When less is more: Impact of face processing ability on recognition of visually degraded faces.
Bibliographic record
Abstract
It is generally thought that faces are perceived as indissociable wholes. As a result, many assume that hiding large portions of the face by the addition of noise or by masking limits or qualitatively alters natural "expert" face processing by forcing observers to use atypical processing mechanisms. We addressed this question by measuring face processing abilities with whole faces and with Bubbles (Gosselin & Schyns, 2001), an extreme masking method thought by some to bias the observers toward the use of atypical processing mechanisms by limiting the use of whole-face strategies. We obtained a strong and negative correlation between individual face processing ability and the number of bubbles (r = -.79), and this correlation remained strong even after controlling for general visual/cognitive processing ability (rpartial = -.72). In other words, the better someone is at processing faces, the fewer facial parts they need to accurately carry out this task. Thus, contrary to what many researchers assume, face processing mechanisms appear to be quite insensitive to the visual impoverishment of the face stimulus.

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.
