Well there's actually a significant amount of overlap between psychiatry and psychology. I think the primary distinction would be more from the training aspect. Psychiatrists have completed medical education; they've done a residency that, often in its first year, includes experience in internal medicine, family practice, or neurology. This kind of training gives psychiatrists a medical perspective to the individual. This would allow them to have an understanding of other medical disorders that might manifest themselves with psychiatric symptoms and it also prepares them to be able to prescribe medications. Psychiatry incorporates a lot of the knowledge that has been developed by the field of psychology. Psychology's been very interested in developing the techniques to understand human behaviour, both normal and abnormal, and it has really made a big contribution to what psychiatry does.
