Abstract
The present study examined the executive functions and spelling performance of children with developmental language disorder (DLD) over a school year. Through a fine-grained spelling error analysis, we investigated whether the measured executive functions would distinguish children's spelling profiles. The study comprised three groups: the DLD-S group (aged 7-9 years), including children with DLD matched on the total number of spelling errors produced on a dictation task with a typically developing group (n = 8); the DLD-AM group (aged 7-9 years), including children with DLD matched on chronological age and phonological awareness skills with the DLD-S group (n = 8); and the typically developing group (n = 16; aged 7-8 years). The results indicated that both DLD groups tended to produce more phonographic errors (i.e., spelling errors that change the phonology of the word) even if the DLD-S group produced a similar number of errors in comparison with the typically developing group. In particular, the DLD-AM group made more phoneme omissions than the other groups. The DLD-AM group also had the smallest spelling improvement over the school year and the weakest updating ability. In contrast, all groups had similar inhibition and cognitive flexibility abilities. This may indicate that some children with DLD present limitations in updating, which may lead to a slower spelling acquisition and a greater number of phonographic errors. Language impairments affect and delay spelling acquisition, and the presence of an updating deficit may exacerbate this delay.

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 it
