Attenuation theory, also known as Treisman's attenuation model, is a theory of selective attention proposed by psychologist Anne Treisman that explains how the mind processes sensory input by weakening (attenuating) unattended stimuli rather than fully blocking them. [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.
Anne Treisman, though influenced by Broadbent's work, was not fully convinced by the notion of a filter performing decisions as to what stimuli gain conscious awareness. She proposed an alternative mechanism, attenuation theory. This theory supports an early-selection filter.
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.
A "hugely influential" [76] theory regarding selective attention is the perceptual load theory, which states that there are two mechanisms that affect attention: cognitive and perceptual. The perceptual mechanism considers the subject's ability to perceive or ignore stimuli, both task-related and non task-related.
Treisman also suggests that a threshold mechanism exists in selective auditory attention in which words from the unattended stream of information can grab one's attention. Words of low threshold, higher level of meaning and importance, such as one's name and "watch out", redirects one's attention to where it is urgently required.
Major process theories are expectancy theory, equity theory, goal-setting theory, self-determination theory, and reinforcement theory. [123] Another way to classify theories of motivation focuses on the role of inborn physiological processes in contrast to cognitive processes and distinguishes between biological, psychological, and ...
