When the Mother Is Standing Over the Crib Where the Infant

When the mother is standing over the crib where the infant is, Jerome Bruner observed that the three to eight-week-old baby will become agitated and begin to cry if the infant hears the mothers' voice coming from a loudspeaker rather than from the mother's mouth. This illustrates that babies

A) are startled by loud noises.
B) have more acute vision than was previously thought.
C) seem to understand that a person's voice and body should be connected.
D) are unable to localize and predict where sounds should come from.
