Abstract
C. P. Richter and K. H. Campbell (1940b) originally defined taste threshold as "the point at which the rats first indicated that they recognized a difference between the distilled water and the solutions" (p. 34). The present study sought to apply this simple behavioral measure to the investigation of strain differences in taste sensitivities, particularly with respect to predictive relationships in ethanol, saccharin, and quinine preference. Fawn-Hooded, Lewis, and Wistar rats were presented with gradual increments in concentration of ethanol (0.01-15%; C. P. Richter & K. H. Campbell, 1940a), saccharin (0.002-3%) or quinine (0.0001-0.0055). Results showed that although intake for saccharin was similar in all strains, consumption of ethanol and quinine differed among the groups. Although previous research has proposed that sweet preference is a promising behavioral marker for ethanol preference, these results suggested that bitter preference may be a more reliable predictor of ethanol preference in rats.

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
