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.
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.
Capacity theory is the theoretical approach that pulled researchers from Filter theories with Kahneman's published 1973 study, Attention and Effort positing attention was limited in overall capacity, that a person's ability to perform simultaneous tasks depends on how much "capacity" the jobs require. Further researchers - Johnson and Heinz ...
The PASS theory provides the theoretical framework for a measurement instrument called the Das-Naglieri Cognitive Assessment System (CAS), published in 1997. [6] This test, now in a Second Edition (CAS2; 2014, Naglieri, Das & Gold-stein) is designed to provide an assessment of intellectual functioning redefined as four brain-based cognitive processes (Planning, Attention, Simultaneous and ...
Anne Marie Treisman (née Taylor; 27 February 1935 – 9 February 2018) was an English psychologist who specialised in cognitive psychology. Treisman researched visual attention, object perception, and memory. One of her most influential ideas is the feature integration theory of attention, first published with Garry Gelade in 1980.
The review argues that perceptual load theory has been misconstrued as a hybrid solution to the early selection versus late selection debate, and that it is instead an early selection model: selection occurs because attention is necessary for semantic processing, and the difference between high-load and low-load conditions is a result of the ...
The brain not only uses the process of attention, but it also builds a set of information, or a representation, descriptive of attention. That representation, or internal model, is the attention schema. In the theory, the attention schema provides the requisite information that allows the machine to make claims about consciousness.
For example, pre-attentive processing is slowed by sleep deprivation while attention, although less focused, is not slowed. [6] Furthermore, when searching for a particular visual stimulus among a variety of visual distractions, people often have more trouble finding what they are looking for if one or more of the distractions is particularly ...
