Question

Quizplus · Accepted Answer

Infants less than 10 days old can distinguish their mother's voice from other voices and will alter their behaviour to hear her voice. This suggests they have some auditory perception, but they do not have the full auditory acuity of an adult. They also do not have full visual perception, so options C and D are incorrect.
