Corrigendum: The Social Reach: 8-Month-Olds Reach for Unobtainable Objects in the Presence of Another Person

Abstract

The test statistics (F and t) and p values reported in this article were inconsistent with one another because of errors copying values from previous drafts, missed lines in the SPSS output, and reference to outdated data sets and analyses during a protracted write-up process (2011–2016). These errors are now being corrected. The means for the main analyses were reported correctly in the original article, and the pattern of statistical significance and the interpretation of the findings remain unchanged. The authors apologize for the errors. The data sets on which the interpretation is based are posted at the Open Science Framework, https://osf.io/ msfcn/. The authors are also adding measures of effect size to the reported results: ηp 2 in the case of analyses of variance (ANOVAs) conducted in SPSS and unbiased Cohen’s ds and confidence intervals in the case of pairwise t-test comparisons. The latter effect-size measures were based on Cumming (2014) and were obtained using the calculators at https://thenewstatistics.com/ itns/esci/. In addition, oversights in the reporting of methods and errors in minor calculations are now being corrected.
