ERP results on the sensor level. A) GFP of conditions A and AV-V for CI-CHD users (red), CI-SSD users (green) and NH listeners (blue), including standard error. It is important to note that the GFP only provides positive values because it represents the standard deviation across all electrodes separately for each time point. The ERP topographies at the GFP peaks (N1(A) = CI-CHD: 147 ms, CI-SSD: 136 ms, NH: 118 ms; N1(AV-V) = CI-CHD: 137 ms, CI-SSD: 135 ms, NH: 118 ms; P2(A) = CI-CHD: 305 ms, CI-SSD: 288 ms, NH: 256 ms; P2(AV-V) = CI-CHD: 284 ms, CI-SSD: 307 ms, NH: 245 ms) are given separately for each group (displayed on the right). The grey-shaded areas represent the N1 and P2 time windows for detecting peak and latency. The grey bars below represent the time window in which significant GMDs between the three groups were observed.
