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 ...
To demonstrate this effect they created a video where students pass a basketball between themselves. Viewers asked to count the number of times the players with the white shirts pass the ball often fail to notice a person in a gorilla suit who appears in the center of the image (see Invisible Gorilla Test ), an experiment described as "one of ...
Selective auditory attention, or selective hearing, is a process of the auditory system where an individual selects or focuses on certain stimuli for auditory information processing while other stimuli are disregarded. [1] This selection is very important as the processing and memory capabilities for humans have a limited capacity. [2]
A "hugely influential" [76] theory regarding selective attention is the perceptual load theory, which states that there are two mechanisms that affect attention: cognitive and perceptual. The perceptual mechanism considers the subject's ability to perceive or ignore stimuli, both task-related and non task-related.
The eye-contact effect is a psychological phenomenon in human selective attention and cognition. It is the effect that the perception of eye contact with another human face has on certain mechanisms in the brain. [1] This contact has been shown to increase activation in certain areas of what has been termed the ‘social brain’. [2]
Selective attention in humans had been well studied in neuroscience and cognitive psychology. [3] In 1953, Colin Cherry studied selective attention in the context of audition, known as the cocktail party effect. [4] In 1958, Donald Broadbent proposed the filter model of attention. [5]
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.
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.
