Pandemic-era Slowdown in Kids’ Executive Function, Study Finds

A Harvard-led longitudinal study of 3,107 children in Massachusetts (2018–2023) found that the COVID-19 pandemic significantly slowed the development of executive function in kids aged 3–11, with growth rates below typical norms across all income levels, suggesting a systemic ‘cognitive stall’ that may underlie ongoing academic and behavioral challenges and requiring targeted, systemic support to rebuild foundational skills.
