Figure 5: MRCPs differ across age groups. (A) Statistical cluster plots illustrating scalp locations in which statistically significant differences were observed as a function of age bin in TD participants (left) and ASD participants (right). (B-D) Representative electrodes showing MRCP differences by age group for TD participants (left) and the corresponding electrode for ASD participants (right). Gray bars indicate statistical differences. (B) Left fronto-central electrode FC3. (C) Mid-frontal electrode Fz. (D) Left parietal electrode P3. (E) Scalp topography plotted separately for TD (left) and ASD participants (right) averaged over the timewindow from 200 ms to 150 ms before the button press. Topographies were stratified by age bin (rows) from youngest (top row) to oldest (bottom row). (F) Statistical cluster plot illustrating significant between group differences between ASD and TD participants separately for each age bin. (G) Average scalp topographies constructed over the timewindow of 25 to 75 ms after the button press.
