a strong trend toward significancep = 0.065
Post-hoc t -tests showed that omissions occurred more frequently than substitutions and confusions [ t (1, 111) = 18.61, p < 0.001, t (1, 111) = 15.7 p < 0.001], and that the listener two groups showed a significant difference for substitutions [ t (1, 111) = 3,05, p = 0.03], a strong trend toward significance for omissions [ t (1, 111) = 1,86, p = 0.065] but no significant differences in confusions ( p < 0.05).
