Interpersonal behavior is the behavior and actions that are present in human relationships. The way in which people communicate, and all that this entails, is considered interpersonal behavior.
Interpersonal behavior may include both verbal communication and nonverbal cues, such as body language or facial expressions. Verbal interpersonal behavior consists of joking, relating to one another via the art of storytelling, and taking or following orders. Interpersonal skills are highly desirable in many situations, specifically careers that rely on personal relationships such as the health care industry or sales.
The study of interpersonal behavior is a social science that examines the way people interact with one another.
