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 ...
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.
Attention is part of nearly every waking moment for humans, as it is the focusing of one's thoughts. Selective attention [14] utilizes cognitive processes to focus on relevant targets on input, thoughts or actions while neglecting irrelevant sources of input. This is the basis for how we attend to specific stimuli.
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 ...
Attentional bias refers to how a person's perception is affected by selective factors in their attention. [1] Attentional biases may explain an individual's failure to consider alternative possibilities when occupied with an existing train of thought. [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]
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]
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 ...
