Psychology is a rich and diverse field, and a psychology major can prepare students for a variety of future careers, as described by the American Psychological Association. There are many different areas of psychology, including biological psychology, clinical psychology, cognitive psychology, comparative psychology, developmental psychology, educational psychology, industrial psychology, personality psychology, professional psychology, positive psychology, and social psychology. Education requirements for these fields will vary, as will their potential salaries.

What do Psychologists Actually Do?

Psychologists typically do the following: (Direct excerpt from Occupational Outlook Handbook)

• Conduct scientific studies of behavior and brain function
• Collect information through observations, interviews, surveys, and other methods
• Identify psychological, emotional, behavioral, or organizational issues and diagnose disorders, using information obtained from their research
• Research and identify behavioral or emotional patterns
• Test for patterns that will help them better understand and predict behavior
• Discuss the treatment of problems with their clients
• Write articles, research papers, and reports to share findings and educate others

Psychologists seek to understand and explain thoughts, emotions, feelings, and behavior. Psychologists use techniques such as observation, assessment, and experimentation to develop theories about the beliefs and feelings that influence a person.

Psychologists often gather information and evaluate behavior through controlled laboratory experiments, psychoanalysis, or psychotherapy. They also may administer personality, performance, aptitude, or intelligence tests. They look for patterns of behavior or relationships between events, and use this information when testing theories in their research or treating patients.

Types of psychologists

Clinical psychologists assess, diagnose, and treat mental, emotional, and behavioral disorders. Clinical psychologists help people deal with problems ranging from short-term personal issues to severe, chronic conditions.

Clinical psychologists are trained to use a variety of approaches to help individuals. Although strategies generally differ by specialty, clinical psychologists often interview patients, give diagnostic tests, and provide individual, family, or group psychotherapy. They also design behavior modification programs and help patients implement their particular program.

Some clinical psychologists focus on certain populations, such as children or the elderly, or certain specialties, such as the following:

• Health psychologists study how psychological and behavioral factors interact with health and illness. They educate both patients and medical staff on psychological issues and promote healthy-living strategies. They also investigate and develop programs to address common health-related behaviors, such as smoking, poor diet, and sedentary behavior.
• Neuropsychologists study the effects of brain injuries, brain disease, developmental disorders, or mental health conditions on behavior and thinking. They test patients affected by known or suspected brain conditions to determine impacts on thinking and to direct patients’ treatment.

Clinical psychologists often consult with other health professionals regarding the best treatment for patients, especially treatment that includes medication. Currently, Illinois, Louisiana, and New Mexico allow clinical psychologists to prescribe medication to patients. Most states, however, do not allow psychologists to prescribe medication for treatment.

Counseling psychologists help patients deal with and understand problems, including issues at home, at the workplace, or in their community. Through counseling, they work with patients to identify their strengths or resources they can use to manage problems. For information on other counseling occupations, see the profiles on mental health counselors and marriage and family therapists, substance abuse and behavioral disorder counselors, and social workers.

Developmental psychologists study the psychological progress and development that take place throughout life. Many developmental psychologists focus on children and adolescents, but they also may study aging and problems facing older adults.

Forensic psychologists use psychological principles in the legal and criminal justice system to help judges, attorneys, and other legal specialists understand the psychological aspects of a particular case. They often testify in court as expert witnesses. They typically specialize in family, civil, or criminal case work.

Industrial-organizational psychologists apply psychology to the workplace by using psychological principles and research methods to solve problems and improve the quality of work life. They study issues such as workplace productivity, management or employee working styles, and employee morale. They also work with management on matters such as policy planning, employee screening or training, and organizational development.

School psychologists apply psychological principles and techniques to education and developmental disorders. They may address student learning and behavioral problems; design and implement performance plans, and evaluate performances; and counsel students and families. They also may consult with other school-based professionals to suggest improvements to teaching, learning, and administrative strategies.

Social psychologists study how people’s mindsets and behavior are shaped by social interactions. They examine both individual and group interactions and may investigate ways to improve interactions.
