Using VEPs, Wattam-Bell et al. showed when stimuli changed between 0% and 100% coherence:

A) Responses to changes in form and motion were adult-like at 3 weeks
B) Responses to changes in form, but not to motion, were adult-like at 3 weeks
C) Responses to changes in form and motion were adult-like at 5 months
D) Responses to changes in motion were adult-like 5 months in all infants, with those to form adult-like in only about half the infants
