humans typically overestimate the perceived duration of the ...
Salience bias acts to combat cognitive overload by focusing attention on prominent stimuli, which affects how individuals perceive the world as other, less vivid stimuli that could add to or change this perception, are ignored. Human attention gravitates towards novel and relevant stimuli and unconsciously filters out less prominent information ...
The following process connects a person's concepts and expectations (or knowledge) with restorative and selective mechanisms, such as attention, that influence perception. Perception depends on complex functions of the nervous system, but subjectively seems mostly effortless because this processing happens outside conscious awareness. [3]
Attentional bias refers to how a person's perception is affected by selective factors in their attention. [1] Attentional biases may explain an individual's failure to consider alternative possibilities when occupied with an existing train of thought. [2]
