I'm not a native speaker but "The psychologist Mike Manson phoned me this morning" strikes me as clearly incorrect. A proper name itself has got a definite sense, no additional article is needed. There is an exception - the use of "the" with a person's name to mean "the well-known". My name's James Bond. ~ What, not the James Bond?
