Results are shown from separate RM-ANOVAs conducted for investigating the effect of changing the speech rate on restoration benefit per age group. For an even comparison, these models included only interruption rates that overlapped between different speech rates, thereby excluding 10 and 20 Hz while comparing slow and normal rates, and 0.625 Hz while comparing normal and fast rates. Bold p values indicate significance below alpha of 0.05. IR and SR represent interruption rate and speech rate, respectively
