A Methodology to Explore Empirical Evidence for a Macro Cognitive Architecture of Expertise
Bibliographic record
Abstract
The thesis investigated if the SGOMS architecture is the default structure for processing expert knowledge.We compared an SGOMS model implemented in ACT-R to a model using ACT-R alone.The task had no interruptions but the SGOMS/ACT-R model had processes to deal with interruptions.As result, the SGOMS/ACT-R model predicted slower processing times than the ACT-R alone model, which did not have these extra processes.The task was a well-practiced memory game.The results showed that, although the perceptual motor strategies of the two participants were very different, their cognitive processing for most of the task was virtually identical and in line with the SGOMS predictions.Overall, the results suggest that people use the SGOMS mechanisms by default but can deliberately train themselves to avoid some SGOMS mechanisms for at least some parts of the task.iii

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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, unvalidatedLabeled directly by 2 models reading the full record.
