The data to be discussed in this paper are drawn from a study of three groups of infants: small (low birth weight less than 10 centile for gestational age), preterm (gestational age less than 37 weeks) and full term. The total population of this study consisted of 12 children (4 subjects for each group). The purpose of the study was to examine phonetic and lexical development in these three populations to determine both normal and delayed patterns of this development over the second year of life. The time sampled for early behaviors were 18, 19, 20, and 21 months, based on chronological age. The spontaneous verbal productions of the subjects were tape-recorded and transcribed using phonetic symbols (IPA). Comparison were made between preterm and full term infants based on both chronological and gestational age. The data resulting from the comparison of our subjects on these parameters provide us with evidence that there can be early indicators of later speech and lexical development of the group of preterm infants.
小样儿（出生体重低于孕周的第10百分位数）、早产儿（孕周小于37周）和足月儿。该研究的总样本包括12名儿童（每组4名受试者）。该研究的目的是考察这三组人群的语音和词汇发展情况，以确定在生命的第二年中这种发展的正常模式和延迟模式。根据实际年龄，早期行为的采样时间为18、19、20和21个月。受试者的自发言语产出被录音，并使用音标（国际音标）进行转录。基于实际年龄和孕周，对早产儿和足月儿进行了比较。我们的受试者在这些参数上比较所得的数据为我们提供了证据，表明早产儿组后期言语和词汇发展可能存在早期指标。
