Premature infants are at risk for a variety of developmental problems including delays in language development, perceptual processing and social interaction. The goal of this mentored research is to examine the development of interactive communication in preterm infants so that interventions can be designed to improve their abilities. The educational aims of the research are to refine skills in observing interactive communications, including behavioral coding of discrete qualities of communication and sequential analysis of social interaction, and to develop a coding schema for future intervention research. The purpose of the study is to observe interactions between premature infants and their mothers to describe patterns of communication over the first 4 months of life, and to compare their interactive communication abilities to those of term infants and their mothers. The sample will include 20 preterm infant-mother pairs and 20 full term infant-mother pairs. One hour videotaped observations will be made on three occasions for the preterm group (36 weeks gestation, 41 weeks corrected age, and at 4 months corrected age) and on 2 occasions for the term group (at 1 week and 4 months of age). The aims are to describe the development of vocal and nonvocal exchanges in premature infants, determine the effect of neurological insults and gestation on these patterns, and to compare preterm and term infant patterns of interactive communication. Observational behavioral coding will be used to determine the quality, frequency, duration and sequence of vocal and non vocal behavior of mothers and infants. Sequential analysis of the observed interactions will be conducted and conditional and transitional probabilities calculated. The two groups will be compared with repeated measures MANOVA and the mixed general linear model on selected behavioral responses and vocalizations.

早产儿面临各种发育问题的风险，包括语言发育、知觉处理和社交互动的延迟。 这项指导研究的目标是检查早产儿互动交流的发展情况，以便设计干预措施来提高他们的能力。 该研究的教育目的是提高观察互动交流的技能，包括交流离散质量的行为编码和社会互动的顺序分析，并为未来的干预研究开发编码模式。该研究的目的是观察早产儿与其母亲之间的互动，以描述生命前 4 个月的沟通模式，并将他们与足月婴儿及其母亲的互动沟通能力进行比较。 该样本将包括 20 对早产婴儿-母亲和 20 对足月婴儿-母亲。 早产组（妊娠 36 周、校正周龄 41 周、校正月龄）进行 3 次 1 小时的录像观察，足月组（1 周龄和 4 个月龄）进行 2 次 1 小时的录像观察。 目的是描述早产儿声音和非声音交流的发展，确定神经损伤和妊娠对这些模式的影响，并比较早产儿和足月婴儿的互动交流模式。 观察行为编码将用于确定母亲和婴儿的声音和非声音行为的质量、频率、持续时间和顺序。 将对观察到的相互作用进行顺序分析，并计算条件概率和转移概率。 将通过重复测量多元方差分析和混合一般线性模型对选定的行为反应和发声进行比较。
