Psychologists study cognitive, emotional, and social processes and human behavior by observing, interpreting, and recording how people relate to one another and their environments.
Psychology seeks to understand and explain thoughts, emotions, feelings, and behavior. Depending on the topic of study, psychologists use techniques such as observation, assessment, and experimentation to develop theories about the beliefs and feelings that influence a person’s actions.
Psychologists often gather information and evaluate behavior through controlled laboratory experiments, psychoanalysis, or psychotherapy. They also may administer personality, performance, aptitude, or intelligence tests. They look for relationships or patterns of behavior between events, and use this information when testing theories in their research or treating patients.
