Two experiments were performed to investigate the influence of relevance on the performance of Wason selection task In Experiment 1, the effects of negative consequents were observed and the inspecting order of the cards was correlated with the proportion of selection of the cards, which seemed to support relevance based processing of selection tasks. The effects of negative consequents and the content of the conditionals on the performance of Wason selection task were more systematically explored in Experiment 2. The effects of negative consequents and the effects of content seemed to be additive. That is, they work independently of each other, which suggested that the two work in different stages. In addition, effects of perspectives on the performance of Wason selection task were also observed in one of the two problems of Experiment 2.
