d′ data across children for 300-ms sweeps of ±2 (most-left) ±4 (middle-left), ±8 (middle-right), and ±16 (most-right) semitones/sec, in two tasks where the child was asked to label the direction of a single sweep (top panels) or discriminate between sweeps of opposite direction (bottom panels). Means are on the right-hand side of each panel, and error bars represent one standard error. A higher d′ reflects a more acute sensitivity. At these rates, none of the regressions reached significance among children with CIs, and age effects were stronger for NH children in the US than in Taiwan.
