We tested a theoretical model that integrated regulatory focus, second language (L2) self-guides, anxiety and enjoyment, eager and vigilant L2 use, and L2 achievement. We collected data from 324 students learning English as a foreign language. Structural equation modeling results showed that (a) the promotion focus positively predicted ideal…

This study examined the acquisition of preposition placement in English as a second language from a usage-based perspective. German and Chinese learners of English and English native speakers rated the acceptability of English oblique "wh" relative clauses in a magnitude estimation task. Results indicated that acceptability depended on…

This study employed a targeted phonetic instruction to explore the mechanisms that underpin second language (L2) phonetic acquisition. Broadly, two general approaches to phonetic acquisition have been previously proposed. A segmental approach suggests that learners acquire a series of individual, discrete phonemes (e.g., Flege, 1995), while a…

Obtaining quick and reliable evidence regarding the proficiency of learners is a perennial issue in second language (L2) learning research. In this study, we examined naturalistic utterance recall as a measure of L2 learning proficiency that can be easily extracted from videos and automatically scored using the video's captions. In our recall…

Frequency is often the only variable considered when researchers or teachers develop vocabulary materials for second language (L2) learners. However, researchers have also found that many other variables affect vocabulary acquisition. In this study, we explored the relationship between L2 vocabulary acquisition and a variety of lexical…

Studying Latin in secondary education is still widespread in Europe and believed to result in cognitive benefits, even beyond the linguistic domain. In this study we explored the relation between such study and later academic achievement in higher education (N = 1,898). First, we demonstrated that Latin students exhibit increased levels of study…

This study addresses the role of awareness in learning and the variables that may facilitate adult second language (L2) implicit learning. We replicated Williams's (2005) study with a similar group of academic learners enrolled at university as well as a group of non-college-educated adults in order to explore the generalizability of the findings…

This article reports a meta-analysis of studies on the effects of teachers' verbal lexical explanation (TVLE), as one type of lexical focus on form, on second language vocabulary learning. The dataset for this meta-analysis included 14 studies, representing a total of 36 independent samples (N = 3,304). The results of this study reveal that TVLE…

This study examined the effect of pre-reading vocabulary instruction on learners' attention and vocabulary learning. We randomly assigned participants (L1 = 92; L2 = 88) to one of four conditions: pre-reading instruction, where participants' received explicit instruction on six novel items and read a text with the items repeated eight times;…

Although text readability has traditionally been measured based on simple linguistic features, recent studies have employed natural language processing techniques to develop new readability formulas that better represent theoretical accounts of reading processes. This study evaluated the construct validity of different readability formulas,…

This review scrutinizes the evidence concerning the factors that affect the ease with which multilinguals learn additional languages. First, I focus on language learning experiences that could help multilinguals acquire new languages (e.g., consequences of exposure, use of prior knowledge, biliteracy). I then discuss how multilinguals manage…

The Less-Is-More hypothesis was proposed to explain age-of-acquisition effects in first language (L1) and second language (L2) learning. We scrutinize different renditions of the hypothesis by examining how learning outcomes are affected by (a) limited cognitive capacity, (b) reduced interference resulting from less prior knowledge, and (c)…

Heritage Spanish is often influenced by English, and previous research on late Spanish-English bilinguals suggests that their relative clause attachment preferences in Spanish are affected by English exposure. Nevertheless, recent work with heritage speakers has revealed that early (high-proficiency) Spanish-English bilinguals demonstrate a…

This study compares the performance of native speakers and adult second language (L2) learners on tasks tapping proficiency in grammar, vocabulary, and collocations. In addition, data were collected on several predictors of individual differences in linguistic attainment, including some related to language experience (print exposure, education,…

This study compared receptive English grammar skills of two groups of 7- and 9-year-old Danish children at the beginning of second language (L2) instruction in English, and two groups of Spanish/Catalan children of the same age after several years of instruction. The study examined the influence of two language-related factors (receptive…
