Non-verbal communication skills in relationships can be explicitly taught rather than solely acquired

The claim states that non-verbal communication skills in relationships can be explicitly taught rather than solely acquired. While the provided papers do not specifically isolate non-verbal communication training in a controlled experiment, multiple qualitative and needs-assessment studies in the literature emphasize that relationship skills, interpersonal communication, and emotional regulation can and should be actively taught via educational interventions, supporting the broader premise that relationship skills are learnable rather than purely innate.
