How can our understanding of perception helps us become more effective communicators?

Yes because perception will help us to become an effective communicator through evaluating all messages from all perspectives like the method communication used and from whom the message came from. It allows as view messages from the source or the situation individually.

When you interacted with someone from a different culture. How did your conversation evolve, using the communication model? What could you have done differently?

When interacting to someone with culture differences using the communication model SMCR or Sender - Message - Channel - Receiver, You as the Sender of the message must be aware on the culture of the one you are talking to. Many cultures expect a degree of formality at the beginning of communication between individuals. Speak slowly and avoid slang for you to deliver the Message correctly and modulating your pace will help, as will speaking clearly and pronouncing your words properly to avoid miscommunication or at worst, offending them. Either you talk to a person personally or over the phone, speaking politely and clearly will definitely be the easiest way to communicate to other with different culture without getting miscommunication.
