![]() Broadbent proposed that auditory information enters an unlimited sensory buffer and that one stream of information is filtered out and passes through the bottleneck to be cohesive, while all others that are not selected quickly decay in salience and are not processed. Broadbent theorized that the human information processing system has a "bottleneck" due to limited capacity and that the brain performs an "early selection" before processing auditory information. 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. Though introduced by Colin Cherry, Donald Broadbent is often regarded as the first to systematically apply dichotic listening tests in his research. This was later termed the dichotic listening task. ![]() In Cherry's experiment, mimicking the problem faced by air traffic controllers, participants had to listen to two messages played simultaneously from one loudspeaker and repeat what they heard. Hearing mixed voices through a single loudspeaker made the task very difficult. At the time, air traffic controllers at the control tower received messages from pilots through loudspeakers. There have been some models that theorize the pathway of selective auditory attention, notably the early selection model, late selection model, and attenuation model.Įarly researches on selective auditory attention can be traced back to 1953, when Colin Cherry introduced the " cocktail party problem". ![]() A brain simply cannot process all sensory information that is occurring in an environment so only the most relevant and important information is thoroughly processed by the brain. This is an example of bottlenecking which means that information cannot be processed simultaneously so only some sensory information gets through the "bottleneck" and is processed. An example of this is a student focusing on a teacher giving a lesson and ignoring the sounds of classmates in a rowdy classroom (p. 53). In an article by Krans, Isbell, Giuliano, and Neville (2013), selective auditory attention is defined as the ability to acknowledge some stimuli while ignoring other stimuli that is occurring at the same time. Selective auditory attention differs from selective perception, in that the filtering in the latter case is mediated by cognitive dissonance. The dividing line between preference and utility is not clear cut. ![]() It is the notion of ignoring certain things in the surrounding environment. Selective hearing is not a physiological disorder but rather it is the capability of humans to block out sounds and noise. Most often, auditory attention is directed at things people are most interested in hearing. When people use selective hearing, noise from the surrounding environment is heard by the auditory system but only certain parts of the auditory information are chosen to be processed by the brain. Selective hearing is characterized as the action in which people focus their attention intentionally on a specific source of a sound or spoken words. Selective auditory attention or selective hearing is a type of selective attention and involves the auditory system.
