Intrapersonal communication is communication with oneself using internal vocalization or reflective thinking. Like other forms of communication, intrapersonal communication is triggered by some internal or external stimulus. We may, for example, communicate with our self about what we want to eat due to the internal stimulus of hunger, or we may react intrapersonally to an event we witness. Unlike other forms of communication, intrapersonal communication takes place only inside our heads. The other forms of communication must be perceived by someone else to count as communication. So what is the point of intrapersonal communication if no one else even sees it?

Intrapersonal communication is communication with ourselves that takes place in our heads.

Intrapersonal communication serves several social functions. Internal vocalization, or talking to ourselves, can help us achieve or maintain social adjustment.^[1] For example, a person may use self-talk to calm himself down in a stressful situation, or a shy person may remind herself to smile during a social event. Intrapersonal communication also helps build and maintain our self-concept. We form an understanding of who we are based on how other people communicate with us and how we process that communication intrapersonally. The shy person in the earlier example probably internalized shyness as a part of her self-concept because other people associated her communication behaviors with shyness and may have even labeled her “shy” before she had a firm grasp on what that meant. We also use intrapersonal communication or “self-talk” to let off steam, process emotions, think through something, or rehearse what we plan to say or do in the future. As with the other forms of communication, competent intrapersonal communication helps facilitate social interaction and can enhance our well-being. Conversely, the breakdown in the ability of a person to intrapersonally communicate is associated with mental illness.^[2]

Sometimes we intrapersonally communicate for the fun of it. I’m sure we have all had the experience of laughing aloud because we thought of something funny. We also communicate intrapersonally to pass time. I bet there is a lot of intrapersonal communication going on in waiting rooms all over the world right now. In both of these cases, intrapersonal communication is usually unplanned and doesn’t include a clearly defined goal.^[3] We can, however, engage in more intentional intrapersonal communication. In fact, deliberate self-reflection can help us become more competent communicators as we become more mindful of our own behaviors. For example, your internal voice may praise or scold you based on a thought or action.

Of the forms of communication, intrapersonal communication has received the least amount of formal study. It is rare to find courses devoted to the topic, and it is generally separated from the remaining four types of communication. The main distinction is that intrapersonal communication is not created with the intention that another person will perceive it. In all the other levels, the fact that the communicator anticipates consumption of their message is very important.
