This study investigated whether the role of working memory capacity varies over the course of second language (L2) morphosyntactic development. Eighty-seven beginning, intermediate, and advanced university L2 Spanish learners completed two nonverbal tasks measuring executive function (EF) and phonological working memory (PWM) in their native language (English) and two tasks measuring knowledge of ten grammatical structures in Spanish at three points during and after a semester of instruction. Robust relationships between both working memory components, especially PWM, and L2 performance, emerged only for lower level learners, particularly at the start of instruction and 3.5 months later. Findings demonstrate that the facilitative effects of cognitive ability appear to lessen with increasing L2 profi ciency and empirically support a developmental perspective of L2 learning.

This report concerns vocabulary development and its cognitive underpinning in 49 young Greek learners (M = 7 years, 8 months), after two years of intensive exposure to L2 English. The data come from an experimental school for the teaching of English in Thessaloniki, implementing innovative teaching methodologies. Testing took place in Grade 2, when participants had received significant L2 exposure (approximately 300 hours). We measured L2 vocabulary (comprehension, production) and working memory (WM), the phonological store in particular, since this shares close links with early L2 vocabulary development (Gathercole & Alloway 2008). Due to the demanding nature of the L2 communicative classroom regarding attention resources, we also investigated the role of the central executive of WM in early FL vocabulary development.

A controversial issue in bilingual research is whether in the early stages of L2 learning, access to the conceptual system involves mediation of L1 lexical representations . Category interference in translation and picture naming: Evidence for asymmetric connections between bilingual memory representations. Journal of Memory and Language, 33, 149-174] or a direct route from the L2 word [Altarriba, J., & Mathis, K. M. (1997). Conceptual and lexical development in second language acquisition. Journal of Memory and Language, 36, 550-568;. Semantic category effects in second language word learning. Applied Psycholinguistics, 24, 369-383]. The main goal of this paper is to study, in a child population, whether the creation of conceptual representations for L2 words is possible, even after only one session of learning of the L2 vocabulary. Furthermore, we do so by examining the efficacy of two different L2 learning methods: L2-L1 association learning vs. L2-picture association learning. A translation recognition task was employed to test whether there was a difference between a semantically related pair and an unrelated pair across conditions (i.e., a semantic interference effect). Results showed a significant semantic interference effect-a conceptual effect-in children after just one vocabulary learning session. Importantly, the L2-picture method produced a greater semantic interference effect than the L2-L1 method. The implications of these findings for models of bilingual memory are examined.
The development of lexical fluency in a second language
Second Language Research, 2002
A goal of second language (L2) learning is to enable learners to understand and speak L2 words without mediation through the first language (L1). However, psycholinguistic research suggests that lexical candidates are routinely activated in L1 when words in L2 are processed. In this article we describe two experiments that examined the acquisition of L2 lexical fluency. In Experiment 1, two groups of native English speakers, one more and one less fluent in French as their L2, performed word naming and translation tasks. Learners were slower and more error prone to name and to translate words into L2 than more fluent bilinguals. However, there was also an asymmetry in translation performance such that forward translation was slower than backward translation. Learners were also slower than fluent bilinguals to name words in English, the L1 of both groups. In Experiment 2, we compared the performance of native English speakers at early stages of learning French or Spanish to the performance of fluent bilinguals on the same tasks. The goal was to determine whether the apparent cost to L1 reading was a consequence of L2 learning or a reflection of differences in cognitive abilities between learners and bilinguals. Experiment 2 replicated the main features of Experiment 1 and showed that bilinguals scored higher than learners on a measure of L1 reading span, but that this difference did not account for the apparent cost to L1 naming. We consider the implications of these results for models of the developing lexicon.

Executive and Phonological Processes in Second-Language Acquisition
Journal of Educational Psychology, 2012
This paper reports a latent variable study exploring the specific links between executive processes of working memory, phonological short-term memory, phonological awareness, and proficiency in first (L1), second (L2), and third (L3) languages in 8- to 9-year-olds experiencing multilingual education. Children completed multiple L1-measures of complex span, verbal short-term storage, and phonological awareness, and tests of proficiency in a range of linguistic domains (vocabulary, grammar, and literacy) in Luxembourgish (L1), German (familiar L2) and French (unfamiliar L3). Results indicate that executive processing abilities, phonological short-term memory, and phonological awareness operate as distinct but related constructs that manifest differential associations with native and second language proficiency in multilingual children: Phonological short-term memory was uniquely linked to vocabulary in L1 and the structurally similar L2; executive processes were related to grammar across languages, reading comprehension, and spelling; and phonological awareness made specific contributions to word decoding, spelling, and language proficiency in the structurally dissimilar L3. Phonological processing abilities appear to be critical for acquiring the sound structure of a new language, whereas executive processes share more general links with higher-order linguistic abilities in second language learners.
The present study was an attempt to investigate the differences in the accessibility of phonological, semantic, and orthographic aspects of words in L2 vocabulary learning. For this purpose, a sample of 119 Iranian intermediate level EFL students in a private language institute in Karaj was selected. All of the participants received the same instructional treatment. At the end of the experimental period, three tests were administered based on the previously-taught words. A subset of Gardner's' (1983) Multiple Intelligences questionnaire was also used for data collection. A repeated measures one-way ANOVA procedure was used to analyze the obtained data. The results showed significant differences in the accessibility of phonological, semantic, and orthographic aspects of words in second language vocabulary learning. Moreover, to investigate the relationships between spatial and linguistic intelligences and the afore-mentioned aspects of lexical knowledge, a correlational analysis was used. No significant relationships were found between spatial and linguistic intelligences and the three aspects of lexical knowledge. These findings may have theoretical and pedagogical implications for researchers, teachers, and learners.
Educational policies that impact second language (L2) learners—a rapidlygrowing group—are often enacted without consulting relevant research. This review synthesized research regarding optimal conditions for L2 acquisition, facilitative L2 learner and teacher characteristics, and speed of L2 acquisition, from four bodies of work—foreign language education, child language research, sociocultural studies, and psycholinguistics—often overlooked by educators. Seventy-one peer-reviewed journal articles studying PK-12 L2 learners met inclusion criteria. Findings included: 1) Optimal conditions for L2 learners immersed in a majority-L2 society include strong home literacy practices, opportunities to use the L2 informally, well-implemented specially-designed L2 educational programs, and sufficient time devoted to L2 literacy instruction, whereas L2 learners with little L2 exposure require explicit instruction to master grammar; 2) L2 learners with strong L2 aptitude, motivation, and first language (L1) skills are more successful; 3) Effective L2 teachers demonstrate sufficient L2 proficiency, strong instructional skills, and proficiency in their students' L1; 4) L2 learners require 3-7 years to reach L2 proficiency, with younger learners typically taking longer but more likely to achieve close-to-native results. These findings, even those most relevant to education, are not reflected in current US policy. Additional research is needed on the characteristics of successful or unsuccessful L2 learners and L2 teachers. Such research should attend systematically to the differences between L2 learning in maximal versus minimal input settings; whereas the psycholinguistic challenges of L2 learning might be common across settings, the sociocultural and interactional challenges and opportunities differ in ways that can massively impact outcomes.
