Figure 3B illustrates amplitude variability in the two groups of participants at each time-point. Figure 3C illustrates α-band ITPC in the two groups of participants at each time-point. In order to compare these group time-courses, independent-samples t-tests were computed at each time-point. ITPC was significantly reduced (p < 0.05) in the participants with ASD between 160 and 271 ms after stimulus onset. Amplitude variability was significantly greater (p < 0.05) in the participants with ASD between 97 and 114 ms, between 185 and 194 ms, and between 283 and 300 ms after stimulus onset.
