Attention is best described as the sustained focus of cognitive resources on information while filtering or ignoring extraneous information. Attention is a very basic function that often is a precursor to all other neurological/cognitive functions. As is frequently the case, clinical models of attention differ from investigation models.
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 updating function is used to update and monitor information in working memory. [37] [38] There are three main hypotheses associated with attentional control theory. First, the efficiency of the central executive is impaired by anxiety. Second, anxiety impairs the inhibition function, and third, anxiety impairs the shifting function. [39]
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 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.
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]
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]
Dichotic listening is a psychological test commonly used to investigate selective attention and the lateralization of brain function within the auditory system.It is used within the fields of cognitive psychology and neuroscience.
