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…

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…

Recent studies suggest that developing L2 receptive knowledge of single words is associated with increased receptive knowledge of collocations. However, no study to date has directly examined the interrelationship between productive word knowledge and productive collocation knowledge. To address this gap, the present study administered a…

Little is known about how nonnative speakers process novel language patterns in the input they encounter. The present study examines whether nonnatives develop a sensitivity to novel binomials and their ordering preference from context. Thirty-nine nonnative speakers of English (L1 Arabic) read three short stories seeded with existing binomials…

This longitudinal study explored the roles of item- and learner-related variables in L2 learners' development of productive collocation knowledge (L1 = Dutch; L2 = German; NLearners= 50). Learners' form recall knowledge of 35 target collocations was measured three times over a 3-year period. The item-related variables investigated were L1-L2…

Research investigating incidental vocabulary learning through listening to songs has primarily relied on participants' self-report surveys on listening behaviors and its relationship with their vocabulary knowledge (Kuppens, 2010). Only one experimental study has investigated vocabulary learning gains from listening to songs (Medina, 1993). From…

A second language can be learned inside and outside the classroom. In this study we investigated the English and French vocabulary knowledge of 110 Dutch-speaking children (age 10-12), who received 100 hours of instruction in French, whereas their contact with English came from out-of-school exposure only. We examined the role of individual…

Academic lectures are potential sources of vocabulary learning for second language learners studying at universities where English is the medium of instruction, as well as those in English for Academic Purposes (EAP) programs. Topic-related vocabulary is likely to occur frequently in academic texts, and academic speech consists of a reasonable…

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…

A number of longitudinal studies of L2 production have reported frequency effects wherein learners' produce more frequent words as a function of time. The current study investigated the spoken output of English L2 learners over a four-month period of time using both native and non-native English speaker frequency norms for both word types and word…

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 effects of word frequency, collocational frequency, L1 congruency, and L2 proficiency, on L2 collocational processing. Two groups of L1 Japanese speakers of English (intermediate and advanced) and one group of English native speakers (NSs) performed an online acceptability judgment task on four types of adjective-noun…

Investigating the impact of linguistic characteristics on visual word recognition in children, we studied whether differences in native (L1) and second language (L2) processing already emerge at the beginning of reading development. German elementary school students in grades 2 to 6 completed a battery of standardized tests and a lexical decision…

This study examines frequency, contextual diversity, and contextual distinctiveness effects in predicting produced versus not-produced frequent nouns and verbs by early second language (L2) learners of English. The study analyzes whether word frequency is the strongest predictor of early L2 word production independent of contextual diversity and…
