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 ...
Early selection models emphasize physical features of stimuli are attended to, while late selection models argue that semantic features are what determine our current focus of attention. [18] These selection models are utilized by researchers to propose when stimulus information is attended to.
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 ...
This debate became known as the early-selection vs. late-selection models. In the early selection models (first proposed by Donald Broadbent ), attention shuts down (in Broadbent's model ) or attenuates (in Treisman's refinement ) processing in the unattended ear before the mind can analyze its semantic content.
Auditory attention in regards to the cocktail party effect primarily occurs in the left hemisphere of the superior temporal gyrus, a non-primary region of auditory cortex; a fronto-parietal network involving the inferior frontal gyrus, superior parietal sulcus, and intraparietal sulcus also accounts for the acts of attention-shifting, speech processing, and attention control.
A 2023 study shows that having a hobby in midlife and late in life was associated with a lower risk of dementia. Having an engaging chat — say, about your intrinsic beliefs or current events ...
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.
Los Angeles Times owner Patrick Soon-Shiong, who blocked the newspaper’s endorsement of Kamala Harris and plans to overhaul its editorial board, says he will implement an artificial intelligence ...
