Figure 5.

Effect of training on auditory localization accuracy. A, Magnitude of the unsigned errors averaged for all incorrect trials and speaker locations over 10 consecutive training sessions for NH ferrets, and for ferrets with early-onset deafness that were fitted with a UniCI (n = 2) or BiCIs (n = 2) as adults. Each symbol represents a different animal. HL, Hearing loss. B, Equivalent data for ferrets with late-onset deafness and a UniCI (n = 2) or BiCIs (n = 2). In each case, the slopes of the fitted regression lines did not differ either between the groups (ANCOVA, p = 0.6) or from zero (t tests, p = 0.59).
