Michael Argyle, who was a social psychologist, in 1972. The concept of a ‘communication cycle’ makes it clear that, in order to have effective communication, it must be a two way process. As well as transferring messages to others in a definite, clear way, health care professionals must be able to respond to the verbal feedback as well as the non-verbal feedback. So, effective communication has to involve effort from both participators (both the sender as well as the receiver) in the communication.
