What went where? Impaired object‐location learning in patients with right hippocampal lesions
Bibliographic record
Abstract
The role of the right medial temporal-lobe structures in memory for object location was investigated in three studies. In the first two studies, 118 patients with selective amygdalo-hippocampectomy or with anterior temporal lobectomy (either invading or largely sparing the hippocampal region) and 33 healthy participants were tested on array learning. Groups with extensive right hippocampal lesions were impaired on immediate and delayed recall and on learning to criterion. In the third study, magnetic resonance imaging (MRI) was used in 75 of these patients to measure the extent of tissue remaining in the various medial temporal-lobe structures. The extent of right hippocampus remaining was found to be the best predictor of array-learning performance, underlining its critical role in building a representation of objects in space.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
