q3 i? After adjusting for pretest differences, there was no effect for group on the immediate oral imitation posttest, and no group difference on the immediate grammaticality judgment posttest. → Rod Ellis 2006

q3 · i? · causal · r1

ANCOVA on the oral imitation test immediate posttest for the three groups (n = 34). "no effect for group on the immediate posttest, F (2, 34) = 0.961, p = .394"; equivalence was not tested. The GJT immediate posttest was likewise nonsignificant (F = 0.714, p = .498).

"there is no effect for group on the immediate posttest, F (2, 34) = 0.961, p = .394; however, there is on the delayed posttest"

• Explicit metalinguistic feedback outperforms recasts on the delayed oral imitation posttest measuring implicit knowledge — related
• Metalinguistic feedback produced system learning, generalizing to verbs not included in the treatment — related
• Feedback effects on ungrammatical GJT items were weak because learners already possessed the relevant explicit knowledge — related
• Explicit metalinguistic feedback outperforms recasts on the delayed grammaticality judgment posttest — related
• Procedural memory predicts immediate regular-past-tense UGJT posttest scores, controlling for pretest, only under metalinguistic prompts — related
• Learners in all three corrective-feedback groups improve irregular past tense performance on both GJT and EIT from pretest to posttests, a within-group gain that does not separate the feedback types — related
• Declarative memory predicts immediate UGJT posttest gains for irregular past tense only under recasts — related
• Pretest scores significantly predict posttest scores across CF types and outcome measures — related
• Metalinguistic feedback outperforms recasts on the immediate post-test, but the two do not differ significantly on the delayed post-test — reports the opposite
