Too much human behavior to study
Sometimes people develop theories off of their own perspectives, and communication would be

Communication - A process in which individuals use symbols to establish and interpret
meaning in their environment.
To different people from different environments or with different relationships, communication
may be interpret differently.
The establishment of meaning is very important.
Models of communication: Linear (1949), Interactional (1954), Transactional (1970) history of
