3、e 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 infants s
4、tate 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 s
5、ort 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 infants general level of motor activity

10、eing observed. At that point a new stimulus is presented, and any recovery (dishabituation) in responsiveness is recorded. If the infant fails to dishabituate and continues to show habituation with the new stimulus, it is assumed that the baby is unable to perceive the new stimulus as different. The

14、实信息题，答案是(A)。解析：题干关键词先有habituation-dishabituation大致定位，发现出现多次，再由 differentiate缩小范围，与第四句的different是相同意思，因此定位于第四句(如果婴儿没有显出对新刺激的不适应而继续表现出适应性，就说明他们不能区分新的不同的刺激)，反之，A所说的“当对新的刺激不适应时，婴儿就能够区分刺激了”也是对的。B项定位倒数第二句，讲的是第二种技术，而题干问的是第一种，D项说的也是第二种，C则与原句相反。易错选项：(B)。以上就是小编带来的托福阅读笔记之TPO13 Methods of Studying Infant Perception，希望能够和备考的大家一起学习。更多托福考试资讯请关注前程百利。友情提示：部分文档来自网络整理，供您参考！文档可复制、编辑，期待您的好评与关注！4 / 4
