ERP waveforms illustrating N2 effects for cognitively able autistic and NT adults for target stimuli in a ROI using the following electrode sites: Fpz, Fp1, Fp2, AFz, AF3, AF4, Fz, F1, and F2. A repeated measure ANOVA was performed for each group with the factors: category (animal vs. food), typicality (typical vs. atypical), and presentation time (23.5 vs. 82.3 ms). In both groups, we observed differences between the animal vs. the food category. A ERPs. The time window used for the mean activity is illustrated by the gray bar over the x-axis (i.e., ms). In both groups, we observed differences between animal (blue) vs. food (red) images, as indicated by the asterisk. B Topographical maps. Electrode sites are marked with circles; filled circle indicates the ROI for this analysis
