Abstract

fetched live from OpenAlex

Human observers are more sensitive to faces than any other visual stimulus. For decades, researchers have been interested in determining the visual information contained within faces that make them “special”. Recent evidence suggests that the most important information in faces for recognition is contained within horizontally oriented frequency bands of the face image (Dakin & Watt, 2009), which suggests that a disproportionate amount of information processing comes from mechanisms that are horizontally tuned. If this is true, then adapting those mechanisms in an orientation-specific manner should influence our ability to process faces. In this research, we will evaluate whether or not orientation-specific adaptation influences face recognition. If face processing heavily depends upon horizontal information, then selectively adapting those mechanisms should reduce observers’ ability to recognize faces. The same effect should not be observed with vertical adaptation. Overall, these results will provide insights into the role that low-level orientation information plays in facial recognition.

Not 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.
