Cognitive Development
Functioning and Multitasking in Adolescents
Impact of media multitasking on executive function in adolescents: behavioral and self-reported evidence from a one-year longitudinal study
Emerald · 2021-12-15
Summary
Adolescents frequently engage with multiple screens simultaneously, raising concerns about its effects on cognitive abilities like attention and executive functioning.
Key Findings
Reduced Task Performance: Adolescents who multitasked with media performed worse on tasks requiring sustained attention and working memory.
Increased Impulsivity: High media multitaskers exhibited greater impulsivity and difficulty delaying gratification.
No Benefits Observed: Multitasking did not improve adolescents’ ability to switch tasks efficiently.
X-Axis:
Represents Media Multitasking Levels (Low Multitasking, Moderate Multitasking, High Multitasking).
This axis categorizes adolescents based on the degree of simultaneous media usage.
Y-Axis:
Represents Cognitive Performance Scores.
This axis includes scores for Attention and Memory, reflecting cognitive task performance.
Population: 300 adolescents aged 12-17.
Methodology: Participants completed cognitive tests assessing attention, memory, and task-switching while multitasking with media. Surveys captured self-reported media habits.
Implications: Encouraging single-tasking and limiting simultaneous media use can enhance focus and cognitive performance in adolescents.
