Although Figure 6 shows that Chk tokens of right tend to end in a steeply rising pitch, the RMANOVA tests yield between-subjects p-values of 0.01 or lower, indicating substantial speaker effects.
even though the general tendency for these tokens, as indicated by both the numeric and categorical variables, seems to be to end in a high-rising intonation, there is evidence of different behavior for some individual speakers, which keeps us from drawing general conclusions about this pragmatic function of right.
