Estimates of the magnitude of the perceptual-separation advantage in experiment 1 for individual CI listeners (small points) and mean data for the vocoder conditions presented to NH listeners (white squares). Asterisks indicate the BI-CI listener who demonstrated significant interference when the interferer signals were presented to the second CI; this listener was excluded from the computation of the group-mean average (horizontal bars). Error bars indicate ±1 standard error of the mean across listeners.
