本研究提出了一种方法来检验因果假设，称为回归不连续性分析，在调查人员无法随机分配的实验组和对照组的情况下。这些学生是从几乎获胜的学生中选出的--5126名获得优异证书的学生和2848名仅获得表扬信的学生。新分析模式所得结果与对相同数据采用事后设计所得结果的比较。新的分析表明，公众对成就的认可往往会增加获奖者获得奖学金的可能性，但并不支持认可影响学生态度和职业规划的推论。摘自《心理学文摘》36：01：1AF 09 T。（PsycInfo数据库记录（c）2022阿帕，保留所有权利）
This study presents a method of testing casual hypotheses, called regression-discontinuity analysis, in situations where the investigator is unable to randomly assign Ss to experimental and control groups. The Ss were selected from near winners—5126 students who received certificates of merit and 2848 students who merely received letters of commendation. Comparison of the results obtained from the new mode of analysis with those obtained when the ex post facto design was applied to the same data. The new analysis suggested that public recognition for achievement tends to increase the likelihood that the recipient will receive a scholarship but did not support the inference that recognition affects the student's attitudes and career plans.
