Psychology is the scientific study of mental processes and behavior.
Psychologists observe and record how people and other animals relate to one another and to the environment. They look for patterns that will help them understand and predict behavior, and they use scientific methods to test their ideas. Through such studies, psychologists have learned much that can help people fulfill their potential as human beings and increase understanding between individuals, groups, nations, and cultures. Psychology is a broad field that explores a variety of questions about thoughts, feelings, and actions. The research findings of psychologists have greatly increased our understanding of why people behave as they do.
