Abstract

fetched live from OpenAlex

<h4>PURPOSE</h4> <p>Motion-defined form deficits in the fellow eye and the amblyopic eye of children with amblyopia implicate possible direction-selective motion processing or static figure–ground segregation deficits. Deficient motion-defined form perception in the fellow eye of amblyopic children may not be fully accounted for by a general motion processing deficit. This study investigates the contribution of figure–ground segregation deficits to the motion-defined form perception deficits in amblyopia.</p> <h4>METHODS</h4> <p>Performances of 6 amblyopic children (5 anisometropic, 1 anisostrabismic) and 32 control children with normal vision were assessed on motion-defined form, texture-defined form, and global motion tasks.</p> <h4>RESULTS</h4> <p>Performance on motion-defined and texture-defined form tasks was significantly worse in amblyopic children than in control children. Performance on global motion tasks was not significantly different between the 2 groups.</p> <h4>CONCLUSION</h4> <p>Faulty figure–ground segregation mechanisms are likely responsible for the observed motion-defined form perception deficits in amblyopia.</p> <p><cite>J Pediatr Ophthalmol Strabismus</cite> 2007;44:363-371.</p> <h4>AUTHORS</h4> <p>Ms. Wang and Dr. Giaschi are from the Department of Ophthalmology and Visual Sciences, University of British Columbia, Children’s and Women’s Health Centre of British Columbia, Vancouver, British Columbia, Canada.

Full frame distilled prediction

Teacher imitation

Not 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.
