Very few studies have investigated second language (L2) knowledge of word parts. The present study was set to measure L2 recognition of 35 English prefixes and the factors that might predict scores. The form and meaning sections of Sasao and Webb's Word Part Levels Test were administered to 152 Arabic learners of English as a foreign language…

Evidence of sensitivity to graphotactic and morphological patterns in English spelling has been extensively examined in monolinguals. Comparatively few studies have examined bilinguals' sensitivity to spelling regularities. The present study compared late Chinese-English bilinguals and English monolinguals on their sensitivity to systematic…

In this study, neural representation of adult second language (L2) speakers' implicit grammatical knowledge was investigated. Advanced L2 speakers of Japanese living in Japan, as well as L1 Japanese speakers, performed a word-monitoring task (proposed as an implicit knowledge test) in the MRI scanner. Behavioral measures were obtained from…

Learning new languages is a complex task involving both explicit and implicit processes (i.e., that do/do not involve awareness). Understanding how these processes interact is essential to a full account of second language (L2) learning, but accounts vary as to whether explicit processes help (e.g., DeKeyser, 2007), hinder (e.g., Ellis &…

The present study sets out to measure Turkish EFL learners' receptive affix knowledge and productive derivative vocabulary knowledge. More specifically, the extent to which Turkish EFL learners recognize written form of affixes, know the meaning of affixes and determine the part of speech of the derivatives produced by means of affixes and how…

Strong correlations between vocabulary and grammar are well attested in language development in monolingual and bilingual children. What is less clear is whether there is any directionality in the relationship between the two constructs, whether it is predictive over time, and the extent to which it is affected by language input. In the present…

In this study, we investigated crosslinguistic influence (CLI) at developmental stages of third language (L3) acquisition of English by Russian--Norwegian children (N = 31). We tested seven linguistic properties within three linguistic modules (morphology, syntax and syntax-semantics). We compared the L3 learners to Norwegian (N = 90) and Russian…

This study attempts to explain a systematic phenomenon that has been described in interlanguage grammars crosslinguistically: Null-Prep, which consists of omitting the obligatory preposition in certain movement constructions. We propose that Null-Prep is not related to lack of knowledge of "wh"-movement, as previously assumed, but to…

Nonverbal behavior can impact language proficiency scores in speaking tests, but there is little empirical information of the size or consistency of its effects or whether language proficiency may be a moderating variable. In this study, 100 novice raters watched and scored 30 recordings of test takers taking an international, high stakes…

Despite extensive use of online language learning during the pandemic of COVID, there is insufficient research on what factors influence students' foreign language achievements in online learning conditions. This article investigated the roles of language aptitude and online self-regulated learning in foreign language achievement in mainland…

We examine the second language (L2) acquisition of variable Spanish word order by first language (L1) speakers of English via the acquisition of unaccusative and transitive predicates in various focus-related contexts. We employ two bimodal linguistic tasks: (1) acceptability judgment task (B-AJT) and (2) appropriateness preference task (B-APT).…

Research consistently shows that adults engaged in tutored acquisition benefit from explicit instruction in several linguistic domains. For preschool children, it is often assumed that such explicit instruction does not make a difference. In the present study, we investigated whether explicit instruction affected young learners in acquiring a…

While formal L3 morphosyntactic acquisition research has focused on the roles of the L1 versus L2 during the L3 initial stages, we examine their roles during development. Specifically, we explore whether the L3 (here, Portuguese) revision process after non-facilitative transfer differs whether the initial L3 representation reflects the L1 or L2.…

This study examines the variable occurrence of preposition duplication in contexts of coordination in Spanish (e.g., "Fui con mi madre y (con) mi padre"). We build on previous research on this variable morphosyntactic phenomenon (namely, prepositions in contexts of coordination) by expanding the type of data and the independent variables…

Advances in machine learning (ML) are poised to contribute to our understanding of the linguistic processes associated with successful reading comprehension, which is a critical aspect of children's educational success. We used ML techniques to investigate and compare associations between children's reading comprehension and 260 linguistic…
