Subclaims¶

q2 i? Among learners receiving recasts, declarative memory (LLAMA_B) significantly predicted immediate UGJT posttest scores for irregular past tense forms (β = .38, p = .03), but was not a significant predictor in the explicit correction or metalinguistic prompt groups. → Yusuke Sato 2023

q2 · i? · causal · r1

Multiple regression analyses for the irregular past tense UGJT across the same three classroom CF groups, with pretest as covariate. LLAMA_B was significant only for the recast group's immediate posttest (β = .38, p = .03, adjusted R² = .12); the article reports it was "significantly related only to the UGJT immediate posttest scores of the recast group."

"Declarative memory (LLAMA_B) scores were significantly related only to the UGJT immediate posttest scores of the recast group."

Discussion¶

Learner Variables¶

• Long-Term Memory — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Corrective feedback on second-language errors has a significant effect on L2 development that is maintained on delayed tests — the general claim this finding bears on, with the studies behind it
• Declarative memory shows no association with regular past tense learning under any CF type — related
• Procedural memory shows no association with irregular past tense learning under any CF type — related
• Pretest scores significantly predict posttest scores across CF types and outcome measures — related
• The literature is supportive of recasts, but recast effectiveness varies with the language area and learner knowledge, focus, and aptitudes — a broader claim this one bears on
• No group differences on immediate posttests for either feedback type on either measure — related
• Procedural memory predicts immediate regular-past-tense UGJT posttest scores, controlling for pretest, only under metalinguistic prompts — related
• Laboratory and classroom studies assess the effects of recasts and different CF types differentially — related
