Survival functions, cumulative proportion of participants reaching criterion, for infants (top) and adults (bottom) for voicing and place of articulation contrasts, in quiet and in noise. A single point is plotted for infants at 8 Hz, because all infants tested on the voicing contrast in noise reached criterion at 256 Hz. A single point is plotted for adults at 8 Hz, because all adults tested on both contrasts in quiet reached criterion at 256 Hz and at 8 Hz and the symbols for the two conditions are overlaid. Error bars are standard errors from the Kaplan-Meier analysis.
