Which of the following are true in the case of metacommunication?

Metacommunication is not always intentional, often takes place spontaneously and can modify itself, so statements 2, 3 and 4 hold true.

Statement 2 is right because the signals about how a message should be taken frequently slip out beyond the sender's deliberate control.

Statement 3 is right because such cues, tone, expression and posture, arise spontaneously alongside the main message.

Statement 4 is right because metacommunication can adjust and reframe itself as the exchange unfolds.

Saying it is intentional in statement 1 is too narrow, since much of it is unplanned and unconscious.

Saying it decontextualizes itself in statement 5 is wrong, because metacommunication is deeply bound to and dependent on its context.

Bateson introduced metacommunication as communication about communication, the frame that tells us how to read a message.
