Focus enhancement is defined as the experience of an increased ability to selectively concentrate on an aspect of the environment while ignoring other things. It can be best characterized by feelings of intense concentration which can allow one to continuously focus on and perform tasks which would otherwise be considered too monotonous, boring, or dull to not get distracted from.
The degree of focus induced by this effect can be much stronger than what a person is capable of sober. It can allow for hours of effortless, single-minded, and continuous focus on a particular activity to the exclusion of all other considerations such as eating and attending to bodily functions. However, although focus enhancement can improve a person’s ability to engage in tasks and use time effectively, it is worth noting that it can also cause a person to focus intensely and spend excess time on unimportant activities.
Focus enhancement is often accompanied by other coinciding effects such as motivation enhancement, thought acceleration, and stimulation. It is most commonly induced under the influence of moderate dosages of stimulant and nootropic compounds such as amphetamine, methylphenidate, modafinil, and caffeine. However, it is worth noting that the same compounds which induce this mind state at moderate dosages will also often result in the opposite effect of focus suppression at heavier dosages.
