The extent to which the participants with ASD showed increased variability when compared with the neuro-typical participants was investigated with three 2 × 2 repeated measures ANOVAs with a within-subject factor of data source (CSD or ICA) and a between subjects factor of group (ASD or TD). The results of these analyses are shown in Table 3, and the data are plotted in Figure 3A. The participants with ASD showed, on average, greater variance than the neuro-typical participants. This was the case for both measures of P1 variability: amplitude variability, ASD mean = 0.38 [0.33 0.43], TD mean = 0.30 [0.25 0.35]; latency variability, ASD mean = 0.07 [0.05 0.08], TD mean = 0.04 [0.03 0.06]; and also for the maximum α-band ITPC, ASD mean = 0.74 [0.66 0.83], TD mean = 0.87 [0.78 0.96].
