What kind of processes do you think are involved: memory, perception, logic, reasoning. Types of reasoning: deductive and inductive reasoning, deductive: take several props to come to a conclusion, have premises and conclusion. Propositional logic: inductive: conclusion does not have to follow from premises, categorical syllogism: all something are something, x is a something, x must be something. Have quantifiers: validity is form, truth is content, not the same, conditional syllogism: if then, affirming the antecedent and denying the consequence. Must falsify principle to test if correct: people better if problems relate to real life, pragmatic reasoning schemas: schemas from real life, like permission, help us to solve problem idea, detecting cheating processes as the way that we solve.
