study of human mind and behavior? i think it involves emotions, too.
i was thankful to whoever starts the study, because it helps people understand another better? even understand them self better.
studying psychology helps me since i was diagnosed with manic/bipolar syndrome.

how people's mind works and their body language!! Like, why do you think they do this action? There must be a reason for them doing this. blahblahblah.

I am a psychology graduate and this is what I learned from my professors (actually it is pretty simple): psychology is the scientific study of human behavior ;)

Understanding how the human mind works and functions. Psychology helps break down the behavior of humans and their minds

Studying the human mind and how it works
Hope that helps you :)

Um...study of the brain and how people think. Interpreting behavior and body language.
