Schematic illustration of the stimuli. (a) 3-stimulus paradigm with the stimulus in black and the expected neural response in red. The transitions between the stimuli (S1, S2, S3, pause) were expected to evoke the onset response, the acoustic change complex (ACC) related to amplitude modulation detection (AMD), the ACC related to amplitude modulation frequency discrimination (AMFD), and the offset response; (b) 2-stimulus paradigm with the stimulus in black and the expected neural response in red. The transition between the alternation stimuli (S2, S3) was expected to evoke an ACC related to AMFD; (c) Levels of the unmodulated stimulus (C_unmod, T_unmod) and the modulated stimulus (C_mod, T_unmod).
