Psychologist
A psychologist is a professional who evaluates and studies behavior and mental processes (see also psychology). Typically, psychologists must have completed a university degree in psychology, which is a master's degree in some countries and a doctorate in others (e.g., United States, Canada and United Kingdom). This definition of psychologist is non-exclusive; in most jurisdictions, members of other professions (such as counselors and psychiatrists) can also evaluate, diagnose, treat, and study mental processes. Some psychologists, such as clinical and counseling psychologists, provide mental health care, and some psychologists, such as social or organizational psychologists conduct research and provide consultation services.
Clinical, counseling, and school psychologists who work with patients in a variety of therapeutic contexts (contrast with psychiatrists, who are physician specialists).
Industrial/organizational and community psychologists who apply psychological research, theories and techniques to "real-world" problems, questions and issues in business, industry, social benefit organizations, and government.
