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 process of frequency illusion is inseparable from selective attention, due to the cause-and-effect relationship between the two, so the "frequent" object, phrase, or idea has to be selective. This means that a particularly triggering or emotive stimulus could catch someone's attention, possibly more than a mundane task they are preoccupied ...
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 ...
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.
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.
However, beyond this, the mechanisms of attentional bias is an uncertain area, as there are many conflicting theories on how attentional biases operate. [1] An initial theory was schema theory, in which it was believed schema was biased towards threats, thus threat-related material is always favored in cognitive thinking. [29]
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]
Distractor inhibition model with selective attention and encoding process. Distractor inhibition model is the oldest model that explains the negative priming effect as the result of selective attention to a target stimulus. When we pay attention to a particular stimulus, we perceive other stimuli surrounding the target as distractors in order ...
