Background: A person's ability to solve several tasks simultaneously, or within a limited amount of time, - , multitasking - is becoming more and more highly valued in society, despite experimental data in cognitive science about the low effectiveness of such activity. But, in the modern world, the term multitasking has become increasingly used in another sense - that is, a personal choice to perform several tasks simultaneously even if a person could do them consecutively.
Objective: The aim of this study was to reveal the relationship between a personal preference for multitasking, its subjective effectiveness in children and adolescents, and their tendency for and efficacy of multitasking under experimental conditions.
