我们报告了一个多年项目的第一组结果,以评估成人统计分词文献的稳健性-以及促进稳健性的因素。这包括总共八个实验,重复六个不同的实验。这些重复的目的是评估已报道的实验的重复性,检查其结果的可重复性,并提供更准确的效应大小估计。重现性好坏参半,有几篇论文要么缺乏关键细节,要么在方法描述中存在错误,使得很难确定做了什么。可复制性也是参差不齐的:尽管在每一个例子中,我们都确认了概率统计分词,但许多理论上重要的学习节制未能复制。此外,学习成功率总体上比最初的研究要低得多。在一般性讨论中,我们考虑这些差异是由于受试者群体的差异,原始研究的低功率,还是这些因素和其他因素的某种组合。我们还考虑了这些发现是否可能推广到更广泛的统计分词文献中。
We report the first set of results in a multi-year project to assess the robustness – and the factors promoting robustness – of the adult statistical word segmentation literature. This includes eight total experiments replicating six different experiments. The purpose of these replications is to assess the reproducibility of reported experiments, examine the replicability of their results, and provide more accurate effect size estimates. Reproducibility was mixed, with several papers either lacking crucial details or containing errors in the description of method, making it difficult to ascertain what was done. Replicability was also mixed: although in every instance we confirmed above-chance statistical word segmentation, many theoretically important moderations of that learning failed to replicate. Moreover, learning success was generally much lower than in the original studies. In the General Discussion, we consider whether these differences are due to differences in subject populations, low power in the original studies, or some combination of these and other factors. We also consider whether these findings are likely to generalize to the broader statistical word segmentation literature.
