Online experiments have recently become very popular, and--in comparison with traditional lab experiments--they may have several advantages, such as reduced demand characteristics, automation, and generalizability of results to wider populations (Birnbaum, 2004; Reips, 2000, 2002a, 2002b). We replicated Dandurand, Bowen, and Shultz's (2004) lab-based problem-solving experiment as an Internet experiment. Consistent with previous results, we found that participants who watched demonstrations of successful problem-solving sessions or who read instructions outperformed those who were told only that they solved problems correctly or not. Online participants were less accurate than lab participants, but there was no interaction with learning condition. Thus, we conclude that online and Internet results are consistent. Disadvantages included high dropout rate for online participants; however, combining the online experiment with the department subject pool worked well.
在线实验近来变得非常流行，并且——与传统实验室实验相比——它们可能具有若干优势，比如需求特征减少、自动化以及结果对更广泛人群的可推广性（伯恩鲍姆，2004；赖普斯，2000、2002a、2002b）。我们将丹杜兰德、鲍温和舒尔茨（2004）基于实验室的问题解决实验复制为一项互联网实验。与先前结果一致，我们发现观看成功解决问题环节演示的参与者或阅读说明的参与者比那些仅被告知他们是否正确解决问题的参与者表现更好。在线参与者的准确性低于实验室参与者，但与学习条件不存在交互作用。因此，我们得出结论，在线和互联网实验结果是一致的。缺点包括在线参与者的高退出率；然而，将在线实验与系里的受试者库相结合效果良好。
