Table 1.

Frequency of reaching test criterion per age group and ripple depth

10 dB 20 dB
3-month-olds (n=18) 88.9% (33.3%) 100% (72.2%)
7-month-olds (n=15) 93.3% (46.7%) 100% (86.7%)
Young adults (n=14) 100% (100%) 100% (100%)

Note: Percent of participants who reached criterion for at least one test phase shown (percent who reached criterion for at least two test phases shown in parentheses). Based on simulated probabilities of 0.125 for reaching criterion for one test phase, each percentage was greater than chance (binomial exact p’s < 0.0001).
