条件信息同样可以以 if p, then q（例如，“如果我生病了，我明天会错过工作”）和 q, if p（例如，“如果我生病了，我明天会错过工作”）的形式断言。虽然以前发现这种类型的子句顺序操作对参与者从条件规则中得出的最终结论没有影响，但我们使用自定进度阅读来检查它如何影响日常条件语句的实时增量处理。实验 1 表明，当读者假设地表示反事实陈述时，子句顺序与预设一致性相互作用。当 if p, then q 反事实包含与先前上下文不一致的预设时，这些陈述的阅读时间比预设一致时要长，但对于 q, if p 条件句则不存在这种一致性效果。实验2表明，无论从句顺序如何，阅读时间都会受到指示性条件句的主观概率的影响，在两种条件从句顺序中，相对于高概率陈述，观察到低概率陈述的惩罚。这些数据揭示了一种分离，即子句顺序调节假设一致性对阅读时间的影响，但不调节主观概率的影响。
Conditional information can be equally asserted in the forms if p, then q (e.g., "if I am ill, I will miss work tomorrow'') and q, if p (e.g., "I will miss work tomorrow, if I am ill''). While this type of clause order manipulation has previously been found to have no influence on the ultimate conclusions participants draw from conditional rules, we used self-paced reading to examine how it affects the real time incremental processing of everyday conditional statements. Experiment 1 revealed that clause order interacts with presuppositional congruency as readers hypothetically represent counterfactual statements. When if p, then q counterfactuals contained a presupposition that was incongruent with prior context, these statements took longer to read than when the presupposition was congruent, but for q, if p conditionals there was no such congruency effect. Experiment 2 revealed that reading times were influenced by the subjective probability of an indicative conditional regardless of clause order, with a penalty observed for low-probability statements relative to high-probability statements in both conditional clause orders. These data reveal a dissociation whereby clause order mediates the effect of suppositional congruency on reading times, but does not mediate the effect of subjective probability.
