Insights
The Active Early Learning (AEL) program improved preschool children's executive function and expressive vocabulary. This childcare-based physical activity intervention showed positive effects on inhibition and language development.
Area of Science:
- Child Development
- Pediatric Health
- Educational Psychology
Background:
- Executive function and expressive vocabulary are crucial for early childhood development.
- Childcare settings offer opportunities for structured physical activity interventions.
- Previous research indicates a link between physical activity and cognitive development in children.
Purpose of the Study:
- To evaluate the impact of the Active Early Learning (AEL) intervention on executive function and expressive vocabulary in preschool children.
- To determine if a center-based physical activity program integrated into childcare routines can enhance cognitive and language skills.
- To investigate the effectiveness of AEL using a randomized controlled trial design.
Main Methods:
- A randomized controlled trial involving 314 preschool children aged 3-5 years from 15 Australian childcare centers.
- Children were randomly assigned to either the AEL intervention group (n=170) or a control group (n=144).
- Intervention involved integrating AEL physical activity into the daily childcare routine.
Main Results:
- The AEL intervention demonstrated a significant positive effect on children's inhibition, a key component of executive function (β=0.5, p=.033, d=0.29).
- Significant improvements were observed in expressive vocabulary among children in the AEL group (β=1.97, p=.001, d=0.24).
- The intervention was effective in enhancing both executive function and expressive language development.
Conclusions:
- Integrating the Active Early Learning physical activity intervention into daily childcare routines effectively enhances early childhood executive function and expressive language.
- The AEL program provides a viable model for promoting cognitive and linguistic development in preschool settings.
- Findings support the use of structured physical activity programs in childcare to foster holistic child development.
Abstract:
This study aimed to determine the effects of the Active Early Learning (AEL) childcare center-based physical activity intervention on early childhood executive function and expressive vocabulary via a randomized controlled trial. Three-hundred-and-fourteen preschool children (134 girls) aged 3-5 years from 15 childcare centers were randomly assigned to the intervention (8 centers; n = 170 children) or control group (7 centers, n = 144 children) in May 2019. Participants were mostly Australian (85%) and from slightly higher areas of socio-economic status than the Australian average. There was an AEL intervention effect on inhibition (β = 0.5, p = .033, d = 0.29) and expressive vocabulary (β = 1.97, p = .001, d = 0.24). Integration of the AEL physical activity intervention into the daily childcare routine was effective in enhancing children's executive function and expressive language development.
