Experiment Study Of Deontic Conditional Reasoning

Conditional reasoning is an important form of reasoning in psychology research, researchers in the study of the conditional reasoning gained amount of achievements. Since the past two to three decades, researchers began to pay attention to the study of deontic conditional reasoning. Initially, researchers used deontic conditions in the study of Wason selection task and found that deontic conditions had effect of facilitation in Wason selection task. Since then, many researchers adopted deontic conditions in the study of Wason selection task, results of these researches showed that deontic conditions indeed facilitated performance in Wason selection task. In order to have a comprehensive understanding of deontic conditional reasoning, some researchers held that we should not do deontic conditional reasoning only in Wason selection task. Then, researchers applied practical materials to deontic conditional reasoning.In this paper, the study of deontic conditional reasoning was briefly reviewed. To investigate factors affecting deontci conditional reasoning, promise conditions, threat conditions, propose conditions as well as warning conditions were used in the research. In experiment 1, results showed: (1)The control of speaker who announces a condition affected reasoning. (2)Subjects endorsed more inferences in the high control conditions than in the low control conditions. (3)Condition types and conclusion types also had effects on inference. Subjects endorsed more inferences in the inducement conditions than in the advice conditions. Subjects accepted more MP and DA than AC and MT. In experiment 2, the reason why subjects endorsed more inferences in high control conditions was investigated. The reason is as follows: Credibility of conditions were higher in high control conditions than in low control conditions. Subjects believed that conditional probabilities P (q | p) of high control conditions were higher than the low control conditions'; the causal relationship between antecedent and consequent in high control condition was stronger than low control condition's.
