More recent research finds that Broadbent's model neglected to address the time requirements of shifting attention. [4] However, he did distinguish that internal and external stimuli can cause shifts of attention, though he did not consider that internally and externally driven shifts of attention may have differing time courses.

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 ...
The "dichotic fused words test" (DFWT) is a modified version of the basic dichotic listening test. It was originally explored by Johnson et al. (1977) [25] but in the early 80's Wexler and Hawles (1983) [26] modified this original test to ascertain more accurate data pertaining to hemispheric specialization of language function.
The person's speech seems to indicate that their attention to their own speech has perhaps in some way been overcome during the occurrence of cognition whilst speaking, causing the vocalized content to follow thought that is apparently without reference to the original idea or question; or the person's speech is considered evasive in that the ...
A late talker is a toddler experiencing late language emergence (LLE), [2] [3] which can also be an early or secondary sign of an autism spectrum disorder, or other neurodevelopmental disorders such as fetal alcohol spectrum disorder, attention deficit hyperactivity disorder, intellectual disability, learning disability, social communication disorder, or specific language impairment.
Donald Eric (D. E.) Broadbent CBE, [1] FRS [2] (Birmingham, 6 May 1926 – 10 April 1993) [3] was an influential experimental psychologist from the United Kingdom. [4] His career and research bridged the gap between the pre-World War II approach of Sir Frederic Bartlett [5] and what became known as cognitive psychology in the late 1960s.
In 1958, Donald Broadbent proposed the filter model of attention. [5] Selective attention of vision was studied in the 1960s by George Sperling's partial report paradigm. It was also noticed that saccade control is modulated by cognitive processes, insofar as the eye moves preferentially towards areas of high salience. As the fovea of the eye ...
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 ...
