Think about the environment
Communication doesn't happen in isolation.
Noise, busy rooms, several people talking at once, unfamiliar people, poor lighting or other distractions can make communication more difficult.
Think about the person's individual needs.
Would it help to:
- Turn down background noise?
- Have one person speaking at a time?
- Move somewhere quieter?
- Reduce distractions?
- Make what is going to happen more predictable?
Sometimes improving communication means changing the environment rather than changing the person.
