How to say "psychology" in Japanese

Choosing the right word
  • 心理しんりJLPT N3approx.Common
    nounCovers 'psychology' in the sense of a person's state of mind or mentality — how someone thinks and feels — rather than the academic subject, as in trying to understand a criminal's psychology.
    私は彼かれの心理しんりが分わからない。↗
    I can't understand his psychology.
  • 心理学しんりがくCommon
    nounThis is the word for psychology as an academic discipline, the science of the mind that one studies at university. Use it when English 'psychology' names the subject itself.
    この本ほんは心理学しんりがくを取り扱とりあつかっている。↗
    This book deals with psychology.

Choose 心理学 when 'psychology' means the academic discipline or field of study, and 心理 when it means a person's state of mind, mentality, or the way someone thinks and feels.
