Extensive research exists on the effects of task design features on measuring L2 learners’ implicit and explicit knowledge. However, the role of structure difficulty has received limited attention. Additionally, the use of fine-grained measures of implicit knowledge has remained underexplored. To address these gaps, utilizing objective criteria to select easy (plural -s) and difficult (third-person -s) structures, a total of 256 experimental items, equally divided into grammatical and ungrammatical, as well as easy and difficult structures, were developed and administered to 32 advanced L2 learners. A word monitoring task (WMT) assessed their implicit knowledge through reaction time (RT) and grammaticality sensitivity index (GSI), while a timed grammaticality judgment test (TGJT) measured their automatized explicit knowledge through accuracy scores. The WMT results showed longer RTs for ungrammatical items and larger GSI for the plural -s items, revealing participants’ more implicit knowledge of the easy structure. The results of the TGJT revealed that L2 learners judged grammatical items more accurately than ungrammatical ones and the plural -s items more accurately than third-person -s ones, showing participants’ more automatized explicit knowledge of the easy and grammatical structures. The findings highlight the influence of grammaticality and structure difficulty on knowledge retrieval and suggest that advanced L2 learners exhibit stronger implicit and automatized explicit knowledge of the easy structure. These findings underscore the need for tailored instructional approaches to address difficult structures and emphasize the importance of using real-time psycholinguistic measures to examine L2 learners’ implicit knowledge.

The neurolinguistic approach (NLA) nests the claim that both internal and external grammars (i.e., implicit and explicit grammar knowledge) develop through an intensive orality-based pedagogy. The present study put this claim to the test focusing on Iranian English language learners’ development of implicit and explicit knowledge of definite and indefinite English articles (EAs). Forty-three Iranian English language learners constituting 2 intact lower-intermediate classes were randomly assigned to a control group (CG; N = 20) and an experimental group (EG; N = 23). EG underwent four 1.5-hr project-based sessions of NLA-based instruction on definite and indefinite EAs. Each session began and ended with authentic oral practice of the structure under study. There was (a) a paragraph reading phase followed by rule induction and (b) a writing phase in between the two oral practice phases. CG was presented with reading texts (amply instantiating EAs), rule explanation, and communicative tasks. A timed grammaticality judgment test and an EA-focused oral proficiency interview were employed to estimate the participants’ implicit knowledge, and an untimed grammaticality judgment test and a metalinguistic knowledge test were deployed to measure their explicit knowledge. ANOVA results showed (a) EG’s development of implicit and explicit knowledge of EAs, but CG’s development of only explicit knowledge of EAs, and (b) EG’s significantly greater gain in both knowledge types. The findings reveal NLA’s potential for the development of both types of knowledge concerning definite and indefinite EAs, and have implications for the intensive instruction of knotty structures for low proficiency L2 learners.
