Kids as young as 4 to 6 demonstrate proactive response planning in their working memory. Developmental psychologists previously believed this ability only emerged around age 7 when the brain matures more fully. These younger children actually anticipate and prepare for cognitive demands instead of just reacting to them in the moment. This change in understanding means early childhood education should probably focus on strategic thinking much sooner. Preschoolers are far more cognitively sophisticated than the current curriculum assumes.
From the abstract
Proactivity is the capacity to anticipate, and to mentally and behaviorally prepare for, upcoming cognitive demands. Understanding its emergence is key to understanding children’s cognitive functioning and development. In working memory, proactive behavior can take the form of planning response sequences for the recall of to-be-remembered lists. Chevalier et al. (2014) showed its emergence around age 7. However, a high cognitive load may have influenced their results. Therefore, we used a task c
