Prospective memory performance across adolescence.

Area of Science:

• Cognitive Psychology
• Developmental Psychology
• Neuroscience

Background:

• Prospective memory (PM) is crucial for daily functioning.
• Understanding age-related changes in PM is vital for cognitive development research.
• Adolescence represents a critical period for cognitive maturation.

Purpose of the Study:

• To investigate age differences in event-based prospective memory (PM) between adolescents and young adults.
• To examine how varying task emphasis (ongoing task vs. PM task) affects PM performance across age groups.
• To explore the role of executive capacity in adolescent cognitive development.

Main Methods:

• A cohort of 341 participants aged 13-22 years completed an ongoing task (OT) with embedded prospective memory (PM) cues.
• Participants were instructed to perform a special response upon encountering specific PM cues (negative words) within the OT.
• Task instructions were manipulated to emphasize either the OT or the PM component.

Main Results:

• A significant main effect of age was observed, with young adults outperforming teenagers in PM.
• Teenagers showed greater improvement in PM performance when the PM task was emphasized compared to young adults.
• This suggests age-related differences in how cognitive resources are allocated.

Conclusions:

• Young adults exhibit more robust event-based prospective memory than adolescents.
• Cognitive development during adolescence involves changes in task prioritization and resource allocation.
• Limited executive capacity may underlie observed age-related differences in prospective memory.
