Seven-month-old infants listened to a regular repeating ambiguous rhythm while they were bounced up and down at two bounces per beat or at three bounces per beat. Later, they were tested to see how they had perceived the rhythm. The results suggest that _____.

B) the infants always perceived the rhythm as occurring in twos
C) the infants' perception was influenced by how they were bounced
D) the vestibular system is not involved in auditory perception and movement

Question

Quizplus · Accepted Answer

The fact that the infants' perception was influenced by how they were bounced indicates that their vestibular system (which controls balance and spatial orientation) played a role in their perception of the rhythm. A and B are incorrect because the study found that the infants' perception of the rhythm was not consistent or fixed, but rather influenced by external factors. D is incorrect because the study actually suggests the opposite - that the vestibular system is involved in auditory perception and movement.
