title: The visually evoked potential in response to vernier offsets in infants.
abstract: The visually evoked potential (VEP) was recorded from infants (1 month 25 days to 13 months 3 days) in response to vernier offsets, motion displacements, and a stationary stimulus which served as a noise control. The records were analyzed by five masked adult observers familiar with VEP recordings using a signal detection method. The results suggest that a VEP can be recorded from infants in response to a vernier offset and the response resembles that obtained from adults tested with the same procedure. However, unlike adults, infants also showed a response to a motion displacement of the same magnitude suggesting that infants may not show the same specificity for the break in colinearity characteristic of the adult VEP.
