Abstract
A visual search task was used to investigate how visual attention and intraindividual variability changes with mild cognitive impairment (MCI). Specifically, we examined the contribution of shifting efficacy, distribution of attention, and controlled processing to declines in visual attention in two groups with MCI (single-domain amnestic and multi-domain amnestic), and measured changes in intraindividual variability. Our results demonstrate that visual search performance is attenuated in multi-domain amnestic MCI, but not single-domain amnestic MCI. In addition, we found that the multi-domain amnestic MCI group was more variable than the older controls and single-domain amnestic MCI participants. These between-group differences in search efficacy and intraindividual variability increased as a function of task complexity. We attribute these decrements in performance to changes in the control of attention and shifting efficacy, but not the distribution of attention.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
