The Cognitive Costs of Multitasking: A Critical Examination of Its Impacts on Learning, Brain Structure, and Long-Term Cognitive Function

Abstract

This study explores the cognitive costs of multitasking, focusing on its effects on learning, brain structure, and long-term cognitive function. Through an archival research approach, existing literature was synthesized to examine both the immediate and lasting impacts of multitasking. While previous studies have documented its negative effects on cognitive performance, this research makes a unique contribution by providing practical, easily implementable strategies to counter these detriments. The findings show that multitasking significantly reduces attention span and working memory while also causing structural changes in brain regions associated with cognitive control. However, by offering pragmatic solutions, such as monotasking techniques and strategies for maintaining focus, this study addresses a critical gap in the literature. These actionable recommendations are designed to be directly applicable in educational and professional settings, enhancing cognitive efficiency and improving learning outcomes.
