Characteristics of the developing human locomotor system: Similarities to other mammals
Bibliographic record
Abstract
Similarities in the development of locomotion between young children and other mammals are explored by reanalysis of data accrued over ~18 years. Supported stepping in children was tested on a treadmill. Although the time course of development is more protracted in humans compared to other mammals, the same trends are seen. For example, the duration of the stepping cycle shortens rapidly in the first 5 months of life. Hypermetric flexion of the hip and knee during stepping is seen in children <3 mo old. Stability of the locomotor rhythm both with respect to cycle duration within a limb and coupling between limbs improves slowly. Finally, coordination between the left and right legs can be manipulated with training, indicating experience-dependent learning at a young age. The possible reasons for these remarkably similar trends in development are explored as a function of maturational time tables for neural structures.

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.
