An experiments consisting of 3 factors (propositions (14 kinds), the number of attributes (2 or 3 attributes) and tasks (selection and truth table)) were conducted in order to develop the psychological problems in Wason's selection tasks structurally. Out of the 16 two-term propositions, 14 propositions were used as rules in the questions. These propositions consisted of 4 conjunctives, 1 disjunctive, 3 conditionals, 2 biconditionals, and 4 one-terms. 36 students served as Ss, and each was given 56 questions according to the design of the experiments. The main results were as follows: (1) with respect to the prepositional factors, the conditional and biconditional ones were more difficult than others; (2) the factor of the number of attributes influenced only the conjunctive questions. It was concluded that analysis of data on complex conditions concerning the Wason' s selection was possible as long as a framework of comprehensive structural features of the tasks was understood clearly and accurately.
