Communication and Interpersonal Skills
The mechanics
Every message has a sender, a message, a channel, a receiver, feedback and 'noise' (barriers). Barriers include jargon, assumptions, bias, language, hearing loss, emotion and environment. Tone, pace and volume carry more weight than the words chosen, and non-verbal signals - posture, distance, gestures, facial expression - carry more again. Proxemics matters: intimate space, personal space, social space and public space each demand different behaviour, and crowding a person escalates conflict.
Listening and questioning
Active listening means attending, reflecting feeling, paraphrasing, clarifying and summarizing. Use open questions to get a narrative ('Tell me what you saw'), then closed questions to confirm detail ('Was the door locked?'). Avoid leading questions that suggest the answer. Take notes at the time; quote exact words where they matter.
Managing people
De-escalation: slow down, lower volume, use the person's name, keep hands visible, maintain distance and an exit route, offer choices, avoid ultimatums and threatening gestures. Use 'I' statements and assertive (not aggressive) language. Recognize intoxication, mental-health crisis, trauma and cultural difference, and adjust rather than argue. Do not give legal advice, make promises ('the police will arrest him'), or disclose personal information - PIPA limits what you may share and with whom. Radio and telephone traffic should be brief, clear, and use standard phonetics.
Trap: closed questions that produce one-word answers and lose detail; arguing to 'win'; promising outcomes; and attempting to interview a suspect for a confession. Your role is to observe, stabilize and report - not to investigate serious crime.
Rule of thumb: listen twice as much as you speak, ask open questions first, and use closed questions to lock details down.
