Abstract
Trout learned the operant task of pendulum-pressing for a food-reward in a mean of 4.3 sessions lasting 1 hr. In a separate phase, fish also learned--through classical conditioning--to associate a neutral light cue with an aversive stimulus. When again allowed to pendulum-press for food, after aversive classical conditioning, there was a drop in the rate of responding. The mean rate dropped from 3.6-2.9 responses per min. Most important, when the light-stimulus was superimposed on a steady bout of pendulum-pressing, trout ceased to press the pendulum and did not resume activity until termination of the light-stimulus (mean number of responses during a 3-min interval immediately prior to light-stimulus = 14.3 vs. during 3-min light-stimulus = 0.1). Psychologists have used this decrease in operant responding, or "conditioned emotional response," as a tool to examine the psychological nature of this type of aversive conditioning. In this study, the fish demonstrated various results under this paradigm similar to those shown by "higher" nonhuman animals, therefore challenging the view of fish as unconscious, nonsentient animals.

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
