A previously formulated model of deductive reasoning was used as a basis for designing and analyzing a series of four experiments conducted with college student subjects. The formulated problems dealt with both conjunctive and disjunctive concepts and concept instances and with different degrees of concept and instance complexity. Problems generally possessed more than one logically correct solution. Two experiments required subjects to deduce concepts from lists of instances while two other experiments listed concepts from which subjects deduced instances. The pertinence of using deductive techniques is argued for. Modified author abstract
