本题考查对学术文章引言部分句子功能的理解。解题的关键在于准确分析每个句子在段落中的作用，判断其是对前人研究的描述、当前研究的假设、目的还是方法。

1. 文章第一句 “Most previous studies on academic dishonesty have relied primarily on self - reports of cheating behaviors.” 表明以往关于学术不端的研究主要依赖作弊行为的自我报告，这是对前人研究方式的阐述，可看作是对前人研究局限性的一种体现。
2. 括号内的句子 “The present study includes an empirical portion in which participants are put in a situation in which cheating may be to their advantage.” 详细说明了当前研究包含一个实证部分，并且会让参与者处于作弊可能对他们有利的情境中。这清晰地描述了当前研究采用的具体方式，即通过实证实验来进行研究，所以该句子的功能是介绍当前研究的方法。
3. 第三句 “I hypothesize that participants would be most likely to cheat when they are offered a monetary reward for success.” 明确提出了假设，即当为成功提供金钱奖励时，参与者最有可能作弊。
4. 最后一句 “The purpose of the study is to investigate participants' attitudes towards cheating and the effects of academic motivation, self - efficacy and academic integrity on cheating behaviors.” 说明了研究的目的是调查参与者对作弊的态度以及学术动机、自我效能和学术诚信对作弊行为的影响。
