  1. Sensitivity analyses are reported for paired-sample t tests and mixed method ANOVAs, separately for behavioral and ERP analyses. We used the lowest observed pairwise relationship among within-subject factors to obtain conservative estimates of the lowest effect size our analyses would be able to detect. Effect sizes for t test are reported in Cohen's d, effect sizes for ANOVAs are reported in Cohen's f
