Abstract
Infants may recognize facial expressions of emotion more readily when familiar faces express the emotions. Studies 1 and 2 investigated whether familiarity influences two metrics of emotion processing: Categorization and spontaneous preference. In Study 1 (n = 32), we replicated previous findings showing an asymmetrical pattern of categorization of happy and fearful faces in 6.5-month-old infants, and extended these findings by demonstrating that infants' categorization did not differ when emotions were expressed by familiar (i.e., caregiver) faces. In Study 2 (n = 34), we replicated the spontaneous preference for fearful over happy expressions in 6.5-month-old infants, and extended these findings by demonstrating that the spontaneous preference for fear was also present for familiar faces. Thus, infants' performance on two metrics of emotion processing did not differ depending on face familiarity.

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
