HAULT

Cognitive inhibition refers to the mind's ability to tune out stimuli that are irrelevant to the task/process at hand or to the mind's current state. Cognitive inhibition can be done either in whole or in part, intentionally or otherwise.[1] Cognitive inhibition in particular can be observed in many instances throughout specific areas of cognitive science

 Cognitive inhibition, of course, is responsible for determining what is relevant to the working memory and shuts out what is irrelevant, "freeing up space" and mental capacity needed for more pressing matters. In the theory of inefficient inhibition, cognitive inhibition does not perform its function fully, and a shortage of mental resources leads to decreased performance or inefficiency in tasks that require more mental capacity. While inefficient inhibition can result naturally in individuals diagnosed with mild cognitive impairment, this effect is especially pronounced in methamphetamine-dependent individuals.[10] Clinically, these individuals can be highly distractible and exhibit difficulty focusing, which illustrates the fact that cognitive inhibition is being impaired and that inefficient inhibition is resulting. Because of the nature of thepsychoactive drug, the brain is unable or reduced in its capacity to shut out irrelevant stimuli to the task at hand, and so tries to process and respond to any and all stimuli.
