Discipline that studies the mind using scientific method. The processes enacted on mental representations (algorithmic level) Several research methods: questio(cid:374)a(cid:396)ies" a(cid:374)d su(cid:396)(cid:448)eys, case studies, scientific method. Deductive reasoning: experimental methods, control of variables, bit more about the form of an experiment. Psychology and the scientific method cont. scientific method: uses an experiment to test a hypothesis. Hypthetical-deductive approach: hypothesis tested deductively, observe how the world works under controlled conditions, see if observations agree or conflict with hypothesis.

Consider the logic of an experiment with a dv x and a treatment (experimental condition of an iv) y: Goal: see if a change in dv x is observed due to presence of y (ex that y causes a change in dv x) Premise: change in dv x was observed in presence of y.
