Psychology is the systematic investigation of the human mind, including behavior and cognition. It thus encompasses both normal and abnormal behavior. On the other hand, psychiatry is a branch of medicine dealing with mental illness.
Both psychiatrists and psychologists are typically trained to practice psychotherapy -- talking with their patients about their problems. But the differences in background and training translates into different approaches to solving your mental health problems. Psychologists look closely at your behavior.heyâre not medical doctors. A psychologist can have a PhD in philosophy or a PsyD in clinical or counseling psychology. Typically, they do 1-2 years of internship. Unlike psychiatrists, psychologists are also trained in giving psychological tests (like IQ tests or personality tests).
