Recent research conducted by psychologists at Cardiff University and King’s College London highlights the developmental benefits of traditional doll play for children aged four to eight, revealing a stark contrast to the effects of digital device usage. The findings suggest that engaging with dolls fosters not only imagination but also critical social skills, which are essential for healthy childhood development.
The Impact of Doll Play on Development
The study, published in the peer-reviewed journal *Plos One*, involved a randomised control trial with 73 children, split into two groups: one playing with dolls and the other using tablets equipped with video games. Over a six-week period, observers noted significant differences in behaviour between the two groups. Children who played with dolls exhibited enhanced abilities to understand others’ beliefs and emotions, a skill known as “false-belief reasoning.” This development allows them to grasp that others may hold different perspectives or knowledge about a situation.
Lead researcher Dr Sarah Gerson, a psychology reader at Cardiff University, explained that doll play provides opportunities for children to engage in role-playing and narrative creation, which are vital for developing social cognition. “These pretend play scenarios enable children to practice social skills and emotional regulation in a safe environment,” she noted. The results indicate that children with dolls were more likely to engage in cooperative play with peers, contrasting sharply with those absorbed in tablet games, who tended to play alone.
Findings on Social Interaction
Parents involved in the study reported that children using tablets were less likely to engage with family members or friends during playtime. This solitary play is concerning, especially in light of increasing screen time among young children, with recent reports showing that infants as young as nine months old in England are averaging 41 minutes of screen exposure daily.

The researchers were particularly encouraged by the substantial increase in false-belief reasoning capabilities among children who played with dolls. These improvements suggest that such play not only enhances imagination but also deepens children’s understanding of social dynamics. “Identifying innovative methods to boost social skills can have lasting implications, as these foundational abilities play a critical role in forming relationships later in life,” Gerson added.
Doll Play vs. Digital Devices
The study’s findings come at a time of growing concern regarding the impact of digital devices on child development. As children increasingly turn to screens for entertainment, the traditional forms of play that foster creativity and interpersonal skills may be sidelined. The research underscores the importance of providing diverse play options that include tangible toys, like dolls, which can promote more interactive and socially enriching experiences.
Notably, the study found no significant difference in the benefits of doll play between boys and girls, suggesting that the advantages of such play are universal across genders. This raises important questions about the types of toys we encourage children to engage with during their formative years.
Scientific Integrity and Funding
It is worth mentioning that the research received funding from Mattel, the American toy company responsible for the Ken and Barbie dolls used in the study. Cardiff University assured that the scientific integrity of the research was maintained, with the data collection and analysis conducted independently. The variety of dolls provided included diverse representations, enabling children to engage in imaginative play without predefined narratives.

Why it Matters
This study sheds light on the critical role that traditional play, particularly with dolls, plays in developing essential social skills and cognitive abilities in children. As discussions about screen time and its adverse effects continue to gain traction, these findings advocate for a balanced approach to play. Encouraging children to engage in imaginative play with dolls could be instrumental in nurturing their social capacities, ultimately shaping healthier relationships and emotional intelligence as they grow.
