Scores averaged across subjects for experiment 1. The percentage correct is plotted as a function of partial number (see Table I for frequencies of partials). Within each panel, the parameter is the pulsing pattern of the probe tone and the target tone within the complex (illustrated schematically on the top-right). Each panel shows results for one spacing of the partials, as indicated in the key.
Scores for experiment 1 averaged across all inner partials and plotted as a function of the spacing of the partials. The parameter is the pulsing pattern of the probe tone and the target tone within the complex, as indicated in the key.
As Fig. 1, but showing scores for experiment 2, in which subjects had to identify which of two complex tones contained a pulsed partial.
As Fig. 2, but showing results for experiment 2.
IR for the complex tones used in four different conditions, with the sixth partial pulsed. Time is plotted on the -axis, channel CF is plotted on the -axis, and darkness-brightness shows excitation in MUs (see scale on the right). The spacing of the partials was either (left) or (right). The two pulsing conditions were 40-ms ramps, 0-ms gaps (top) or 20-ms ramps, 100-ms gaps (bottom).
The MED plotted as a function of -spacing, with pulsing condition as parameter. The data points are based on the mean values of the MED obtained when partial numbers 3, 6, and 9 were pulsed. Error bars show the standard deviation of the MED across the three partials.
The MED plotted against the corresponding mean value obtained for each pulsing condition and spacing in experiment 2. Error bars show the standard deviation of the MED across partials 3, 6, and 9.
Frequencies (Hz) of the partials in the complex tones for each spacing used. The frequency of the middle partial is given in bold type.
