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]
The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
Additional research proposes the notion of a moveable filter. The multimode theory of attention combines physical and semantic inputs into one theory. Within this model, attention is assumed to be flexible, allowing different depths of perceptual analysis. [28] Which feature gathers awareness is dependent upon the person's needs at the time. [3]
Developed research and applied studies in which this theory has been tested has led to the development of specific conditions required for the excitation-transfer process to occur. These conditions include time, shift of attention and hedonic assimilation. [1] Examples of how the theory is applied are also provided.
The scarcity of attention is the underlying assumption for attention management; the researcher Herbert A. Simon pointed out that when there is a vast availability of information, attention becomes the more scarce resource as human beings cannot digest all the information. [6] Fundamentally, attention is limited by the processing power 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.
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.
In attention research, one prominent theory attempting to explain how visual attention is shifted is the moving-spotlight theory. The primary idea being that attention is like a movable spotlight that is directed towards intended targets, focusing on each target in a serial manner.
