The type of processing–resource allocation (TOPRA) model predicts that increasing one type of processing (semantic, structural, or mapping oriented) can decrease other types of processing and their learning counterparts. This study examined how semantic and structural tasks affect the mapping component of second language (L2) vocabulary learning. Japanese-speaking L2 English learners attempted to map secondary meanings of 24 English homographs. Each participant studied them (a) while making pleasantness ratings about word meaning (mapping plus semantic processing); (b) while counting letters in each word (mapping plus structural processing); and (c) without any additional task (mapping only). Results of L1 (first language) and L2 free recalls and L2-to-L1 and L1-to-L2 cued recalls indicated higher free recall in the semantic condition over the structural condition and higher cued recall in the mapping condition over the semantic and structural conditions, providing qualitatively new evidence for TOPRA model predictions.

This study considers the role of L1 phonological influence in L2 English past tense morphology production by native speakers of Spanish, Mandarin, and Japanese. While these L1s share similar phonological restrictions on consonant cluster formation needed for English past tense morphology, differences arise in L1 syntax (only Mandarin lacks syntactic past) and L1 prosodic structure (only Japanese has English-equivalent structure). Aggregate analyses indicate that an L1 English control group outperforms all L2 groups in oral suppliance of past tense morphology. Results therefore reveal that having the syntactic feature for past in the L1 does not translate into targetlike performance and that L1 phonological restrictions alone cannot fully explain nontargetlike performance. Considering previous and the current data sets, we argue that evidence from production of L2 English past tense cannot be used to adjudicate between representational deficit approaches and full access approaches, contrary to what has been argued previously.

It has been known since at least the 1960s that small changes in pupil diameter in response to a mental task are indicative of processing effort associated with this task. More recently, with the advent of modern eye-trackers, which also measure the pupil diameter, pupillometry has been “rediscovered” by language researchers and the method has since been used in many different subdisciplines of linguistics. This article gives a nonexhaustive overview about recent linguistic research with the purpose of introducing researchers in the field of second language acquisition (SLA) to pupillometry. In addition, the article discusses things to consider when designing an experiment and how pupil data can be analyzed. The range of possibilities in which pupillometry can be used in experimental SLA research makes it a welcome addition to other online methods such as eye-tracking and event-related potentials.

Research has begun to demonstrate that L2 words can be learned incidentally through watching audio-visual materials. Although there are a large number of studies that have investigated incidental vocabulary learning through reading a single text, there are no studies that have explored incidental vocabulary learning through viewing a single full-length TV program. The present study fills this gap. Additionally, three word-related variables (frequency of occurrence, cognateness, word relevance) and one learner-related variable (prior vocabulary knowledge) that might contribute to incidental vocabulary learning were examined. Two experiments were conducted with Dutch-speaking EFL learners to measure the effects of viewing TV on form recognition and meaning recall (Experiment 1) and meaning recognition (Experiment 2). The findings showed that viewing TV resulted in incidental vocabulary learning at the level of meaning recall and meaning recognition. The research also revealed that learning was affected by frequency of occurrence, prior vocabulary knowledge, and cognateness.

The Spanish mood contrast is a good test case for research on acquiring form-meaning connections in contexts where input is variable and multiple areas of the grammar are implicated (e.g., syntax, semantics, pragmatics). Nevertheless, research on interpretation of this contrast lags and little is known about how individual lexical items and patterns of co-occurrence of adverbial clauses with subjunctive forms influence interpretation. Addressing this void, we compare interpretation of the present subjunctive by native speakers (NSs) and nonnative speakers (NNSs) at three relatively high levels of experience. Participants completed an interpretation task containing clauses with indicative and subjunctive forms paired with one of six adverbial conjunctions, categorized as co-occurring with subjunctive, indicative, or both forms. Our analysis suggests individual lexical items play a role in morphosyntactic variation and that nuanced differences in interpretation exist for NSs and highly advanced NNSs, even on items that prescriptively co-occur with only one form.

The purpose of the present study was to examine the relations between emotions, classroom environment, and willingness to communicate (WTC) using the advanced quantitative methodological procedure of doubly latent multilevel analysis. To this end, 1528 secondary school students from 65 different classrooms in Iran participated in the study. Results of the doubly latent multilevel analysis showed that a positive classroom environment is related to fostering WTC and enjoyment, while it reduces anxiety among students. Moreover, enjoyment was found as an important factor in increasing WTC at both student and classroom level, while anxiety reduced WTC only at the student level. Finally, the results of the study are discussed and pedagogical implications are provided for language teachers.

Definite discourse-new bridging reference (e.g., a school … the teacher; Clark, 1975) is a complex syntax-pragmatic component of referential movement, one that is subject to relatively opaque form-function contingency compared with forms used for discourse-old reference, and one that is especially prone to crosslinguistic influence. Research shows Asian second language (L2) learners of English struggle to produce bridging reference appropriately, yet little research has been done on the L2 production of bridging in Asian languages. We collected oral picture sequence narrative data from 80 lower-intermediate L2 Mandarin learners from first language (L1) English (+ article, n = 23) and L1 Korean and Japanese (- article, n = 57) backgrounds, alongside equivalent L1 data. Speakers of article-L1s were more likely than those from article-less L1s to use numeral + classifier noun phrases (NPs) for nonbridging referents and demonstrative + classifier NPs when introducing bridging referents, essentially (and infelicitously) using these constructions as de facto English-like indefinite/definite articles in their L2 Mandarin production. Speakers of article-less languages infelicitously marked bridging relations with nonbridging forms. These findings confirm substantial crosslinguistic difficulties for the L2 marking of this complex syntax-pragmatic phenomenon across relatively underexplored L1/L2 pairs.

This study explored the roles of exposure frequency, aural enhancement (AE) of input, and individual differences in working memory (WM) during L2 incidental vocabulary learning while reading. Eighty intermediate-level English learners were divided into four treatment groups, and given reading tasks with target words embedded two or four times. Listening while reading was controlled, as well as duration of exposure to new words through timed reading tasks, and comprehension questions helped to ensure a focus on meaning. Surprise posttests assessed initial form recognition and form-meaning connections. Proficiency and WM measures were administered, with English proficiency used as a covariate. Results indicated that measurable learning occurred at the two-exposure level for new words, both in form recognition and form-meaning connections. Frequency effects held from two to four exposures across AE and non-AE conditions, but were influenced by AE on the form-meaning outcome. This indicated support for simultaneous input modalities facilitating deeper processing and better learning outcomes. WM outcomes correlated with vocabulary outcomes for form recognition, and an aptitude by treatment interaction was found for form recognition.

This study investigates whether repeating a prime sentence aloud strengthens short-term and longer-term priming of adverb-first word order among adult intermediate L1 English-German L2 learners (N = 30). Compared to an earlier study (Jackson & Ruf, 2017), in which similarly proficient L1 English-German L2 learners heard, but did not repeat, prime sentences, participants in the present study exhibited greater short-term priming for adverb-first word order during the priming phase and significant longer-term priming in a posttest phase immediately following the priming phase. However, additional analyses revealed that only those participants who exhibited stronger short-term priming without lexical overlap during the priming phase continued to produce adverb-first sentences in the posttest phase, highlighting that even prime repetition may not support longer-term priming among intermediate L2 learners more generally.

Since the Shallow Structure Hypothesis (SSH) was first put forward in 2006, it has inspired a growing body of research on grammatical processing in nonnative (L2) speakers. More than 10 years later, we think it is time for the SSH to be reconsidered in the light of new empirical findings and current theoretical assumptions about human language processing. The purpose of our critical commentary is twofold: to clarify some issues regarding the SSH and to sketch possible ways in which this hypothesis might be refined and improved to better account for L1 and L2 speakers’ performance patterns.
