Mean and median stimulus levels associated with each category were used to determine within-subject reliability across two separate sessions. These comparisons were performed once with outliers included and again with outliers excluded. The reliability of the measurements was assessed using average stimulus-level differences, standard deviations of these differences, and correlations as shown.

	Average Stimulus-level Difference			Standard Deviation of Difference			Correlation Coefficient
	1 kHz	2 kHz	4 kHz	1 kHz	2 kHz	4 kHz	1 kHz	2 kHz	4 kHz
Mean without outliers	0.16	0.60	−0.61	7.6	6.6	7.8	0.95	0.95	0.94
Mean with outliers	0.17	0.64	−0.65	9.0	6.7	8.2	0.93	0.95	0.93
Median without outliers	0.18	0.81	−0.76	8.2	6.9	8.1	0.94	0.95	0.93
Median with outliers	0.24	0.86	−0.79	9.4	7.1	8.4	0.93	0.95	0.93
