Sources of attention in the brain create a system of three networks: alertness (maintaining awareness), orientation (information from sensory input), and executive control (resolving conflict). [2] These three networks have been studied using experimental designs involving adults, children, and monkeys, with and without abnormalities of ...
Selective auditory attention is a normal sensory process of the brain, and there can be abnormalities related to this process in people with sensory processing disorders such as autism, attention deficit hyperactive disorder, [30] post traumatic stress disorder, [31] schizophrenia, [30] selective mutism, [32] and in stand-alone auditory ...
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 visual attention acts to 'bias' this competition in favour of certain selected features or representations. For example, imagine that you are waiting at a busy train station for a friend who is wearing a red coat. You are able to selectively narrow the focus of your attention to search for red objects, in the hope of identifying your ...
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.
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.
This was one of the first papers to show that attention could modulate a visually evoked potential as early on as the P1. Ever since this experiment, the difference between the P1 amplitude when the participant is attending in the correct and incorrect visual field (or the P1 effect) has been extensively studied as part of selective attention. [4]
N2pc refers to an ERP component linked to selective attention. [1] The N2pc appears over visual cortex contralateral to the location in space to which subjects are attending; if subjects pay attention to the left side of the visual field, the N2pc appears in the right hemisphere of the brain, and vice versa.
