Abstract

Two experiments were conducted to explore causal reasoning processes. Wason's selection task was used in both experiments. Arbitrary, regulative, and causal conditionals were used in Experiment I. Results of Experiment 1 showed that causal conditional reasoning is different from other conditional reasoning. Causal conditionals were furthere classified into three types in Experiment 2: Single cause condition, alternative cause condition in which either of two causes can yield the consequent, and additive condition in which two causes were both needed for the consequent. Performance in the alternative condition was almost identical to that of additive condition: Subjects select only one alternative, true consequent. The result of Experiment 2 was interpreted that undifferentiated causal schema was likely to be used in causal reasoning.
