Note: Reported p values are uncorrected, but all t tests were still significant after a Holm-Bonferroni correction. See Schönbrodt and Wagenmakers (2018) for a classification scheme for the interpretation of Bayes factors. We calculated the Bayes factors with the BayesFactor package in R using the default prior (0.707). Significant p values are boldfaced. CI = confidence interval.
