Abstract
ABSTRACT Although a relationship between morphological awareness and vocabulary has been widely observed, questions remain about the direction of that relationship. This longitudinal study explores the temporal relationship between morphological awareness and vocabulary among monolingual English-speaking children. Participants were 100 children tested in Grades 2 and 3. We evaluated morphological awareness and vocabulary in both grades, along with phonological awareness, word reading, pseudoword reading, and nonverbal reasoning. Cross-lagged regression analyses with autoregressive controls assessed the temporal relationship between morphological awareness and vocabulary; morphological awareness at Grade 2 predicted change in vocabulary between Grades 2 and 3, but vocabulary did not predict change in morphological awareness. The results add to our understanding of the relationship between these two developing skills.

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
