Children born during the COVID-19 pandemic’s initial lockdown period are exhibiting increased difficulties with concentration, following instructions, and emotional regulation at age four, according to new research published in the medical journal Archives of Disease in Childhood. The study, conducted by researchers at City St George’s, University of London, evaluated 205 children born in England between March 23 and June 23, 2020. This research represents the first large-scale study in England to examine the development of children born during the height of pandemic-related restrictions.
A “Uniquely Disrupted” Early Development
The findings suggest that the social environment experienced by these children during their first year of life significantly influenced their cognitive development. From March 23, 2020, through July 19, 2021, these infants lived through a period of strict government-mandated restrictions. These included the suspension of baby groups and recreational facilities, the mandatory use of masks, social distancing, and limitations on contact with friends, extended family, and peers. Researchers theorize that this “uniquely disrupted” environment deprived children of the varied social stimuli—such as interaction with diverse groups of people and peer play—necessary to bolster specific cognitive skills.
Impact on Executive Function
The study focused on “executive functions,” a set of cognitive skills essential for daily life, including planning, problem-solving, self-control, and the ability to adapt to new situations. Preliminary results indicated that these functions were lower than pre-pandemic levels and lower than what would be expected based on the children’s non-verbal reasoning abilities. Approximately one-third of the children in the sample were assessed as having needs related to executive functions. In practical terms, this means many children in this group struggle to:

- Maintain focus or complete tasks.
- Resist distractions.
- Recall and adhere to instructions.
- Modify their behavior in response to feedback.
Mixed Results in Language and Motor Skills
While executive functions showed a clear downward trend, other developmental areas presented a more complex picture. Language development, for instance, was not uniformly impacted. While the children’s expressive language—their ability to use words to articulate thoughts and feelings—was lower than expected, their receptive language (the ability to understand speech) remained within normal or even higher-than-expected levels. Researchers believe this may be due to parents dedicating more time to direct communication with their children during the lockdown. Furthermore, the study found that motor skills remained consistent with pre-pandemic standards for the children’s age.
Study Limitations and Future Recommendations
The researchers have identified this as an observational study, noting that it does not establish a direct causal link between lockdown measures and the observed developmental delays. They also acknowledged that the study lacked a direct comparison group and that the sample population had a higher-than-average level of education, which could influence the results. Despite these limitations, the authors emphasize the necessity of ongoing monitoring for this generation. They suggest that additional resources and interventions, both within schools and family environments, may be required to support these children as they navigate their formative years. This research aligns with a broader series of international studies published in 2025 and 2026 that have similarly documented a slowdown in the development of executive functions in children following the pandemic.
