Abstract

This article analyses the effects of stress on human cognitive processes, including attention, memory, thinking, working memory and information processing. The physiological and neurobiological mechanisms of stress are examined, with particular emphasis on the role of the hypothalamic–pituitary–adrenal axis, cortisol and catecholamines in cognitive functioning. The findings indicate that increasing stress levels are associated with reduced cognitive performance. The study also demonstrates that the duration and intensity of stress exert differential effects on cognitive functions. The results underscore the importance of effective stress management for maintaining and improving cognitive performance.
