Abstract
The experiments reported here evaluated the hypothesis that an amphetamine-paired flavor elicits conditioned fear-arousal, whereas a lithium-paired flavor elicits conditioned nausea-disgust by examining the effect of prior flavor exposure on an acoustic startle reaction (ASR). Exposure to a lithium-paired flavor by intraoral infusion, either immediately prior to a startle session (Experiment 1) or during a startle session (Experiments 2 and 3), resulted in a blunted ASR. In contrast, intraoral infusion of an amphetamine-paired flavor resulted in a potentiated ASR. The blunted ASR produced by exposure to a lithium-paired flavor dramatically reversed to a potentiated ASR when rats were pretreated with the antiemetic drug ondansetron prior to the saccharin-lithium pairing (Experiment 3). The findings shed light on a mechanism by which rewarding drugs produce conditioned taste avoidance in rats.

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
