We still don"t know what all the parts can do! tendencies to take mental shortcuts representative heuristics i saw it on tv so it must be more common intuition v scientific method theory prediction experiment observation. Most direct and conclusive way to test a hypothesis independent variable (manipulated) dependent variable(stays the same) result. Same subject will be given multiple manipulations/conditions across time. Usually multiple subjects, but can be single subject. Much less conclusive than experimental design, but still useful. No manipulation of variables, rather it is the observation of already existing variables.
