Table 1.

Results of repeated measures ANOVA showing protected post hoc comparisons between baseline and FI conditions separately for each group (top), and between participant groups separately for each phase (bottom). Double asterisks indicate tests significant at FDR q=.01.

Note. %SS = observer-judged percent syllables stuttered; SFSPM = observer-judged stutterfree speech rate; NA = observer-judged speech naturalness, 1–9; EFFORT = self-rated speech effort, 1–9. PWS = Persons who stutter; CONT = Control group.
