The results showed:(1)the factors which influence causal judgment were that the cause was the real cause or stimulative,the familiarity of the cause,and the covariation degree of causes with outcomes;(2)the character of questions didn't influence causal judgment;(3)causal judgment...

结果发现：(1)影响因果判断的因素有：事件原因与促进条件的性质差异，原因的熟悉度，原因和结果的共变程度；(2)问题抽象性对因果判断没有影响；(3)概率对照模型和因果模型理论在一定的情况下适用，但是都不能解释所有的情况。
