Educational Psychologists concentrate on how effective teaching and learning take place. They consider a variety of factors, such as human abilities, student motivation, and the effect on the classroom on the diversity of race, ethnicity, and culture. Engineering Psychologists conduct research on how people work best with machines. Most engineering psychologists work in industry, but some are employed by the government, particularly the Department of Defense. They are often known as human-factors specialists.
Forensic Psychologists apply psychological principles to legal issues.
Their expertise is often essential in court. They can, for example, help a judge decide which parent should have custody of a child or evaluate a defendant's mental competence to stand trial. Some forensic psychologists are trained in both psychology and the law. Health Psychologists are interested in how biological, psychological, and social factors affect health and illness. Many serve as human resources specialists, helping organizations with staffing, training, and employee development and management in such areas as strategic planning, quality management, and coping with organizational change.
