Abstract

fetched live from OpenAlex

Congruent contexts often facilitate performance in visual search and categorisation tasks using natural scenes. A congruent context is thought to contain predictive information about the types of objects likely to be encountered, as well as their location. However, in change detection tasks, changes embedded in congruent contexts often produce impaired performance relative to incongruent contexts. Using a stimulus set controlled for object perceptual salience, we compare performance across change detection and visual search tasks, as well as a hybrid of these 2 tasks. The results support a dual process account with opposing influences of context congruency on change detection and object identification processes, which contribute differentially to performance in visual search and change detection tasks.

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.
