Experiments in which juvenile or adult barn owls are fitted with prisms that cause a mismatch between auditory and visual stimuli demonstrate that:
A) owls that learned a task as juveniles can relearn it as adults, and novel tasks can still be learned in adulthood as long as training is more gradual.
B) neural plasticity-in this case, the ability to adjust the auditory map-is completely lost by the time the owls reach maturity.
C) owls that adjusted their auditory maps to large mismatches with the visual field as juveniles can still do so if fitted with prisms as adults.
D) naive adults fitted with prisms are able to adjust their auditory maps to large mismatches with the visual field.
E) naive adults fitted with prisms are able to adjust their auditory maps in small increments.
