Table 2.

Fits to child data, by stimulus condition. The parameter m is the slope defining improvement in threshold (log of duration in ms) as a function of age (log of age in yrs) in young listeners. The parameter d is the age (yrs) at which that line reaches the adult mean. The standard error of the mean is indicated below each parameter estimate.
