The impact of the COVID-19 pandemic on young children's executive function: A longitudinal, population-based study

Area of Science:

• Developmental Psychology
• Child Psychology
• Cognitive Neuroscience

Background:

• Executive function (EF) is crucial for academic success, health, and well-being.
• The COVID-19 pandemic presented unprecedented environmental changes for children.
• Understanding the pandemic's impact on cognitive development is essential.

Purpose of the Study:

• To examine the influence of the COVID-19 pandemic on executive function (EF) skills in children aged 3-11.
• To compare post-pandemic EF development rates with typical developmental trajectories.
• To assess if socioeconomic status moderated the pandemic's impact on EF.

Main Methods:

• Analysis of a large, population-based sample (N = 3,107) of children aged 3-11.
• Longitudinal data collection from 2018 to 2023, encompassing the pre- and post-pandemic periods.
• Comparison of observed EF growth rates with established national norms and prior research.

Main Results:

• Children aged 3-11 exhibited a slower rate of executive function (EF) development post-pandemic (0.5 SD below typical).
• This developmental lag was observed across all socioeconomic groups, indicating a widespread effect.
• The findings suggest a significant impact of the pandemic on children's cognitive growth.

Conclusions:

• The COVID-19 pandemic negatively influenced the development of executive function (EF) in young children.
• This EF developmental disruption may contribute to broader post-pandemic challenges in education and well-being.
• There is a critical need to implement strategies supporting children's executive function development.
