爱情是自人类诞生以来就普遍存在的一个跨文化现象。爱情会引起个体神经内分泌状态以及神经功能等方面的变化，因此爱情对个体的行为和情绪都具有调节作用。但学界关于爱情对个体行为决策影响的研究却较为罕见。 为考察爱情对行为决策的影响，本文以跨期选择为研究对象，考察了爱情对人类跨期选择的影响作用。在论文的理论研究部分，首先对爱情的概念及相关理论、行为决策和跨期选择的概念、相关理论及国内外有关爱情和跨期选择的研究现状进行综述，总结出前人研究的不足；其次，分析了本研究的理论价值和实践意义。 在论文的实证研究部分，通过问卷调查考察了爱情对跨期选择的影响，主要包括两个研究：研究1是编制爱情和跨期选择的预测问卷，并对50名被试进行预测，并根据预测结果，修订问卷。研究2是考察恋爱状态和恋爱程度对时间折扣率的影响。 通过问卷调研我们主要得出了以下结论：（1）在“小金额”时，恋爱状态对折扣率的影响作用显著，“在恋爱中的个体”时间折扣率较高；（2）在“中金额”时，最大化倾向是恋爱程度与时间折扣的调节变量；（3）在“大金额”时，恋爱程度和时间折扣率具有显著的负相关，且恋爱程度对时间折扣率的影响存在性别差异，男性的时间折扣率显著高于女性。 这一研究结果不仅可以解释一些恋爱中的常见现象，如为什么大额花费主要由男方负担；并纠正一些常人对爱情的错误观念，如爱情让人短视、爱情让人盲目、恋爱中的人消费没有计划性等。该研究结果可对涉及爱情的消费行为的理论与应用具有指导意义，说明“爱情程度越高，人们越倾向对未来进行长久打算和准备”，可以为涉及跨期选择的销售和促销提供导向性的建议和决策支持。

Romantic love is a cross-cultural phenomenon since the birth of mankind. What’s more, romantic love can cause changes of individuals’ brain activity and neurohormone. As a result, romantic love affects individuals’ emotion and behavior. In other words, romantic love has a significant impact on individuals’ emotional state and behavior of decision-making. The research that bases on “The impact of romantic love on intertemporal choice” discusses the influence of love state on time discounting and the regulation of maximization by survey. The statistical results prove that romantic love has significant influence on individual’s decision-making. In the part of theoretical studies, we firstly reviewed the definition and theories of romantic love as well as decision-making and current researches on the influence of romantic love on decision-making both at home and abroad. Then, we summarized the merits and demerits in previous studies. Finally the thesis analyzed the theoretical and practical significance of this research. In the part of empirical studies, it explored the impact of romantic love on intertemporal choice by two studies. StudyⅠwas intended to design a questionnaire for testing the state and depth of subjects’ love and pre-tests 50 college students. Study Ⅱ was to revise this questionnaire and investigate the relationship of romantic love and intertemporal choice. The empirical studies came to the following conclusions: (1) For little money, the state of love showed significant effects on individual’s time discounting rate; (2) For moderate money, the correlation between the depth of love and individual’s time discounting rate was modulated by individual’s maximization tendency; (3) For big money, the depth of love showed significant negative correlation with time discounting rate. The writer hopes our research would throw a sprat to catch a herring. The research can lead more researchers to pay more attention to empirical studies on the influence of romantic love on individual’s behavior. Such researches will contribute to understand the definition of romantic love and its influence on individual’s daily life.
