Abstract
In a cross-sectional study, we examined age-related differences in visuo-spatial ability associated with image rotation, using two variants of Piaget's 'Three-Mountain Task.' The object-mental rotation (OMR) task detects the ability to mentally rotate an image, whereas the subject-mental rotation (SMR) task reveals the ability to mentally change one's perspective. A group of 33 young adults, 26 middle-aged adults, and 31 elderly normal adults were studied. Both tasks revealed age-related differences in performance but a larger difference between middle-aged and elderly group was observed for SMR than OMR performance. Age-related increases in the 'egocentric' type of error were found only on the SMR task. The results suggest that the ability to mentally change one's perspective declines with age, perhaps more than the ability to mentally rotate objects.

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
