Table 5.

Results of linear mixed effects modeling on correct and incorrect trials of reaction times. Group differences between listeners with NH and CIs with unprocessed (Full Spectrum) stimuli are shown on top. Results from NH listeners in the different conditions of spectral degradation are shown in the lower part. In the interest of clarity, only significant effects are shown.
