Dude...... what? You mean psychologist/psychiatrist right?
And psychology is what neurology spawned from, just neurology deals with physical matter (the brain) rather than everything else as a whole(emotion for example). This is an excerpt from wikipedia:
Also, "neurological" diseases often have "psychiatric" manifestations, such as post-stroke depression, depression and dementia associated with Parkinson's disease, mood and cognitive dysfunctions in Alzheimer's disease and Huntington disease, to name a few. Hence, there is no sharp distinction between neurology and psychiatry on a biological basis – this distinction has mainly practical reasoning and strong historical roots (such as the dominance of Freud's psychoanalytic theory in the first three quarters of the 20th century – which has since then been largely replaced by the focus on neurosciences – aided by the tremendous advances in genetics and neuroimaging.)
Psychology is the science of behaviour, as they to do experiments and clinical lab studies ect.
