When they interact with each other across group lines, they subconsciously shift their vocabulary and sentence structures to match. This 'linguistic dance' proves that neurodivergent communication isn't broken; it's just happening on a different frequency. It suggests that these groups have a unique, cross-community social fluency that traditional psychology has largely overlooked.

From the abstract

Social media research on mental health has focused predominantly on detecting and diagnosing conditions at the individual level. In this work, we shift attention to \emph{intergroup} behavior, examining how two prominent neurodivergent communities, ADHD and autism, adjust their language when engaging with each other on Reddit. Grounded in Communication Accommodation Theory (CAT), we first establish that each community maintains a distinct linguistic profile as measured by Language Inquiry and Wo
