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 ...
Additional research proposes the notion of a moveable filter. The multimode theory of attention combines physical and semantic inputs into one theory. Within this model, attention is assumed to be flexible, allowing different depths of perceptual analysis. [28] Which feature gathers awareness is dependent upon the person's needs at the time. [3]
The review argues that perceptual load theory has been misconstrued as a hybrid solution to the early selection versus late selection debate, and that it is instead an early selection model: selection occurs because attention is necessary for semantic processing, and the difference between high-load and low-load conditions is a result of the ...
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.
Selective perception may refer to any number of cognitive biases in psychology related to the way expectations affect perception.Human judgment and decision making is distorted by an array of cognitive, perceptual and motivational biases, and people tend not to recognise their own bias, though they tend to easily recognise (and even overestimate) the operation of bias in human judgment by ...
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]
This selective attention allows individuals to prioritize and respond effectively to important or meaningful stimuli in their surroundings. [4] Researchers in psychology and cognitive science study perceptual vigilance to understand how attentional mechanisms operate and how they can be influenced by internal and external factors.
For example, in their 2009 meta-analysis of Selective Exposure Theory, Hart et al. reported that "A 2004 survey by The Pew Research Center for the People & the Press (2006) found that Republicans are about 1.5 times more likely to report watching Fox News regularly than are Democrats (34% for Republicans and 20% of Democrats).
