The second person in 'l'-'you'-'it' triadic interactions

摘要

Second person social cognition cannot be restricted to dyadic interactions between two persons (the "I" and the "you"). Many instances of social communication are triadic, and involve a third person (the "him/her/it"), which is the object of the interaction. We discuss neuropsychological and brain imaging data showing that triadic interactions involve dedicated brain networks distinct from those of dyadic interactions.
