Average ERP waveforms in response to the visual stimuli in infants (12-15-month-olds) and young adults. Average ERP waveforms ± s.e.m, computed from the same data epochs that were used to perform within-subjects classification. In contrast to within-subjects classification, amplitudes were not z-scored, and were averaged over electrodes of interest. Thick (resp. thin) black horizontal lines indicate significant (resp. marginally significant) clusters for the difference in average amplitude in response to animals vs. body items (two-tailed).
