Hyperfocus is an intense form of mental concentration or visualization that focuses consciousness on a subject, topic, or task. In some individuals, various subjects or topics may also include daydreams, concepts, fiction, the imagination, and other objects of the mind. Hyperfocus on a certain subject can cause side-tracking away from assigned or important tasks.
Psychiatrically, it is considered to be a trait of ADHD together with inattention, and it has been proposed as a trait of other conditions, such as schizophrenia, and autism spectrum disorder (ASD).[1][2]
One proposed factor in hyperfocus as a symptom involves the psychological theory of brain lateralization, wherein one hemisphere of the brain specializes in some neural functions and cognitive processes over others. Those who have a tendency to hyperfocus, such as those with ADHD, may experience a form of "pseudoneglect" where attention is dominant on one side of the brain, leading to preferential attention in some neural connections and processes over others overall.[3][4] While this idea is under study, it is not yet empirically proven.[5][6][7]
Hyperfocus may bear a relationship to the concept of flow.[2] In some circumstances, both flow and hyperfocus can be an aid to achievement, but in other circumstances, the same focus and behavior could be a liability, distracting from the task at hand. However, unlike hyperfocus, "flow" is often described in more positive terms, suggesting they are not two sides of the same condition under contrasting circumstance or intellect.[7]
…there are no empirical data that support hyperfocus as an aspect of ADD/ADHD. In gifted children without ADD/ADHD, this rapt and productive attention state is described by Csikszentmihalyi (1990) as 'flow.' … What has been coined 'hyperfocus' in persons with ADD/ADHD seems to be a less medical-sounding description of perseveration. Thus the apparent ability to concentrate in certain limited situations does not exclude the diagnosis of ADD/ADHD.
