Attenuation theory, also known as Treisman's attenuation model, is a model of selective attention proposed by Anne Treisman, and can be seen as a revision of Donald Broadbent's filter model. Treisman proposed attenuation theory as a means to explain how unattended stimuli sometimes came to be processed in a more rigorous manner than what ...
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.
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.
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.
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.
In order to explain the IOR mechanism, Anne Treisman and Gary Gelade's theory of visual search was expounded. This theory, known as the feature integration theory proposes that there are two types of visual searches: parallel searches and serial searches. [4] According to Treisman and Gelade, attention is only required for serial searches.

The umwelt theory states that the mind and the world are inseparable because it is the mind that interprets the world for the organism. Because of the individuality and uniqueness of the history of every single organism, the umwelten of different organisms differ.
