AP Psychology

Ever wanted to know why people act the way they do? What about how optical illusions work? What makes someone intelligent? Want to know why people are attracted to each other? How about what milestones kids reach at certain ages? Why do people obey? What about why you're not paying attention to that humming background noise, but you are are now because I mentioned it? (Creepy, right?)

All this is part of psychology - the study of the behavior and mental processes.
