Description: We report the first set of results in a multi-year project to replicate every adult statistical word segmentation study. We reported replications of six experiments. The purpose of these replications is both to assess the strength of the findings in the statistical learning literature but also to provide more accurate effect size estimates. In every instance, we were able to replicate successful learning. However, many theoretically important modulations 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 other factor. Regardless, these initial results suggest taking caution in relying on the originally reported findings.
