Hi there ~
You have your spelling wrong both times in the content of your questions. Assuming that you want to know what the difference between a psychiatrist
and a psychologist
is, I will let you know that psychiatrists go through medical school and complete training in psychiatry to be able to prescribe psychotropic medications. While there are many ways that one could become a psychologist (most of the times not being able to prescribe medications) the doctoral psychologist is considered or repute and a masters level a step below and so on and so forth. However the skill level depends on the experience with patients, either for psychiatrist or a psychologist.
I hope this answered your question. Take care and have a nice day !
