Abstract
Twelve Japanese infant-mother dyads were video-recorded at home in naturalistic interaction approximately every two weeks at varying ages between 9 and 14 months. Changes in their gestural repertoire that were similar to other groups studied previously were: an increase over sessions in Comment gestures, namely pointing but not showing, and a decrease in overall Request gestures, particularly reaching. Request gestures involving cognizance of agency increased, however. Increases in Object exchange gestures and decreases in Protest/Rejection and Emotive gestures found in previous studies were not replicated in this group. Agency gestures after 12 months were related to number of words understood, as reported on the JCDI. There was good agreement on the whole between gestures reported by mothers on the JCDI and the same gestures observed directly. These results provide some support for the universality of key gestural changes considered important for language acquisition.

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
