Difference b/w psychologist and psychatrist

A psychologist has a doctorate degree in psychology. A psychiatrist has a degree in psychology as well as a medical degree so that the psychiatrist is able to prescribe medication for the psychological condition as well as other therapy.

A psychologist has either a master's degree in psychology or a Ph.d. in psychology or an Ed.d. or a Psy.d. (all of these are doctorate level, with exception to the first one mentioned.) Again, one is a psychologist with certification and a master's degree in psychology or above. A psychiatrist is an m.d., that is physician, and some study in psychology, but not necessarily that much. He/she specializes more in medicine, whereas the psychologist specializes more in behavioral treatments and therapy.

Psychologist deals with the human nature and behaviour, while Psychatrist deals with the state of mind of a person.

One is a doctor other one is a Prescriber

A psychologist cannot prescribe medicine although they can be a 'doctor' by possessing a doctorate degree. A psychiatrist IS a medical doctor (went to med school) and can prescribe medications.
