Summary
This review paper examines the cognitive, psychological, neural, and academic consequences of media multitasking (MMT), defined as juggling multiple media streams simultaneously. The study is motivated by the ubiquity of MMT among youth, who spend an average of 7.5 hours daily with media, 29% of which involves multitasking. Because many MMTs are children and young adults with developing brains, the authors aim to characterize the neurocognitive profiles of heavy media multitaskers (HMMs) versus lighter media multitaskers (LMMs) and assess the impact of MMT on learning. The authors synthesized existing literature to distinguish between the inherent profiles of individuals who engage in varying levels of MMT and the immediate consequences of multitasking during learning tasks. The review covers cognitive domains such as working memory, attention, and inhibitory control; psychosocial traits including impulsivity and anxiety; neural structures identified through neuroimaging; and academic outcomes like grade point average (GPA) and homework performance. Findings indicate that HMMs generally exhibit poorer performance in cognitive domains compared to LMMs, specifically in working memory, interference management, sustained attention, relational reasoning, and inhibitory control. Psychosocially, HMMs show higher trait impulsivity, sensation-seeking, social anxiety, depression, and neuroticism. Neural studies reveal that HMMs have reduced gray matter volume in the anterior cingulate cortex and greater distraction-related activity in prefrontal regions during tasks. Regarding learning, concurrent MMT disrupts academic performance; for instance, reading while instant messaging significantly reduces efficiency and comprehension, and background television impairs homework accuracy and play quality in young children. These behaviors are negatively associated with GPA. The authors conclude that while the direction of causality remains unclear—whether MMT causes these deficits or if individuals with such traits are predisposed to multitask—the evidence suggests MMT negatively impacts concurrent learning and is associated with distinct neurocognitive profiles. They recommend that clinicians and educators advise caution regarding media engagement during learning tasks. Future research must determine causality, identify sensitive developmental periods, and explore effective interventions to mitigate potential harms.
