highly significantp = .0005
A one-way ANOVA showed a highly significant cohort effect ( F = 14.20, p = .0005, η 2 = 0.69), and a pairwise post-hoc Tukey-HSD test computed with the onset indices for the ND-CI and AD-CI cohorts were not significantly different ( p = .98), but did reveal a significant difference between ND-CI and NH-acoustic ( p = .0007) and AD-CI and NH-acoustic ( p = .0018).
