基于非逻辑机制的条件推理模式:P—Q映射模型及其实证检验

A Conditional Reasoning Model Based on Non-logic Mechanism:P—Q Casting Model

研究结合数学分析方法,提出了基于非逻辑机制的条件推理模型:P—Q映射模型。并根据这个模型,对人们在不同命题类型条件下的推理行为进行了预测。预测结果显示,当推理前提为LH和HL型命题时,基于P—Q映射模型的预测结果与基于条件概率模型的预测结果完全一致。但当推理前提为LL和HH型命题时,两种模型给出的预测结果存在差异。实验结果表明,当前提命题为LL和HH型命题时,被试的条件推理行为与P—Q映射模型的预言完全一致。

A new conditional reasoning model： P--Q casting interrelation model, is presented in the hght of investigation on non- logical conditional reasoning mechanism. For the conditional reasoning related to LH and HE types of proposition, the prediction made by P--Q casting interrelation model is the same as that made by probabilistic computational model. But for the conditional reasoning related to LL and HH types of proposition, the prediction made by P--Q casting interrelation model is opposite to what made by the pmbabihstic computational model. An experiment was designed and performed to find the fitter model between the two models. Experimental results show that subject＇ s reasoning performance is identical with what the P--Q casting interrelation model predicted.
