The early selection model of attention, proposed by Broadbent, [1] posits that stimuli are filtered, or selected to be attended to, at an early stage during processing. A filter can be regarded as the selector of relevant information based on basic features, such as color, pitch, or direction of stimuli.
Broadbent's filter model is referred to as an Early Selection Model because irrelevant messages are filtered out BEFORE the stimulus information is processed for meaning. These and other theories were brought together in his 1958 book Perception and Communication, which remains one of the classic texts of cognitive psychology. [7]
Treisman's attenuation model of selective attention retains both the idea of an early selection process, as well as the mechanism by which physical cues are used as the primary point of discrimination. [4] However, unlike Broadbent's model, the filter now attenuates unattended information instead of filtering it out completely. [1]
Deutsch & Deutsch's late selection model that was proposed in 1963 is a competing model to Broadbent's early selection model. [12] Deutsch & Deutsch's model theorizes that all information and sensory input are attended to and processed for meaning. [12]
An 11,000-year-old Indigenous settlement found in Saskatchewan reshapes the understanding of North American civilizations. Evidence of a long-term settlement, rather than a temporary hunting camp ...
The earliest work in exploring mechanisms of early selective attention was performed by Donald Broadbent, who proposed a theory that came to be known as the filter model. [24] This model was established using the dichotic listening task.
Hydeia Broadbent, a prominent HIV/AIDS activist who gained media attention for being a part of America’s “first generation of children born HIV positive” in the late 1980s, died Tuesday.
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.
