　　托福阅读修辞目的题：Studying Infant Perception

　　【Paragraph 1】In the study of perceptual abilities of infants, a number of techniques are used to determine　infants' responses to various stimuli. Because they cannot verbalize or fill out questionnaires, indirect techniques of　naturalistic observation are used as the primary means of determining what infants can see, hear, feel, and so forth.　　Each of these methods compares an infant's state prior to the introduction of a stimulus with its state during or　immediately following the stimulus. The difference between the two measures provides the researcher with an　indication of the level and duration of the response to the stimulus. For example, if a uniformly moving pattern of　some sort is passed across the visual field of a neonate (newborn), repetitive following movements of the eye occur.　The occurrence of these eye movements provides evidence that the moving pattern is perceived at some level by the　newborn. Similarly, changes in the infant's general level of motor activity —turning the head, blinking the eyes, crying,　and so forth — have been used by researchers as visual indicators of the infant's perceptual abilities.(Methods of　Studying Infant Perception)

　　Why does the author mention repetitive following movements of the eye?

　　○To identify a response that indicates a neonate's perception of a stimulus

　　○To explain why a neonate is capable of responding to stimuli only through repetitive movements

　　○To argue that motor activity in a neonate may be random and unrelated to stimuli

　　○To emphasize that responses to stimuli vary in infants according to age
