Abstract
Memory for paired-associate words is facilitated by interim testing relative to restudy. According to the mediator effectiveness hypothesis, the benefit of retrieval practice is a consequence of the activation of a mediator word linking the cue and target. Evidence for the activation of cue-related mediators stems from the finding that mediators are more effective at prompting recall of target words than are words not associated with the original cue, a pattern that is larger following testing than restudy. The benefit of testing for the unstudied cues at the final test is referred to as transfer of test-enhanced learning. One goal of the current study was to examine whether the activation of mediators leads to the recall of targets indirectly via the original cues in a process known as backward chaining. We indexed backward chaining with the probability of incorrectly recalling a trial-specific original cue in place of a target. The second goal was to explore whether testing would yield a transfer effect for cues associated with target words. In four experiments, following an initial study of weakly related word pairs (e.g., Mother-CHILD), participants either restudied the pairs or attempted to recall the target given the original cue (e.g., Mother). On a final cued-recall test, participants were presented with unstudied cues that were related to either the original cue (semantic mediators, e.g., Father) or the target (target-related cues, e.g., Baby). The type of new cue presented on the final test was varied either between subjects (Experiment 1) or mixed within a list (Experiments 2, 3, and 4). Mixing mediators and target-related cues reduced the transfer of test-enhanced learning and increased the likelihood of recalling the original cues when shown a mediator. These results challenge the assumptions of the mediator effectiveness hypothesis.

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.
