DEVELOPMENT OF COMMUNICATION IN PRETERM INFANTS

早产儿面临各种发育问题的风险，包括语言发育、知觉处理和社会互动方面的延迟。这项有指导的研究的目标是检查早产儿互动交流的发展，以便设计干预措施来提高他们的能力。这项研究的教育目的是提炼观察互动沟通的技能，包括对离散沟通质量的行为编码和对社交互动的顺序分析，并为未来的干预研究开发编码方案。本研究的目的是观察早产儿与母亲之间的互动，描述他们在出生后4个月内的交流模式，并将他们的互动交流能力与足月儿及其母亲的交流能力进行比较。样本将包括20对早产儿-母亲和20对足月婴儿-母亲。对早产儿组进行3次(36周妊娠、41周矫正年龄和4个月矫正年龄)的1小时录像观察，对足月儿组进行2次观察(1周和4个月龄)。其目的是描述早产儿发声和非发声交流的发展，确定神经侮辱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。将对观察到的相互作用进行顺序分析，并计算条件概率和过渡概率。这两组人将在选定的行为反应和发声方面与重复测量Manova和混合一般线性模型进行比较。

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.
