Interactive processes in an instance model of memory: A computational analysis of Jacoby’s (1983) dissociation between perception and recognition.
Bibliographic record
Abstract
In a classic and well-cited work, Jacoby (1983) demonstrated an important dissociation in which conceptual processing at study resulted in high performance on a standard memory test but low performance on a perceptual test. Perceptual processing at study resulted in the opposite pattern. I simulated the dissociation in MINERVA2, a classic instance model of memory. I assumed that stimulus representations are composed of perceptual and contextual features and that different study tasks favor the encoding of some features over others. I also assumed that different test tasks utilize some features more than others. The model successfully produced the dissociation. The simulations provide a formal account of a core principle of memory: Performance is determined by the appropriateness of processing at encoding given the demands of retrieval. In conjunction with previous work, I conclude that the result emerged from the same mechanisms that underlie empirical regularities from other areas of memory research (e.g., the production effect) and argue in favor of incorporating converging evidence across multiple modelling frameworks to provide stronger theoretical foundations.

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.
