Note. CI1 = first cochlear implant; CI2 = second cochlear implant; Bil = bilateral; Q = quiet; N = noise; P = prebilateral interval; 1–24 indicate postbilateral intervals. Significant differences (from zero or between CI conditions) are indicated with an asterisk or an asterisk followed by the test intervals for which significant differences occurred. For example, on Words Q (first row), the first three significant findings columns indicate the quadratic component of the CI2 curve (but not CI1 or bilateral) was significantly different from zero (straight). The three far-right columns indicate that the CI2 quadratic curve component was significantly different from that of CI1 and bilateral, which were not significantly different from each other. In the second row, CI1, CI2, and bilateral linear slopes (rate of change) were significantly different from zero at 12; at P, 3, 6, and 12; and at P, 3, 6, and 12, respectively. CI2 linear slope differed significantly from CI1 and bilateral at P, 1, 3, 6, and 12. CI1 linear slope did not differ significantly from bilateral at any interval. Significant differences for intercept are indicated in the same manner as for linear slope. Only significant post hoc results following significant overall tests are indicated.
