The Effect of Abnormal Intrauterine Thyroid Hormone Economies on Infant Cognitive Abilities
Bibliographic record
Abstract
OBJECTIVE: To evaluate how intrauterine and neonatal thyroid hormone deficiencies affect infant cognitive abilities. METHOD: 26 infants with intrauterine or neonatal thyroid hormone deficiency and 20 full-term infants with normal thyroid economies were studied at 6 months of age or corrected age. Reasons for thyroid hormone deficiency were maternal hypothyroidism, maternal hyperthyroidism treated with antithyroid medication, congenital hypothyroidism, and low-risk prematurity. A computer-generated task during which infants' eye-movements were videotaped was used to assess attention, memory, and learning abilities RESULTS: Data from transcribed videotapes showed the study group was significantly less attentive and had longer reaction times than controls but did not differ on indices of sustaining attention or learning. Within thyroid-deficient groups, offspring of treated hyperthyroid mothers showed an atypical profile suggestive of hypervigilance. CONCLUSION: A decreased fetal or maternal thyroid hormone supply in pregnancy is associated with infants' poorer attention and altered rates of information processing.

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.
