ABSTRACTThe English second language development of 19 children (mean age at outset = 5 years, 4 months) from various first language backgrounds was examined every 6 months for 2 years, using spontaneous language sampling, parental questionnaires, and a standardized receptive vocabulary test. Results showed that the children's mean mental age equivalency and standard scores on the Peabody Picture Vocabulary Test—Third Edition nearly met native-speaker expectations after an average of 34 months of exposure to English, a faster rate of development than has been reported in some other research. Children displayed the phenomenon of general all-purpose verbs through overextension of the semantically flexible verb do, an indicator of having to stretch their lexical resources for the communicative context. Regarding sources of individual differences, older age of second language onset and higher levels of mother's education were associated with faster growth in children's English lexical development, and nonverbal intelligence showed some limited influence on vocabulary outcomes; however, English use in the home had no consistent effects on vocabulary development.

Vocabulary learning has been traditionally considered central to second language learning. It may take place either intentionally, by means of deliberate attempts to commit factual information to memory, or incidentally, as a consequence of other cognitive processes involving comprehension. Video games, which have been extensively employed in educational contexts to understand lexical development in foreign languages, foster both exposure to and the production of authentic and meaning-focused vocabulary. An empirical study was conducted to explore the effect of playing an online multiplayer social deduction game (i.e., a game in which players attempt to uncover each other’s hidden role) on incidental and intentional second language (L2) vocabulary learning. Secondary school pre-intermediate English as a Foreign Language (EFL) students (n = 54) took a vocabulary pre-test that identified eight unknown words likely to appear in the video game Among Us. Then, students were randomly assigned to different groups of players and to different learning conditions—within each group, half of the players were given a list of phrases containing such target words, which they were encouraged to meaningfully use in the game by means of written interaction. In doing so, students learnt some target words intentionally and provided contextualized incidental exposure to other players. They took a vocabulary test after two sessions of practice with the game to explore intentional and incidental L2 vocabulary learning gains. The pre- and post-tests suggested, among other results, that players using new L2 words in the game Among Us would retain more vocabulary than players only encountering them, that vocabulary intentionally input helped other users trigger incidental vocabulary learning, and that repetition had a positive effect on L2 vocabulary learning.

In the 12 years since Studies in Second Language Acquisition published its first thematic collection on L2 lexical issues, “The use and acquisition of the second language lexicon,” edited by S. Gass (1987), the centrality of lexical development in second language acquisition has received ever increasing recognition from researchers (see, for example, volumes by Arnaud & Béjoint, 1992; Coady & Huckin, 1997; Haastrup, 1991; Haastrup & Viberg, 1998; Harley, 1995, 1996; Hatch & Brown, 1995; Huckin, Haynes, & Coady, 1993; Meara, 1992; Nation, 1990; Schmitt & McCarthy, 1997; Schreuder & Weltens, 1993; Tréville, 1993; Tréville & Duquette, 1996). The 1987 collection was a leading foray into new territory, following a period of relative neglect of the lexicon in SLA. The issues taken up by its authors were quite diverse, ranging from the organization and components of the L2 lexicon, to aspects of acquisition such as cross-linguistic influence, restructuring, and rate, to L2 lexical-use issues such as retrieval and access. Since that time, a large body of L2 research and theory has developed around these and other topics, and it has become possible to deal comprehensively with single core issues in L2 lexical acquisition from multiple perspectives. The current collection is one such attempt, offering a set of related papers on the topic of incidental L2 vocabulary acquisition. Unlike the 1987 collection, which argued for recognition of the importance of the lexicon in a field dominantly concerned with the acquisition of syntax, the authors of the present collection assume the central importance of lexical acquisition.

This study charts the lexical development of three sequential bilingual kindergarteners whose first language, Romanian, was acquired naturalistically at home, and whose second language, English, was acquired in kindergarten. The children’s lexical development in English and Romanian was assessed at five different points over a two-year period via the PPVT-4 (peabody picture vocabulary test 4) and a specially adapted PPVT-4 for Romanian. The children’s lexical repertoires were further analyzed to uncover home versus school and cognate versus non-cognate acquisitional differences. In addition, because there is no database of lexical items acquired by monolingual Romanian children, the PPVT-4 adapted for Romanian was administered to 22 monolingual six-year-old Romanian children in Sibiu, Romania. The findings indicate the following: (i) the three bilinguals’ receptive vocabulary in English was below average when they joined kindergarten, and at or above average two years later; (ii) their lexical growth in Romanian was steady; (iii) the bilinguals’ scores for words belonging to a home register reflected ceiling effects in English and Romanian (i.e., were very well known); (iv) academic words were known to an equal extent in English and Romanian, but scores were lower than for the home register; and (v) there was no definitive evidence of cognate facilitation. A comparison of the monolingual and bilingual Romanian repertoires reflects the following: (i) equally high scores for home items; (ii) differences in scores in the academic register in favour of the Romanian monolinguals; and (iii) important lifestyle and cultural differences between the groups. The Romanian children, for example, were more familiar than their Canadian counterparts with items related to home maintenance, such as șmirghăluiește (‘sanding’) and mistrie (‘trowel’), or items probably learned in school, such as foca (‘walrus’) and broască țestoasă (‘tortoise’).

This paper reports on an approximate or partial replication of a study by Salsbury, Crossley & McNamara (2011) that examined the longitudinal developmental of a number of core lexical features related to word imageability, concreteness, familiarity, and meaningfulness in a spoken corpus of English second language (L2) learners. Salsbury et al. found no developmental growth patterns for word familiarity but strong growth patterns for word concreteness, imageability, and meaningfulness as a function of time such that L2 learners began to produce more sophisticated words. Salsbury et al. were the first to formally identify this relation between English proficiency and lexical sophistication, and a large number of studies investigating lexical proficiency have cited this article as a foundational study. There were, however, a number of limitations to the Salsbury et al. (2011) study that make it appropriate for replication. First, the sample size was relatively small (six learners sampled six times over the course of a year). In addition, the study did not control for a number of factors important in L2 acquisition studies (e.g., age, proficiency level, gender) and used a statistical technique that averaged group means and did not properly account for individual participant variation. This replication study addresses these areas and the findings from the replication reflect those reported by Salsbury et al., providing support for the notion that developing L2 lexicons move from the production of words with stronger links to core lexical items to words with weaker links to core lexical items over time. Implications for language learning and teaching are discussed.

Improvement in second-language (L2) perception has been posited to occur early in L2 learning when the L2 vocabulary is still small, whereas a large L2 vocabulary curtails perceptual learning (the perceptual assimilation model for SLA [PAM-L2]; Best & Tyler, 2007). This proposition is extended by suggesting that early L2 lexical development facilitates the establishment of phonological categories in a manner analogous to children’s first-language (L1) acquisition before as opposed to after the vocabulary spurt. According to this view, L2 speech should be assimilated more consistently to L1 phonological categories and cross-boundary contrasts should be discriminated more accurately by learners with larger L2 vocabularies. To test this proposition, a novel whole-system approach to evaluate perception of L2 vowels in two experiments was applied. In Experiment 1, Japanese learners of Australian English (AusE) with less than 12 weeks of L2 learning in Australia completed labeling and goodness ratings on all AusE vowels, selecting from among all monomoraic and bimoraic Japanese vowels and vowel combinations. They also discriminated four L2 vowel contrasts, representing a range of PAM-L2 contrast types, and completed a L2 vocabulary size assessment. Learners with larger vocabularies had more consistent L2-L1 vowel assimilation and more accurate cross-boundary discrimination than those with smaller vocabularies, supporting the proposition that lexical development assists L2 phonological acquisition. Experiment 2 compared the perception of AusE vowels by Japanese learners after only 4–8 weeks in Australia with their perception after 6–8 months of L2 exposure. The results also supported the predicted positive association between L2 vocabulary size and L2 vowel perception rather than a general prediction of increased exposure duration leading to improved perception.
