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.
Donald Broadbent based the development of the filter model from findings by Kennith Craik, who took an engineering approach to cognitive processes. Cherry and Broadbent were concerned with the issue of selective attention. [1] Broadbent was the first to describe the human attentional processing system using an information processing metaphor. [2]
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 ...
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]
The brain not only uses the process of attention, but it also builds a set of information, or a representation, descriptive of attention. That representation, or internal model, is the attention schema. In the theory, the attention schema provides the requisite information that allows the machine to make claims about consciousness.
Attentional control theory focuses on anxiety and cognitive performance. The assumption of this theory is that the effects of anxiety on attentional control are key to understanding the relationship between anxiety and performance. In general, anxiety inhibits attentional control on a specific task by impairing processing efficiency. [37]
Also referred to as gating or filtering, sensory gating prevents an overload of information in the higher cortical centers of the brain. Sensory gating can also occur in different forms through changes in both perception and sensation, affected by various factors such as "arousal, recent stimulus exposure, and selective attention." [1]
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 ...
