Fetal growth restriction may impact auditory development, potentially leading to language deficits in infants. This study explores how prenatal auditory processing differs in growth-restricted fetuses, impacting future language skills.

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Speech and Hearing Science

Background:

  • Over 20 years of research links fetal growth restriction to infant language deficits.
  • Animal models suggest growth restriction may delay myelination or increase sensorineural thresholds, affecting fetal auditory perception.
  • Previous studies show fetuses can hear and respond to sounds, indicating auditory system development and environmental sound exposure before birth.

Purpose of the Study:

  • To investigate the hypothesis that fetal growth restriction impacts auditory system development.
  • To compare auditory information processing in growth-restricted fetuses versus healthy, appropriately-grown fetuses.
  • To explore the association between atypical prenatal speech perception and later language abilities.

Main Methods:

  • Systematic study of auditory function in growth-restricted human fetuses (not previously reported).
  • Comparison of auditory processing in growth-restricted fetuses with that of healthy, appropriately-grown fetuses.
  • Assessment of speech perception differences and their correlation with subsequent language development.

Main Results:

  • Fetal growth restriction is hypothesized to cause atypical auditory information processing.
  • Speech perception in growth-restricted fetuses is expected to differ from that in normally grown fetuses.
  • These prenatal differences are anticipated to correlate with later language abilities.

Conclusions:

  • Prenatal auditory system development is crucial for language acquisition.
  • Fetal growth restriction may disrupt the foundation for language development by altering auditory processing.
  • Further research is needed to confirm the link between fetal auditory function and language outcomes.
