Context-dependent M100 response magnitudes. A, Responses to different sound levels in the 15 and 45 dB SL contexts. B, Response range (calculated as the difference between the maximum and the minimum amplitude) in the 15 and 45 dB SL contexts. The main effect of age group and the main effect of context was significant (p < 0.05; no interaction). C, Difference in response magnitude between the 15 and 45 dB SL contexts for each sound level separately. The colored asterisks mark (*) levels at which responses were significantly larger (i.e., more positive) in the 15 dB SL compared with the 45 dB SL context (p < 0.05, FDR corrected). Error bars indicate SEM.
