Working memory is key for developing time-based prospective memory (PM) in children transitioning to school. This study shows working memory, not inhibitory control, significantly impacts PM growth during this crucial developmental period.
Area of Science:
- Cognitive psychology
- Developmental psychology
- Neuroscience
Background:
- Prospective memory (PM) is crucial for daily functioning, involving remembering to perform intended actions.
- Time-based PM, remembering to act at a specific time, undergoes significant development during early childhood.
- Executive functions, including working memory and inhibitory control, are vital for cognitive development and may influence PM skills.
Purpose of the Study:
- To investigate the developmental trajectory of time-based prospective memory (PM) from preschool to early school age.
- To examine the mediating roles of executive functions (working memory, inhibitory control) and time monitoring in the development of time-based PM.
- To identify key cognitive predictors of time-based PM growth during the transition to school.
Main Methods:
- A computer-based driving game was used to assess time-based PM in preschool and primary school children.
- Participants completed an ongoing task (driving) and a PM task (refueling based on a hidden timer).
- Mediation models were applied to analyze the influence of working memory, inhibitory control, and time monitoring on PM performance.
Main Results:
- A significant developmental increase in time-based PM performance was observed between preschool and primary school children.
- Working memory was identified as a significant predictor influencing the development of time-based PM.
- Inhibitory control alone did not significantly mediate the relationship between age and time-based PM.
Conclusions:
- Working memory plays a critical role in the developmental enhancement of time-based prospective memory during the preschool to school-age transition.
- The findings highlight working memory as a primary cognitive driver for improving time-based PM skills in early childhood.
- Further research may explore the interplay of other executive functions and cognitive strategies in time-based PM development.
