Abstract
Abstract Several investigators find that infants fail to use property information to individuate objects until 12 months of age (e.g., Xu & Carey, 1996), while others find that infants successfully employ property information in the service of object individuation at 9.5 months (e.g., Wilcox & Baillargeon, 1998a). This study investigated methodological differences between 2 sets of studies that may help to resolve this apparent conflict. It was hypothesized that infants younger than 12 months rely heavily on spatiotemporal information and it overrides any conflicting property information. In 2 experiments, we used a simplified manual search procedure much like Wilcox and Baillargeon's (1998a) simplified looking time procedure by reducing the number of alternations of the objects. Results suggest that when the spatiotemporal evidence specifying a single object that changes properties is weaker, 10-month-old infants succeed in using property information for object individuation.

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
