Sažetak
An increasing number of people, students in particular, seek substances that improve their cognitive functioning. The most popular group of pharmacological cognitive enhancers (PCEs) are stimulants. Available studies suggest a small beneficial effect of methylphenidate and amphetamine on memory, executive functions, and processing speed. However small, this effect can make the difference between success and failure. In recent years, research has focused on the additional beneficial effect on the emotional state, increased motivation, and placebo-induced cognitive enhancement. This paper briefly reviews the latest and most important research on the relationship between popular stimulants and cognitive enhancement. One cannot understand this relationship without understanding the Yerkes-Dodson law, which explains the relationship between the degree of arousal and performance. It suggests that the effect of stimulants is a dose-dependent continuum. This law has repeatedly been confirmed by studies in which an optimal level of psychoactivation for cognitive enhancement was obtained with low stimulant doses, whereas exceeding the effective dose resulted in cognitive deficits, psychomotor agitation, and addiction. A separate section has been devoted to modafinil, an increasingly popular stimulant that differs from the rest in neurochemical profile and behavioural effects.
