Capturing the Developmental Changes in Cognitive Control Engagement in Chinese Preschoolers

Area of Science:

• Developmental psychology
• Cognitive neuroscience

Background:

• Children's cognitive control shifts from reactive to proactive strategies during early development.
• Previous research primarily used cross-sectional designs, limiting understanding of this developmental transition.

Purpose of the Study:

• To longitudinally investigate the developmental trajectory from reactive to proactive cognitive control in preschoolers.
• To examine changes in cognitive control over a five-month period in young children.

Main Methods:

• A longitudinal study involving 60 preschoolers (aged 4 and 5).
• Participants completed two cognitive control tasks (AX-Continuous Performance Test, Cued Task-Switching) twice over five months.

Main Results:

• Children demonstrated significant improvements in cognitive control skills across both tasks.
• The observed improvements indicated a predominantly reactive control pattern persisting within the study interval.
• These gains suggest an age-related, gradual development preparing for future proactive control.

Conclusions:

• The study provides longitudinal evidence supporting a gradual developmental shift from reactive to proactive cognitive control in early childhood.
• Findings highlight the ongoing developmental process of cognitive control strategies in preschoolers.
