Results of the standard event-related potential (ERP). The plot on the left side (a) illustrates standard ERPs at the P3 electrode during the reduced S-R task in the Covid group. The plot on the right side (b) illustrates standard ERPs at the P3 electrode during the reduced S-R task in the No Covid group. The alternation condition is illustrated in dark red colour during no overlapping trials and illustrated in dark blue in full overlapping conditions. Repeating trials are either illustrated in light red for no overlapping conditions or illustrated in light blue in fully overlapping conditions. While the x-axis displays the time in seconds (s) based on the onset of the target, the y-axis shows the ERP’s amplitude in μV/m². The scalp topographies illustrate the peak’s potential distribution, showing red colours for positive potentials and blue colours for negative potentials.
