Adapting social conditioned place preference for use in young children

Social-emotional processing is key to daily interactions and routines, yet a challenging construct to quantify. Measuring social and emotional processing in young children, children with language impairments, or non-verbal children, presents additional challenges. This study addresses a pressing need for tools to probe internal responses such as feelings, drives, and motivations that do not rely on intact language skills.

In this study, we extend our recent success of inducing conditioned place preference (CPP) in children to demonstrate the success of using a social unconditioned stimulus in the CPP paradigm in both typically developing children (n = 36) and in children with a diagnosis of autism spectrum disorder (n = 14).

This is the first study to demonstrate successful social conditioned place preference in the human population. Both typically developing children and children with autism spectrum disorder demonstrate significant social conditioned place preference by spending significantly more time in the room paired with social interaction following training.

Significant heterogeneity of CPP scores in both groups of children indicates that social motivation is expressed along a continuum, and that the CPP paradigm may provide a more comprehensive characterization of social motivation beyond a diagnosis of an autism spectrum disorder for each child.
