11 infants with Down's syndrome (MA 9.2 months, CA 12.7 months) and 10 of 11 nonhandicapped infants (MA 9.6 months, CA 9.3 months) demonstrated that they could operate an automated device which enabled them to choose to listen to 1 of a pair of auditory signals. All subjects showed preferential responding. Both groups of infants showed a significant preference for nursery rhymes sung by a female voice rather than played on musical instruments. The infants with Down's syndrome had much longer response durations for the more complex auditory stimuli. The apparatus provides a useful technique for studying language development in both normal and abnormal populations.
11名唐氏综合征婴儿（月龄9.2个月，实足年龄12.7个月）以及11名非残障婴儿中的10名（月龄9.6个月，实足年龄9.3个月）表明，他们能够操作一种自动化设备，该设备使他们能够选择收听一对听觉信号中的一个。所有受试者均表现出优先反应。两组婴儿都表现出对女性演唱的童谣而非乐器演奏的明显偏好。唐氏综合征婴儿对更复杂听觉刺激的反应持续时间长得多。该设备为研究正常和异常人群的语言发展提供了一种有用的技术。
