中文摘要：

反事实思维是对过去发生事情进行否定而产生的假设性思维表征，对行为改变和绩效改善有显著影响。因此，作为一种重要的认知策略，反事实思维常常被用于行为干预的研究。本研究采用单因素（反事实启动／经验启动）被试问实验设计，以4种常见的行人不安全行为为实验材料，运用顺序启动范式的语义启动分别激活自变量的两个水平，将遵守交通规则行为意向的评分和反应时双变量作为因变量指标，探索反事实思维对行人安全行为的促进作用。结果表明：与基线水平和经验启动相比，反事实启动诱导产生的行人交通安全行为意向更加积极，并且产生的自动化水平更高。文章最后讨论了研究的理论意义和对安全管理实践的启发。

英文摘要：

Counterfactual thinking refers to the mental representations of alternatives to past events. It plays an important role in changing behaviors and improving performance by converting information about past mistakes into plans for future actions. As an important cognitive strategy, counterfacmal thinking is used in behavioral interventions. The current study explores whether counterfactual thinking, which has a behavior-regnlating function, improves the behavioral intention of pedestrians. Four frequent unsafe behaviors of pedestrians were chosen as the experimental materials. A one-factor between-subjects study was designed. The participants were randomly divided into two groups, namely, the experimental （counterfactual priming） and the control （experience priming） groups. To match the sample from the experimental and control groups, we excluded the effect of individual differences and measured the baseline of all the participants based on factual thinking, that is, their intention to follow a traffic rule （rating on a 6-point Likert scale） and their reaction time in rating. Next, a modified sequential priming paradigm was applied to prime the counterfactual thinking （experimental condition） or past experience （control condition） of the participants. The participants were then asked about their intention to follow the traffic rule again. As dependent variables, both the behavioral intention and reaction time were recorded again. The results showed that the intention of all the participants to follow traffic rules was positive. A paired-sample t-test was conducted to test the differences in intention and reaction times between the baseline and the two treatments. The rating scores and reaction times in baseline and experimental conditions showed significant differences. Specifically, the behavioral intention of the experimental group was more pOsitive and their reaction time in rating was faster than those in the baseline. However, the rating scores in the baseline and control conditions showed
