Abstract
Previous studies of left visuospatial neglect using temporal order judgments (TOJs) have reported a temporal advantage for a stimulus presented on the right of fixation. The present case study examines an individual who shows a left temporal advantage on TOJ tasks, despite classic left-sided neglect on other tasks and in self-report. Experiment 1 found a continued left advantage on TOJs when employing a novel red/blue TOJ task to reduce potential response bias. Phasic alerting tones presented prior to random trials in Experiment 2 did not improve the abnormal attentional bias, as has been reported in previous studies of neglect. The addition of unilateral trials mixed within bilateral trials in Experiment 3 reduced the observed left advantage, suggesting a flexible attentional focus and implicating a role for strategic endogenous attentional strategies in this individual. Some implications for our understanding of endogenous orienting and relevance to rehabilitation therapy are discussed.

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
