Event-related potential (ERPs) results. (A, B) Target evoked ERPs as a function of task conditions in the ASD and TD groups; data were obtained by averaging the activity in the posterior electrodes of interest (see upper-left insets). Activity in the grey shaded window in the time period 150–250 ms (N1) relative to the target onset was found to be differently modulated in the two groups as a function of task conditions. (C) Mean amplitude of this N1 ERP component as a function of group and task condition, revealing that while visual crowding modulated the amplitude of this component in the TD group, this modulation was absent in the ASD group (error bars represent SEM; * = p < .05).
