An Investigation of Impulsivity in Children With Early-Treated Congenital Hypothyroidism
Bibliographic record
Abstract
The main feature of congenital hypothyroidism (CH) is a total or partial absence of thyroid hormone, caused by a developmental disorder of the thyroid gland. Introduction of neonatal thyroid screening allows early treatment with replacement hormone. As a result the prognosis of CH has greatly improved but neuropsychological problems do still occur. Claims that early-treated CH is associated with impulsivity were tested with a memory search task comprising 2 response probability conditions: a baseline condition in which "yes" and "no" responses were equally probable and a response bias condition in which the probability of a "no" response was raised to 70%. Impulsivity was defined as the ability to stop and change a response set and was assessed from the amount of inaccurate "no" responses made. Comparisons were made between 47 children with early-treated CH and 35 controls at the age of 7.5 years. Children with early-treated CH were notably slow and variable in their overall task performance but, most important, did not show signs of poor impulse control. Suggested short-term memory problems in these children could not be confirmed. Performance could not be attributed to early disease-related factors or lowered intelligence.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
