Concurrent Verbal‐Articulatory Load Attenuates Feedback‐Triggered Overt Morphosyntactic Repair in L2 Arabic

Corrective recasts provide a target form, but successful overt repair may depend on processing resources. We tested whether concurrent verbal‐articulatory load reduces feedback‐triggered morphosyntactic repair in 120 B1–B2 learners of Modern Standard Arabic. A 2 × 2 between‐participants experiment crossed recasts with articulatory suppression across 1440 eligible initial‐error trials spanning case marking, agreement and derived verb patterns. Observed repair after recasts was 75% without suppression and 35% with suppression, versus 10% and 5% without recasts. A multilevel Bernoulli‐logit model of non‐repair showed a Feedback × Suppression interaction ( β = 1.10, 95% CrI [0.45, 1.73]). Supplementary right‐censored lognormal modelling also indicated attenuation of the recast benefit (interaction time ratio = 1.61 [1.25, 2.07]), although 68.75% of trials lacked observed repair and the event‐time interpretation is assumption‐dependent. Uncued post‐tests and manipulation checks provided secondary evidence. Recasts facilitated overt correction, but their advantage diminished under concurrent load. The findings support resource‐sensitive interference, not an isolated phonological‐loop mechanism; a matched nonverbal control is required for process‐specific attribution.
