• Psychologists study mental processes and human behavior by observing, interpreting, and recording how people and other animals relate to one another and the environment.
  • To do this, psychologists often look for patterns that will help them understand and predict behavior using scientific methods, principles, or procedures to test their ideas. Through such research studies, psychologists have learned much that can help increase understanding between individuals, groups, organizations, institutions, nations, and cultures.
  • Like other social scientists, psychologists formulate theories, or hypotheses, which are possible explanations for what they observe.
  • But unlike other social science disciplines, psychologists often concentrate on individual behavior and, specifically, in the beliefs and feelings that influence a person’s actions.
  • Research methods vary with the topic which they study, but by and large, the chief techniques used are observation, assessment, and experimentation.
  • Psychologists sometimes gather information and evaluate behavior through controlled laboratory experiments, hypnosis, biofeedback, psychoanalysis, or psychotherapy, or by administering personality, performance, aptitude, or intelligence tests.
  • Other methods include interviews, questionnaires, clinical studies, surveys, and observation—looking for cause-and-effect relationships between events and for broad patterns of behavior.
  • Research in psychology seeks to understand and explain thought, emotion, feelings, or behavior.
  • The research findings of psychologists have greatly increased our understanding of why people and animals behave as they do.
  • For example, psychologists have discovered how personality develops and how to promote healthy development. They have gained knowledge of how to diagnose and treat alcoholism and substance abuse, how to help people change bad habits and conduct, and how to help students learn. They understand the conditions that can make workers more productive.

The emergence and growth of these, and other, specialties reflects the increasing participation of psychologists in direct services to special patient populations.
