Doll play improves false belief reasoning: Evidence from a randomized-control trial

Area of Science:

• Developmental Psychology
• Childhood Cognition
• Social-Emotional Learning

Background:

• Play is recognized as a crucial activity for children's cognitive and socio-emotional development.
• Understanding false beliefs is a critical aspect of social cognition, developing in early childhood.

Purpose of the Study:

• To investigate the causal impact of doll play versus creative tablet play on children's false belief understanding.
• To explore the relationship between pre-existing peer problems and the effectiveness of doll play interventions.

Main Methods:

• A randomized control trial involving 73 children aged 4-8 years.
• A six-week play intervention comparing doll play with creative tablet play.
• Assessment of false belief understanding and observation of social play behaviors and language use.

Main Results:

• Doll play significantly improved false belief understanding compared to creative tablet play.
• Improvements were more pronounced in children with higher parent-reported peer problems.
• Children engaged in more social play and used more internal state language with dolls than with tablets.

Conclusions:

• Doll play serves as a valuable tool for enhancing social processing skills, particularly false belief reasoning.
• The findings highlight the potential of doll play to support children with social challenges.
• Further research is needed to elucidate the specific mechanisms through which doll play facilitates social skill development.
