Figure 1.

Obtained decision weights for two-interval, forced-choice identification of target plates are given for each listener (panel rows) for the low-pass condition of experiment 1. Error bars give the standard error of estimate in each case. Dotted lines give the ML weights. The two panel columns give the decision weights separately for the change in frequency and change in decay of each partial. Performance levels (PC and d^′) are also indicated for each listener.
