Before revision:  Conversely, a modified spectral model considering a predictive interaction between frequency and FM encoding fully reproduces our and previous experimental data .
After revision:  Conversely, a modified spectral model considering a predictive interaction between the sweep and the spectral representation. To test this hypothesis, we developed a novel model of FM encoding incorporating a predictive feedback mechanism. The model fully accounted for experimental data that we acquired in a perceptual experiment with human participants as well as previously published experimental results. We also designed a new family of stimuli for a second perceptual experiment to further validate the model .
