DEVELOPMENT OF COMMUNICATION IN PRETERM INFANTS

早产儿面临着各种发育问题的风险，包括语言发展、感知处理和社会互动方面的延迟。这项指导研究的目的是检查早产儿互动沟通的发展，以便可以设计干预措施来提高他们的能力。本研究的教育目的是提高观察互动沟通的技巧，包括对离散沟通品质的行为编码和对社会互动的顺序分析，并为未来的干预研究开发编码模式。本研究的目的是观察早产儿与母亲之间的互动，以描述出生后4个月的交流模式，并将其与足月婴儿及其母亲的互动交流能力进行比较。样本将包括20对早产儿-母亲和20对足月婴儿-母亲。对早产儿组（妊娠36周、矫正年龄41周和矫正年龄4个月）进行3次1小时的录像观察，对足月组（1周和4个月）进行2次录像观察。目的是描述早产儿的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儿的互动交流模式。观察性行为编码将用于确定母亲和婴儿发声和非发声行为的质量、频率、持续时间和顺序。将对观测到的相互作用进行顺序分析，并计算条件概率和过渡概率。两组将通过重复测量方差分析和混合一般线性模型对选择的行为反应和发声进行比较。

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.
