The models of attention proposed prior to Lavie's theory differed in their proposals for the point in the information processing stream where the selection of target information occurs, leading to a heated [3] debate about whether the selection occurs "early" or "late".
Such studies reveal the surprising extent of inattentional blindness - the failure to notice unusual and salient events in their visual world when attention is otherwise engaged and the events are unexpected. Other active research interests include scene perception, object recognition, visual memory, visual fading, attention, and driving and ...
Cognitive psychology is the scientific study of human mental processes such as attention, language use, memory, perception, problem solving, creativity, and reasoning. [1] Cognitive psychology originated in the 1960s in a break from behaviorism , which held from the 1920s to 1950s that unobservable mental processes were outside the realm of ...
[1]: 1 A classic example of a cuing study undertaken to evaluate object-based attention was that of Egly, Driver, and Rafal. [6] Their results demonstrated that it was quicker to detect a target that was located on a cued object than it was to locate the target when it was the same distance away, but on an uncued object.
Voluntary attention, otherwise known as top-down attention, is the aspect over which we have control, enabling us to act in a goal-directed manner. [14] In contrast, reflexive attention is driven by exogenous stimuli redirecting our current focus of attention to a new stimulus, thus it is a bottom-up influence. These two divisions of attention ...
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.
Active perception is the selecting of behaviors to increase information from the flow of data those behaviors produce in a particular environment. In other words, to understand the world, we move around and explore it—sampling the world through our senses to construct an understanding (perception) of the environment on the basis of that behavior (action). [1]
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.
