Abstract
Constructional apraxia is impairment in activities such as building, assembling, and drawing. In this paper data is presented on the performance of left and right hemisphere single focal contiguous stroke lesion participants on drawing tasks of houses, trees, and persons. In this study, 41 participants completed a comprehensive neuropsychological battery including the House-Tree-Person Drawing Task. The drawings were then rated as exhibiting signs of neurological impairment or non-impairment by three evaluators that were blinded to the medical condition of the patient. The neuropsychological evaluator did not rate the drawings. There was 72% agreement between the three evaluators of the 123 drawings in their dichotomous ratings of constructional apraxia drawings. Both a group mean and case series analysis was used to examine the data and some patterns of concordance with a detailed cognitive neuropsychological model of constructional apraxia was found.

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
