Figures

Image of FIG. 1.
FIG. 1.

Rate discrimination performance in eight Med-El users using the mixed-block procedure. Solid circles: signal rates 35% higher than the baseline rate. Open circles: signal rates 20% higher than the baseline rate. Vertical bars represent 95% confidence intervals of the mean.

Image of FIG. 2.
FIG. 2.

Percent correct rate discrimination as a function of the percentage difference between signal and baseline rates (: open circles; : open inverted triangles; : open upright triangles; and : open squares). Results using the mixed-block procedure with at 35% are indicated by the closed symbols. Vertical bars represent 95% confidence intervals of the mean.

Image of FIG. 3.
FIG. 3.

Rate discrimination as a function of baseline rates in eight CI24 subjects (C1–C8). The mean data from the eight Med-El subjects (see Fig. 1) are replotted in the bottom rightmost panel along with the mean data from the eight CI24 subjects.

Image of FIG. 4.
FIG. 4.

Rate discrimination with SAM pulse train (closed circles) and equal-amplitude pulse train (open triangles) in five subjects. Note that subject M3 was tested on two different electrodes (El 3 and El 7). Vertical bars represent 95% confidence intervals of the mean.

Image of FIG. 5.
FIG. 5.

Rate discrimination on different electrodes on four subjects. Note that the signal rates are 35% higher than the baseline rates for subjects M1, M4, and M8, but only 20% higher for subject M3. The smaller difference between baseline rate and the signal rate used on M3 was to avoid the ceiling effect. Vertical bars represent 95% confidence intervals of the mean.
