A psychologist is...

• A. A medical doctor
• B. An expert or specialist in psychology.
• C. A social worker
• D. A nurse

Answer: (B)

A psychologist is an expert or specialist in psychology. They are trained to study behavior and mental processes, often holding advanced degrees in psychology, and they use assessments and therapy to understand and improve how people think, feel, and behave. This role centers on mental health and behavioral science, rather than on medical treatment. Medical doctors diagnose physical illnesses and manage medical interventions, while social workers focus on connecting people to community resources and addressing social factors, and nurses provide hands-on medical care. So the description that best fits is someone who specializes in psychology.
