Table I.
Root-mean-square error (RMSE) in μs between the mean thresholds and model predictions. MTF and No-MTF refer to the binaural ROC models with and without modulation filtering and half-wave rectification, respectively. The RMSEs for the prediction averaged over the three SR fiber types are listed in the column “Mean SR”, whereas the RMSEs for the weighted average according to the prevalence of the three fiber types in cats (Low SR: 16%, Medium SR: 23%, High SR: 61%; Liberman, 1978) are listed in the column “Weighted mean SR”. The upper four rows show the RMSEs for the prediction across Cs from the present study, whereas the lower rows show the RMSEs for attack and pause duration experiments in Klein-Hennig et al. (2011). The RMSEs for the normalized cross-correlation coefficient (NCC) model, the NCC model with five adaptation loops (NCC5A) and with the first adaptation loop only (NCC1A) were replicated from Table I in Klein-Hennig et al. (2011). The parenthesized criterion indicates that the ITD prediction of high SR fibers for the 0-ms pause duration was infinitely large due to the completely flat AUC-vs-ITD function, which prevented the systematic estimate.
