The Pandemic's Hidden Toll: Reception-Year Children Still Lagging on Self-Control

The children who started reception class in September 2020 did not really start school at all. Within weeks, classrooms closed. The routines, the peer learning, the daily social negotiation that normally happens at age four and five - gone almost immediately. A study published in Child Development now quantifies what that loss cost them, in cognitive terms, years later.

A dataset that happened by accident

The research has an unusual advantage: the team at the University of East Anglia was already running a long-term child development study when COVID hit. They had baseline data on children's cognitive abilities before the pandemic began - something almost no other researchers could claim. That pre-pandemic baseline is what makes the findings more than speculation.

In total, 139 children aged between two-and-a-half and six-and-a-half participated, including 94 families who had joined before March 2020. Using the Minnesota Executive Function Scale at regular intervals, researchers tracked self-regulation, cognitive flexibility, and impulse control - the cluster of mental skills collectively called executive functions - across multiple years.

The study compared two groups. One group was in preschool when the first lockdowns hit. The other was in reception - the first year of formal schooling in England. Same pandemic, very different developmental outcomes.

Reception year proved to be the critical window

"Children who were in reception when the country shut down showed much slower growth in key self-regulation and cognitive flexibility skills over the next few years than children who were still in preschool," said lead researcher Professor John Spencer from UEA's School of Psychology.

Reception-age children found it harder to shift between tasks and suppress impulses - abilities that normally accelerate once children enter structured classroom environments. The gap between the two groups persisted even years after schools reopened.

Why reception and not preschool? Spencer's explanation centers on what reception actually does developmentally. It is when children absorb classroom norms, form their first peer relationships, and begin practicing the kind of behavioral flexibility that adult life will eventually demand constantly. Preschool-age children are still mostly in parallel play; reception-age children are learning to cooperate, take turns, follow a teacher's instructions, and manage their emotions in a social setting. Strip all of that out for a year and the developmental consequences are measurable.

Other patterns in the data

Several findings in the study are consistent with what earlier research has suggested. Executive function abilities were remarkably stable individually: children who scored higher at age two-and-a-half tended to remain ahead at six-and-a-half, regardless of the pandemic's disruption. Children from lower socioeconomic households scored consistently lower across all time points - a pattern that echoes decades of research on the role of maternal education and home environment in early cognitive development.

Notably, the pandemic's effect persisted even after controlling for age and family background, indicating it was not simply a proxy for pre-existing inequality. Children in reception at the start of lockdowns made more modest improvements in executive function compared to their preschool-age counterparts, net of other factors. Many of those children also caught COVID more frequently during the pandemic period, raising the possibility that illness itself compounded the developmental disruption.

What comes next for these children

The researchers are careful not to predict permanent deficits. Executive function continues to develop well into adolescence, and targeted interventions can accelerate growth. But the study's findings suggest this cohort may need more support from teachers, schools, and health services in the years ahead than previous generations required at the same ages.

The findings also carry a forward-looking message about how to protect children's development during future crises. If reception year is a critical window, then decisions about school closures need to weigh the cognitive cost to children at that specific developmental stage - not just the general disruption of lost school days.

The research was a collaboration between the University of East Anglia, Lancaster University, and Durham University.
