自我损耗对冲动购买的影响:解释水平的作用

The Effect of Ego Depletion on Impulse Buying:The Role of Construal Level

目的:探讨解释水平是否为自我损耗影响冲动购买的具体心理机制,为整合自我损耗的有限资源模型和过程模型提供启示。方法:实验1检验自我损耗对冲动购买的影响。实验2通过因果链设计分段考察了自我损耗对解释水平的影响(实验2a),以及解释水平对冲动购买的影响(实验2b)。实验3探讨了解释水平在损耗影响冲动购买中的中介作用。结果:(1)自我损耗会诱发个体低解释水平;(2)低解释水平会导致个体更高的冲动购买水平;(3)解释水平是自我损耗影响冲动购买的中介机制。结论:自我损耗以解释水平为中介,促进冲动购买。

Objective:To explore whether the construal level is the psychological mechanism of ego depletion effect on impulse buying and provide inspiration for integrating limited resource model and motivation process model of ego depletion.Methods:Experiment 1 examined the effect of ego depletion on impulse buying.Through a causal chain design,Experiment 2 examined the effect of ego depletion on construal level(Experiment 2a)and the effect of construal level on impulse buying(Experiment 2b).Experiment 3 explored the mediating role of construal level in the effect of ego depletion on impulse buying.Results:(1)Ego depletion reduced the construal level;(2)Low construal level promoted impulse buying;(3)Construal level was the mediating mechanism of ego depletion affecting impulse buying.Conclusion:Ego-depletion,mediated by construal level,promotes impulse buying.
