Contextual disambiguation of rotating Necker cubes
Bibliographic record
Abstract
Ambiguous figures perceptually alternate between different interpretations, and the particular interpretation is known to be affected by context. The aim of the study was to investigate the effect of an unambiguous rotating wire cube with various motion parameters on the perceived direction of an adjacent Necker cube continuously rotating at constant speed. The context figure parameters were rotation speed (same as, half, or twice the speed of the ambiguous figure) and rate of reversal (intervals between reversals 2s, 4s, and 8s). The two rotating figures were presented above and below fixation for 32s per trial. Observers indicated via key-press the direction of rotation of the ambiguous figure. Results show that the rate of ambiguous figure reversals was dependent on context, specifically reversal rates were correlated with those of the context figure. For some observers the correlation between reversal rates also depended on the similarity of speeds. These results suggest that changes in motion direction more than speed similarity binds ambiguous object motion to its unambiguous motion context. Meeting abstract presented at VSS 2014

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.
