ERP waveforms illustrating N1 effects for cognitively able autistic and NT adults for target stimuli in a frontal ROI comprising the following electrode sites: F3, F4, Fz, C3, C4, and Cz. The time window used for the peak detection is illustrated by the gray bar over the x-axis (i.e., ms). 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 cognitively able autistic adults, a peak latency (indicated by arrow) difference was observed between short (blue) vs. long (red) presentation time, as indicated by the asterisk
