Abstract Details

2023, Doctor of Philosophy, Ohio State University, Speech and Hearing Science.
Preterm infants are at increased risk for long-term neurodevelopmental sequelae affecting all areas of development. Despite ongoing advances in medical care resulting in infants surviving from increasingly younger gestational ages at birth, the neurodevelopmental implications of extreme prematurity and its requisite NICU stay are not yet fully understood. Furthermore, preterm infants are at increased risk for neural insults, further complicating their developmental progression. Parental involvement in the NICU is a known contributor to improved outcomes; however, barriers to parental presence and involvement often reduce parents’ ability to contribute to their infant’s care. One potential way for parents to contribute to their infant’s care, even if they cannot be present at bedside, is through parent voice recordings, and, particularly, through infant-directed language. However, very little is known about the acoustic properties of infant-directed language to preterm infants, namely infant-directed speech and singing, or how these infants respond to infant-directed auditory stimuli. This dissertation consists of 7 chapters examining infant-directed speech and singing with preterm infants and its potential as an early intervention. The first and second chapters provide a background on challenges associated with preterm birth and current approaches to care in the NICU. Chapter 3 provides the theoretical and neuroscientific basis for the use of infant-directed speech and singing as neurodevelopmental support for preterm infants in the NICU. Chapters 4-6 outline three experiments that sought to better understand how preterm birth affects infant-directed language with preterm infants and their mothers. Chapter 4 focuses on the acoustic features of infant-directed speech and singing of mothers of preterm infants recorded during the perinatal period and discusses those features in the context of well-established acoustic parameters of infant-directed language with term infants. Chapter 5 examines the cortical responses of the preterm infants to their mother’s voice recordings, and Chapter 6 investigates the attentional capacity of a particular subset of high-risk preterm infants, those with neural insults, in attending to their mother’s voice. Implications for these new understandings are discussed and future directions are provided.
