Table 2.
Bayesian repeated measures ANOVA statistics. Bayes factors with percentage error for main effect and interaction models, and post hoc comparisons. All models are compared to the null model including hemisphere as a nuisance variable (H0; no effect). The posterior odds were corrected for multiple comparisons in the post hoc comparisons. Bayes factors >3 are bolded to indicate evidence for an effect (in favour of H1).
