Psychology: is the scientific study of behavior, thought, and experience, and how they can be affected by physical, mental, social, and environmental factors. The scientific method: is a way of learning about the world through collecting observations, developing theories to explain them, and using the theories to make predictions: hypothesis: making predictions. Hypothesis: a testable predication about processes that can be observed and measured. You cannot prove it because in the future someone can prove that you are wrong. Falsifiable: the hypothesis is precise enough it can be proven false. Precision is also important because it will allow other researchers to replicate the study. Astrology is different from science because it is not testable and they want you to take their word for it. Pseudoscience: an idea that is presented as science but does not actually utilize basic principles of scientific thinking or procedure: theories: explaning phenomena.
