Those who are drawn to understanding the whys and hows of the human mind would do well to study psychology. As opposed to neurobiology which studies the brain, psychology studies the mind, which is human behavior, emotions, perception, motivation, and things like cognition and attention. Human personality, interpersonal relationships and brain functioning are also studied in formal psychology programs.
As with any field, specialization is rampant. Psychologists divide themselves into different theoretical and practical schools, such as applied psychology, which attempts to apply various behavioral and cognitive theories to real world applications. Within applied psychology there is forensic psychology, industrial/occupational or io psychology , and developmental psychology as well as several other subfields.
Some popular subfields or schools of psychological theory and research include clinical psychology, comparative psychology, and biological psychology. There are also behavioralists, Freudians (who practice psychoanalysis) cognitive psychologists, and those that subscribe to theories of functionalism, structuralism, gestalt , or humanism.
Many psychologists end up as either researchers or as therapist. Still others end up in fields that allow them to apply their work to corporate and other organizations, within the criminal justice field, or in helping develop and administer programs for schools, at-risk populations, or other groups such as prisoners or victims.
