aMean value ± standard error.
bEpsilon presented only if sphericity is not assumed (Mauchly’s test <0.05).
cIf sphericity is not assumed, the Greenhouse–Geisser results are presented for ε < 0.75 and the Huynh–Feldt results are presented for ε > 0.75.
dIncluding Bonferroni correction. Only significant results are presented.
