ERP responses This figure shows ERP waveforms in response to novel (red line) and familiar (yellow line) stimuli. The infants who later recalled how to assemble a toy (left panel) had clearly discriminated between the familiar and novel items on an earlier recognition test. The infants who did not recall the assembly sequence (right panel) had not discriminated between the components on the earlier test. (Adapted from L. J. Carver, Bauer, & Nelson, 2000)
