Figures

Image of FIG. 1.
FIG. 1.

Scores averaged across subjects for experiment 1 in which the target was a tone, and the background was a noise with a small notch at the target frequency. The percentage correct is plotted as a function of partial number. The probe tone and the target tone within the complex sound were either presented as a single long pulse (crosses) or as three pulses with 100-ms gaps (circles) (illustrated schematically at the top).

Image of FIG. 2.
FIG. 2.

Scores averaged across subjects for experiment 2 in which the background was composed of multiple partials, and all partials in both the target and background were irregularly and independently amplitude modulated. The percentage correct is plotted as a function of partial number. Each symbol shows results for one pulsing condition of the probe and target. The conditions are indicated schematically on the right.

Image of FIG. 3.
FIG. 3.

Comparison of results from experiment 2 (triangles), experiment 3 (squares), and Moore et al. (2009 , circles). Mean scores for the nine inner partials are plotted as a function of the duration of the gaps in the probe and target.

Image of FIG. 4.
FIG. 4.

As Fig. 2 but showing scores for experiment 3 in which only the target had irregular amplitude modulation.

TABLE I.

Scores (percent correct) for experiment 1 averaged across the inner partials for the condition where the target tone was presented as a single pulse, and where it was presented as three pulses separated by 100-ms gaps. The width of the notch in the background noise and the level of the target tone were chosen separately for each subject on the basis of pilot trials in an attempt to give performance in the range between 55% and 95% correct; two or three combinations were used for each subject. SD means standard deviation.
