However, other specialties in psychology are far removed from counseling. Experimental psychologists attempt to understand the fundamental causes of behavior in man and animals and are usually found in a laboratory doing experiments. Industrial and engineering psychologists try to apply psychological principles in industrial organizations, primarily in selecting and placing employees, training personnel, and generally relieving problems associated with any organization of people. Educational and school psychologists apply psychological principles to improve the teaching-learning process. Social psychologists study how people influence each other.
Psychometric psychologists develop various types of tests, including IQ tests and personality tests.
Developmental psychologists study the development of living organisms from the moment of conception until death. Psychobiologists and neuroscientists study the relationship between brain, physiology, and behavior, while neuropsychologists may apply these relationships to patients in a clinical setting. So psychology is a very broad field that includes many different subfields of specialization. The American Psychological Association , the professional organization of psychologists, lists 50 individual subdivisions of psychology. The goal of all these psychologists is to advance or to apply the scientific understanding of behavior.
