Interpersonal communication is defined by communication scholars in numerous ways, though most definitions involve participants who are interdependent on one another, have a shared history. It can be categorized into two main categories: Direct and Indirect channels of communication.
Channels means mode of communicating the messages.
Direct channels are those that are obvious and can be easily recognized by the receiver. In this category are the verbal and non-verbal channels of communication. Verbal communication channels are those that use words in some manner, such as written communication or spoken communication. Non-verbal communication channels are those that do not require words, such as certain facial expressions, controllable body movements, colour, sound etc.
Indirect channels are those channels that are usually recognized subliminally or subconsciously by the receiver, and not under direct control of the sender. This includes kinesics or body language, which reflects the inner emotions and motivations rather than the actual delivered message.
Participants are the communicators who are both senders and receivers.
Fundamental Interpersonal Relations Orientation (FIRO) is a theory of interpersonal relations, introduced by William Shultz in 1958.

Shultz believed that FIRO scores in themselves were not terminal, and can and do change, and did not encourage typology.
Inclusion means that how a person who want to participate or to join a group of people. In wanting inclusion, he or she hopping that someone would call them to join the team. This means that they have a desire wanting other people to call for them. But in expressing inclusion, they will walk to a team offer to join the team.
Control means that mostly have something to do with respect to control and power. It has to do with being on top or on the bottom. In expressing control, they tend to be a leader that try to control and order people to follow their order/s. In wanting control, they will always have “you decide, I’ll follow” in their mind.
Affection means that either receives or gives the distribution of love and care to someone or from someone. In wanting affection, they have needs to feel warm and like people to be close to them. In expressing affection, they tend to be close and personalize with other people. They will try to take care and give support to others.
