A unitary model of auditory frequency change perception
Fig 6
Model results and human listeners across all experiments.
The y-axis shows the proportion of “down” responses. The x-axis indicate shift size; for two-dimensional shifts, pairs indicate shifts along the SFS and SE dimension, respectively. The rows index the properties of the fine structure (harmonic, inharmonic (Exps. 1&2) and log-equidistant (Exp. 3). The columns index the shift type, one-dimensional SFS or SE, and two-dimensional SFS-SE with average data from human listeners and the model plotted in thick and thin colored lines, respectively. Raw predictions from the AC, CCres, and CCunres cues as indicated in the legend. R2 values for correlation between average model and empirical data (omitted for log-equidistant SFS and SE shifts of Exp. 3 due to insufficient number of shifts). R2 values for raw cues are provided in Table E in S1 Text.
