An experimental study on grammatical sensitivity and production competence in Chinese and Spanish EFL learners and its implications on EFL teaching methods.

Implicit knowledge acquired by L2 learners determines their language competence; however, it remains an issue to what extent advanced EFL learners can acquire implicit language knowledge. This study aims at finding out whether advanced EFL learners from two different L1s could acquire a level of implicit knowledge of English questions by using the modified Elicited Oral Imitation Task. A quantitative, experimental study with the Elicited Oral Imitation Task experimental tool was designed. A total number of 91 participants were recruited via the online experimental platform from October to November, 2021, distributed into a native speaker group, a Chinese EFL learner group, and a Spanish EFL group. The study evaluated participants' implicit language knowledge by assessing two indicators: the grammatical sensitivity index and the production index. Independent-sample t-test and one-way analysis of variance (ANOVA) were applied to examine the differences in the two indices among different groups. Results revealed that both EFL groups displayed a significant difference with the native speaker group in their degree of implicit knowledge of English questions in general. A further comparison of the two indicators showed that while both EFL groups displayed a relatively high grammatical sensitivity to morpho-syntactic errors in English questions, their corrective production rate of ungrammatical sentences was notably lower. These results indicate that advanced EFL learners had difficulty in acquiring implicit knowledge of English questions at native speaker' level. These findings also imply a gap between EFL learners' language knowledge level and corresponding language production competence. Targeting this gap within the Interaction-based production-oriented approach pedagogical implications based on were suggested for enhancing EFL learners' language production competence in EFL contexts.

Implicit Knowledge Acquisition and Potential Challenges for Advanced Chinese and Spanish EFL Learners: A Word Monitoring Test on English Questions.

This study aims to explore whether advanced EFL learners can acquire implicit knowledge of basic sentence structures, such as English questions. We ran a reaction-time experiment, a word monitoring test experiment to test learners' implicit knowledge by checking advanced EFL learners' grammatical sensitivity to English questions with five types of grammatical errors. The study recruited three groups of participants: native English speakers (n = 12), advanced Chinese EFL learners (n = 32), and advanced Spanish EFL learners (n = 37). Our results revealed that advanced EFL learners had not yet attained native-equivalent implicit grammar knowledge in English questions, despite their English proficiency level. The results also indicated that the learners' different L1 languages do not impact advanced learners' overall implicit knowledge acquisition but constitute influential factors for particular morphosyntactic inflections in English question formation.

Syntactic Priming As a Test of Argument Structure: A Self-paced Reading Experiment.

Using data from a behavioral structural priming experiment, we test two competing theoretical approaches to argument structure, which attribute different configurations to (in)transitive structures. These approaches make different claims about the relationship between unergatives and transitive structures selecting either a DP complement or a small clause complement in structurally unambiguous sentences, thus making different predictions about priming relations between them. Using statistical tools that combine a factorial 6 × 6 within subjects ANOVA, a mixed effects ANCOVA and a linear mixed effects regression model, we report syntactic priming effects in comprehension, which suggest a stronger predictive contribution of a model that supports an interpretive semantics view of syntax, whereby syntactic structures do not necessarily reflect argument/event structure in semantically unambiguous configurations. They also contribute novel experimental evidence that correlate representational complexity with language processing in the mind and brain. Our study further upholds the validity of combining quantitative methods and theoretical approaches to linguistics for advancing our knowledge of syntactic phenomena.
