The COVID-19 pandemic and subsequent lockdowns have dramatically changed the daily lives of children and families. Schools and daycare centres closed, work and education moved home, and social interactions were restricted. A recent study by Rose Scott and colleagues, published in Scientific Reports, investigated whether these changes affected the development of social cognitive skills in young children, specifically false-belief understanding. This ability to understand that others may hold incorrect ideas or beliefs is crucial for social interaction, communication, and learning.

The study compared the performance of two groups of children aged 3.5 to 5.5 years: one group was tested before the pandemic, and the other group after. Results showed that children tested after the pandemic performed significantly worse on tasks measuring false-belief understanding than children tested before. This difference was greater for children from lower socioeconomic status (SES) families. The researchers controlled for age and language skills, suggesting that the pandemic has had a negative impact on the development of these important social cognitive skills, especially in children from disadvantaged backgrounds.

The findings are consistent with previous research showing that the pandemic has had negative consequences for various aspects of children’s development, such as mental health, emotional well-being and academic performance. This study extends these findings to early childhood and highlights the importance of social interactions for developing social cognitive skills. During the lockdowns, children had fewer opportunities to interact with peers, which may have contributed to the observed decline.

The study also highlights the greater impact of the pandemic on children from lower SES families, suggesting an increase in socioeconomic inequality in children’s development. The researchers call for additional support for children’s social cognitive development, especially for those from disadvantaged backgrounds, to prevent this inequality from increasing further.

Although the study has some limitations, such as the lack of detailed information on families’ daily interactions during the lockdowns, it provides valuable insights into the long-term effects of the pandemic on young children’s development. It highlights the importance of social interactions and the need for targeted interventions to help children catch up on developmental delays.

Abstract of the study:

The COVID-19 pandemic and ensuing lockdowns led to sweeping changes in the everyday lives of children and families, including school closures, remote work and learning, and social distancing. To date no study has examined whether these profound changes in young children’s day to day social interactions impacted the development of social cognition skills in early childhood. To address this question, we compared the performance of two cohorts of 3.5- to 5.5-year-old children tested before and after the COVID-19 lockdowns on several measures of false-belief understanding, a critical social cognition skill that undergoes important developments in this age range. Controlling for age and language skills, children tested after the pandemic demonstrated significantly worse false-belief understanding than those tested before the pandemic, and this difference was larger for children from lower socioeconomic status (SES) backgrounds. These results suggest that the pandemic negatively impacted the development of social cognition skills in early childhood, especially for lower SES children.
