大学生对两个原因交互作用效应的评估

College Students’ Assessing Interactive Influences of Two Causes on Effects

用大学生被试的两个实验考察人们对两个原因交互作用效应的定性评估和定量评估。实验结果表明，被试的定性评估与交互作用对比的性质相一致，而与因果力的性质不相一致；被试的定量评估随交互作用对比值增加而增加，而不受因果力的影响。实验结果一致支持交互作用对比标准，而不支持因果力标准和交叉乘积比率标准。这不同于以往的有关研究结果。

There are three main theoretical criteria of assessing interactive influences of two causes on effects: the cross-product ratio， the interaction contrast of Cheng and Novick’s (1990， 1992) probabilistic contrast model， and Novick and Cheng’s (2004) causal power theory. As to how human assess interactive influences of two causes on effects， there is no definite convincing conclusion in a few relevant studies on the issue. Two experiments were conducted to examine how college students would qualit
