FIG. 3.

Pooled plots of the variation of raw phase lag against CF in which the phase values at all sound levels measured are overplotted (note, there is no added shift in this figure, unlike Figs. 4 and 11). The frequencies displayed are at one quarter octave intervals starting at 250 Hz (250, 353, 500, 707, 1,000, 1,414, and 2,000 Hz). The top black symbols represent the 250-Hz data and the bottom black symbols represent the 2000-Hz data. The triangles indicate the stimulus frequency for the different plots and are placed by eye at the middle of the appropriate data and given the contrasting color.
