Event-related oscillatory activity reflecting detailed-oriented perception during visual crowding in ASD. (A) Scalp maps displaying the oscillatory amplitude (i.e. power) in the beta band (15–30 Hz) separately in the ASD and TD groups, together with the p-values map on the right side showing the significant cluster-corrected differences between groups (*=cluster-corrected p < .05). This analysis was performed after subtracting the oscillatory power in the baseline task condition (no flankers displayed), in order to highlight effects that emerged specifically within a crowding regime (strong and mid). (B) Time-frequency plot of the event-related oscillatory power averaged across all significant electrodes, showing a sustained decrement of beta power in the TD group after the target onset, which was not evident in the ASD group (that actually showed the opposite trend). (C) A similar analysis performed in the alpha band (8–12 Hz) did not reveal any significant differences between groups.
