Abstract
Abstract. The increasing use of digital technology among adolescents and young adults has led to concerns about possible detrimental effects on cognitive and brain functions. Indeed, as reviewed here, according to behavioral and brain-imaging studies, excessive media multitasking (i.e., using different digital media in parallel) may lead to enhanced distractibility and problems in maintaining attention. However, frequent video gaming may be beneficial for the development of working memory, task switching, and attention skills. All these cognitive skills depend on executive cognitive functions. Still scant but gradually cumulating brain-imaging results suggest that the negative effects of frequent media multitasking and the positive effects of frequent video gaming on cognitive skills in adolescents and young adults are mediated by effects on the frontal lobes, implicated in executive cognitive functions and still developing even through early adulthood.
