A parallel binding solution via separate integration and segregation mechanisms
Bibliographic record
Abstract
Intro. The visual system's modular structure raises the question of how cues, which are analyzed in separate modules / brain regions, are brought back together (the binding problem). Previous research has shown that contour binding across attributes occurs in parallel, within attribute maps, throughout the visual field, and with an initial “default” bias towards integration (Poirier & Frost, 1998–2002). Model. The default integration bias suggests that assemblies (and stimulus features) are integrated via fairly “automatic” facilitory connections, of low spatiotemporal resolutions. In addition, segregation occurs via “intelligent” inhibitory connections, focusing on local specific differences of higher contrast and information value. Binding is dynamic, flexible, uses multiple cues simultaneously, and propagates across assemblies and brain areas. In this model, binding influences tasks because: (1) integrated items are processed as one, reducing visual scene complexity, (2) segregated items “pop-out”, and (3) two different items erroneously bound together will share properties, leading to illusions and possibly difficult search. Implications. This theoretical framework requires re-interpretation of data for many tasks. (1) Visual search measures the efficiency with which a target segregates while distractors integrate together. (2) Redundancy effects measure a stimulus' ability to stimulate the integration mechanisms. (3) Illusory conjunctions are found when integration occurs but segregation fails, despite spatial separation of items. (4) Texture segregation differs from single item similarity judgments because the former also uses spatial effects like collinearity (integration) & edge detection (segregation). Discussion. The model provides a unifying framework that reconciles different results and research areas. Thus, a meta-analysis of several different tasks should reveal many specific integration & segregation cues, along with their spatiotemporal properties.

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.
