Using matrix training to promote recombinative generalization by children on the autism spectrum in China
Bibliographic record
Abstract
We implemented tact matrix training to teach tacts of spatial locations to four children (male, 4-7 years of age) on the autism spectrum in China. The experimental design involved a multiple-probe design across participants with pre- and postinstruction probes on untaught tacts and listener responses. Learning outcomes included taught tacts of object-preposition combinations, generalization of untaught tacts, and derived listener responses to all combinations in the matrix. All four participants acquired taught tacts after matrix training. Untaught tacts and listener responses were demonstrated with direct teaching, indicating the occurrence of recombinative generalization. Two participants maintained these skills with high accuracy for 4 or 8 weeks. The remaining two participants demonstrated high accuracy in untaught tacts and listener responses immediately after instruction; however, accuracy in taught and untaught tacts declined during the 4- or 8-week maintenance probes, whereas listener responses remained stable.

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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
