They provide individual, family, and group psychotherapy, and design and implement behavior modification programs. They may collaborate with physicians and other specialists in developing and implementing treatment and intervention programs that patients can understand and comply with. Some clinical psychologists work in universities, where they train graduate students in the delivery of mental health and behavioral medicine services. Others administer community mental health programs. Relatively new specialties within clinical psychology include cognitive psychology, health psychology, neuropsychology, and geropsychology.
Cognitive psychologists deal with memory, thinking, and perceptions.
Some conduct research related to computer programming and artificial intelligence. Health psychologists promote good health through health maintenance counseling programs that are designed to help people achieve goals such as to stop smoking or lose weight. Neuropsychologists study the relation between the brain and behavior. They often work in stroke and head injury programs. Geropsychologists deal with the special problems faced by the elderly.
