Covert orienting has the potential to affect the output of perceptual processes by governing attention to particular items or locations (for example, the activity of a V4 neuron whose receptive field lies on an attended stimuli will be enhanced by covert attention) [53] but does not influence the information that is processed by the senses ...
Other areas of the brain associated with sensory gating include the amygdala, striatum, medial prefrontal cortex, and mid-brain dopamine cell region (GABAergic neurons only). Research on sensory gating has been primarily occurring in cortical areas where the stimulus is consciously identified because it is a less invasive means of studying ...
Just like the brain constructs a simplified model of the body to help monitor and control movements of the body, so the brain constructs a simplified model of attention to help monitor and control attention. The information in that model, portraying an imperfect and simplified version of attention, leads the brain to conclude that it has a non ...
Voluntary attention, otherwise known as top-down attention, is the aspect over which we have control, enabling us to act in a goal-directed manner. [14] In contrast, reflexive attention is driven by exogenous stimuli redirecting our current focus of attention to a new stimulus, thus it is a bottom-up influence. These two divisions of attention ...
The psychological definition of attention is "a state of focused awareness on a subset of the available sensation perception information". [12] A key function of attention is to identify irrelevant data and filter it out, enabling significant data to be distributed to the other mental processes. [4]
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways , and parts of the brain involved in sensory perception and interoception .
The “spacing effect” refers to a phenomenon whereby learning, or the creation of a memory, occurs more effectively when information, or exposure to a stimulus, is spaced out.
Perceptual learning is a more in-depth relationship between experience and perception. Different perceptions of the same sensory input may arise in individuals with different experiences or training. This leads to important issues about the ontology of sensory experience, the relationship between cognition and perception. An example of this is ...
