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 of attention proposed that the physical characteristics (e.g., pitch, loudness) of an auditory message were used to focus attention to only a single message. 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 ...
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. [3] However, unlike Broadbent's model, the filter now attenuates unattended information instead of filtering it out completely. [1]
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. His research showed that most participants were accurate in recalling information that they actively ...
Broadbent used the method of dichotic listening to test how participants selectively attend to stimuli when overloaded with auditory stimuli; Broadbent used his findings to develop the filter model of attention in 1958. [9] Broadbent theorized that the human information processing system has a "bottleneck" due to limited capacity and that the ...
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.
