Auditory Processing in Growth-Restricted Fetuses and Newborns and Later Language Development
Bibliographic record
Abstract
Growth-restricted fetuses and newborns are at increased risk for language deficits, and language impairments have been associated with increased risk for cognitive, social, emotional, and behavioral clinical disorders. Auditory-information processing was examined longitudinally in 167 fetuses in Study 1, 96 of whom were reexamined as newborns in Study 2. In Study 3, language was assessed at 15 months of age for 75 infants from Study 1. Compared with participants who were appropriately grown for gestational age, growth-restricted fetuses showed less sustained response to their mother’s voice; growth-restricted newborns showed less recovery to a novel word after habituation and no preference for their mother’s voice. At 15 months of age, those infants who had been born growth restricted showed expressive-language deficits on Mullen Scales of Early Learning and MacArthur-Bates Communicative Development Inventory subscales. Our results support the hypothesis that fetal growth restriction affects the development of auditory-system functioning and indicate that it may be possible to identify individual fetuses and newborns at risk for language deficits and to intervene early, when the foundation for language is being laid.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
