Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

Usage-based theory has proposed that learning of linguistic constructions is facilitated by input that contains few high-frequency exemplars, in what is known as a skewed (or Zipfian) input distribution. Early empirical work provided support to this idea, but subsequent L2 research has provided mixed findings. However, previous approaches have not…

A growing consensus sees the bilingual lexicon as an integrated, nonselective system. However, the way bilingual experience shapes the architecture and functioning of the lexicon is not well understood. This study investigates bilingual lexical-semantic representation and processing employing written translation priming. We focus on the role of…

The congruency effect--that is, faster and more accurate processing of congruent multiword units, has been demonstrated in multiple studies. It is still unclear, however, what its underlying mechanism is, and how congruency may interact with other factors. Using an acceptability judgement task, this study examined the congruency effect in…

Usage-based theories hold that mental representation of language is shaped by a lifetime of usage. Both input to which first language (L1) and second language (L2) users are exposed and their own language production affect their construction learning and entrenchment. The present study investigates L2 users' knowledge of two…

This study is a replication and extension of Morgan-Short et al.'s (2018) investigation into the role of attention in input processing by L1-Polish learners of L2-Spanish, with proficiency and language of assessment explored as two key methodological factors. Our aims were twofold: to investigate learners' comprehension in different conditions…

This article reports on a study exploring the differential effects of immediate and delayed corrective feedback (CF) on the acquisition of the English past tense. One hundred and forty-five seventh-grade EFL learners were assigned to four groups: Immediate CF, Delayed CF, Task Only, and Control. Each experimental group performed six focused…

Although retrieval of lexical forms is a prerequisite for language production, research of L2 vocabulary learning has focused much more on meanings and form-meaning mappings than on development of detailed, accessible mental representations of forms. This is particularly true with respect to multi-word items (MWIs). We report an experimental study…

Sixty target words were selected from two sets of graded readers. One set contained three readers with the same title, "The Railway Children," and the other set, three books about Sherlock Holmes. Students chose one of the two sets to read and were given a pretest, an immediate posttest, and a five-week delayed posttest on their…

Based on writing produced by second language learners at different proficiency levels (CEFR A1 to C1), we adopted a usage-based approach (Ellis, Römer, & O'Donnell, 2016; Tyler & Ortega, 2018) to investigate how German and Spanish learner knowledge of 19 English verb-argument constructions (VACs; e.g., "V with n," illustrated by…

This study investigated the effectiveness of providing L1 explicit information (EI) with practice for making more accurate and faster interpretations of L2 French "Imparfait" (IMP). Two treatments were investigated: (a) "L2-only," providing EI about the L2 with L2 interpretation practice, and (b) "L2+L1," providing…

This paper presents an experimental study of the rarely explored question of how input through instruction interacts with L2 acquisition at the level of modular linguistic knowledge. The investigation focuses on L2 knowledge of the English polarity item "any," whose properties are only partially covered by typical language-teaching…

Linguistic analyses suggest that the nongeneric use of the English definite article "the" falls into four major categories: cultural, situation, structural, and textual. Aims to determine whether these uses present different levels of difficulty for English-as-a-Second-Language students and whether they are acquired at the same time. (Author/VWL)

Using frequency findings from corpus linguistics, explores the relationship between the information presented in English-as-a-Second/Foreign-Language (ESL/EFL) materials and what is known about actual language use based on empirical studies. Three aspects of materials development for grammar instruction are discussed. (Author/VWL)

Demonstrates how nonnative varieties of English are distinct from interlanguages or approximate systems of "established" varieties of English. Two strategies are examined: (1) the generalization of rules found in the established varieties of English and (2) the transfer into English of linguistic features from learners' other languages.…
