Cumulative gamma functions fitted by MLE to the behavioral data associated with the eight stimulus spokes at each of the three SNR values are shown in thick black lines. The GPR-VTL trading parameter was allowed to vary along with the parameters describing the gamma functions. The optimized trading value was 1.9. Performance is plotted as a function of the RSD (RSD1.9) in logarithmic units. The mean data for the individual spokes are shown by the gray lines. The dashed lines are for an SNR of 6 dB; the solid lines are for 0 dB SNR and the dotted lines are for −6 dB SNR.
