Table 5.

Results of Nonoverlap of All Pairs (NAP) analyses for the three prosodic measures that differed across groups. Values are expressed in the direction of the mean/median difference, such that 0.5 indicates complete overlap and 1.0 indicates no overlap. Significance values indicate the probability that a randomly chosen measure in one group will be greater (or lesser) than one chosen from the other group.
