Figure 3.
Group mean proportions of question judgments as a function of the increment in peak intensity ratio, in the neutral condition (i.e., with a flat F0 contour). The x-axis indicates the steps of peak intensity ratio increments; the y-axis indicates the proportions of question judgments. Data points for the CI and NH groups, under the full-spectrum condition are displayed with circles and squares, respectively, linked with a solid line. Data points for the NH group under the 8- and 4-channel conditions are displayed with triangles and diamonds, respectively, linked with a dashed line.
