This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). The authors discovered from comments on their open data that Studies 1 and 2 of their manuscript suffered from a serious flaw. There was a mistake in the Python code they used, and the items (vignettes) were not properly randomized across conditions. In Study 1 (which investigated the effect of cognitive load on moral judgment), all participants in the Load condition received one set of items, whereas all participants in the No Load condition received a different set of items. This meant that they cannot determine whether the difference they observed between the Load and No Load conditions was due to the manipulation (Load vs. No Load) or to a simple difference between items. Given these problems, the authors cannot guarantee that the conclusions of their paper are valid. Because of this error, the authors have requested retraction of their manuscript.
请参阅爱思唯尔的撤稿政策(http://www.elsevier.com/locate/withdrawalpolicy)。作者从他们的公开数据评论中发现,他们手稿的研究 1 和研究 2 存在严重缺陷。他们使用的 Python 代码有误,项目(小品)在条件之间没有正确随机化。在研究 1(研究认知负荷对道德判断的影响)中,负荷条件下的所有参与者都收到了一组项目,而无负荷条件下的所有参与者都收到了一组不同的项目。这意味着他们无法确定他们在负荷和无负荷条件之间观察到的差异是由于操作(负荷与无负荷)还是项目之间的简单差异造成的。由于这个问题,作者不能保证他们论文的结论是有效的。由于这个错误,作者要求撤回他们的手稿。
