Purpose of review: In this review, we embrace the emerging field second-person neuroscience to address disorganization in schizophrenia. We argue that focus interest for is interpersonal space where shared mental processes (‘social mind’) occur based on bio-behavioural synchrony between two (or more) interacting people. lay out several measures can capture component parts process. particular, highlight real-time imaging technology hyperscanning enables multi-person analysis naturalistic social interaction. illustrate how these be used empirical studies by posing as a problem processing. Recent findings: Traditionally, disorganized speech and behaviour have been studied product hidden cognitive (‘private mind’). A dysfunction was attributed brain afflicted illness (‘brain-bound mechanisms’). But approach has contributed challenges measuring quantifying disorganization. Consequently, single-brain not provided satisfactory clarity or led effective treatments persistent schizophrenia.Summary: Social core feature This arises from interaction typifies profile affected individuals. outline employing concepts methods they addressed investigate mechanisms
