Abstract
This study deals with execution of drawings composed of embedded geometric shapes. Previous studies conducted by Baldy, Chatillon and Cadopi (1993) provided evidence for the existence of two executions : centripetal (outside to inside direction) and centrifugal (inside to outside direction). In these studies, it also appeared that, most of the time, the centripetal execution was produced. Our research focuses on its stability. Two series of experiments were carried out with children and adults. In the first one, participants copy several drawings. In the second one, the procedure we used is based on the theory of non linear dynamic systems. Indeed, participants have to reproduce a drawing by completing a continuum of circles which diameter gradually varies. The main results were the following. First, we confirm the effet of pattern structure on the execution ordre (Baldy, Chatillon & Magnan, 2001 ; van Sommers, 1984 ; Marot & Vinter, 2003). Second, we observe that the execution is influenced by previous execution(s), especially for young children. The centrifugal execution appears as stable as the centripetal execution since it resists to contextual contraints. This research underlines the relevance of using a dynamic approach to account of both within-individual variability and the cognitive development.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
