The promise of two-person neuroscience for developmental psychiatry: using interaction-based sociometrics to identify disorders of social interaction

Summary Social interactions are fundamental for human development, and disordered social interactions are pervasive in many psychiatric disorders. Recent advances in ‘two-person neuroscience’ have provided new tools for characterising social interactions. Accordingly, interaction-based ‘sociometrics’ hold great promise for developmental psychology and psychiatry, particularly in the early identification of social disorders. Declaration of interest None.
