Age of first exposure (AoFE) is an important factor that influences the quality of L2 acquisition. This study aims to investigate the AoFE effect on the contextual learning of L2 novel words at the neural level, as measured by the N400 component from event-related potentials (ERPs). Eighty-eight participants were recruited for the experiment of L2 pseudoword learning, which includes a learning session and a testing session. The participants’ EEG data were recorded from the testing session, and the N400 effect was derived from target words that were either congruous or incongruous with the context. The linear mixed model and multiple regression model revealed a positive AoFE effect on the N400 effect in discourses that were designed for testing retrieval of episodic and semantic memory even after accounting for the variance contributed by several confounding factors. In addition to AoFE, the effects of total L2 exposure, L2 proficiency and personality on the L2 novel word learning performance indicated by the N400 effect were also confirmed in the statistical results.

The purpose of this article is to investigate the interactional strategies that secondary school EFL learners use during telecollaboration with interlocutors from a different cultural and linguistic background. Its novelty lies in the educational level and cultural contexts explored as well as in the goal of examining whether frequency of strategy use may depend on the interlocutor and, if so, what the relevant factors are for such variation. The study focuses on two projects in which 10 participants from one Bulgarian school and 18 partners from two schools in Spain took part in dyadic synchronous videoconferences discussing culture-related topics. Data were collected via video recordings, field observations, semi-structured interviews, and questionnaires. The article presents both descriptive statistics and qualitative analysis of the communicative behavior of three case study students interacting with different telecollaborative partners. We found that the participants demonstrate differences in interactional behavior and utilize strategies with varying frequency depending on their interlocutor. The results also reveal crucial factors in the design of telecollaborative educational projects if learners are to successfully implement skills of discovery and interaction in real time.

The Aspect Hypothesis (AH) claims that L2 beginners use the perfective morpheme first with telic predicates (e.g., ‘arrive’, ‘build the house’) and only later with atelic ones (e.g., ‘know’, ‘work’). In contrast, the Lexical Underspecification Hypothesis (LUH) claims that beginners cannot represent the lexical aspect of L2 predicates (hence the telic vs. atelic distinction), because this distinction is a separate component of verb meaning. To investigate whether L2 learners distinguish between telic and atelic predicates, this study compares the responses from 299 L2 Italian learners (with different L1 backgrounds) and responses from 91 native speakers (NS) to the “for/in + time span” adverbial test (Dowty 1979). The analysis shows that native speakers and L2 learners’ responses to the adverbial test diverge significantly, with learners’ proficiency and – to a lesser extent – L1 modulating their ratings. The results suggest that native speakers and beginning-intermediate L2 learners might not represent telicity alike, either because L2 aspectual competence is still developing or because beginning learners rely on the semantic representations of their L1. These findings support the predictions of the LUH and suggest caution when trying to assess learners’ aspectual representations.

Bringing together lines of research from sentence processing and lexical access, this empirical study investigates the interplay between lexical (grammatical gender) and syntactic (word order) cross-linguistic overlap in L2 German. Eighty-six L1 Spanish-L2 German and thirty-six monolingual German adults completed a German self-paced reading task with noun phrases (NPs) manipulated by L1-L2 gender congruency (congruent, incongruent, neuter) and L1-L2 adjective-noun word order (pre- vs. postnominal adjectives). The study examines the effects of gender congruency, the type of L1-L2 gender mapping (i.e., presence vs. absence of each class in L1 and L2), and L2 proficiency level. Results show that the detection of ungrammatical word order in L2 German interacts with gender congruency, in that L2 speakers are only sensitive to word order violations for sentences with gender-congruent nouns. The detection of ungrammaticality for sentences containing gender-incongruent nouns only emerges at higher L2 proficiency levels. These findings underscore the role of cross-linguistic lexical overlap in syntactic processing.

We introduce the blueprint of the Ontogenesis Model of the L2 Lexical Representation (OM) that focuses on the development of lexical representations. The OM has three dimensions: linguistic domains (phonological, orthographic, and semantic), mappings between domains, and networks of lexical representations. The model assumes that fuzziness is a pervasive property of the L2 lexicon: most L2 lexical representations are low resolution and the ontogenetic curve of their development does not reach the optimum (i.e., the ultimate stage of their attainment with optimal encoding) in one or more dimensions. We review the findings on lexical processing and vocabulary training to show that the OM has a potential to provide an interpretation for the results that have been treated separately and to move us forward in building a comprehensive model of L2 lexical acquisition and processing.

In the context of theories of statistical learning, frequency of encounter is viewed as a major driving force in L2 acquisition. The present paper challenges this position with respect to core components at the level of language competence which relate to language-specific patterns in cognitive construal. Empirical evidence from very advanced L2 speakers (L1 French, L2 English and L2 German) shows that forms and constructions which are highly frequent in the target languages in the expression of motion events are not used in a target-like form by L2 speakers. The study shows how the basis for language use which is not target-like lies at the level of event construal: conceptual frames, which are language-specific and are deeply anchored in the course of L1 acquisition, drive allocation of attention and the extraction of forms in L2 acquisition. Findings in the domain of spatial cognition show that motion event frames based on the L1 take precedence over frequency of occurrence of forms in the target language as a factor in L2 use.

Referential metonymy, e.g. ‘the moustache (= man with a moustache) sits down first’, appears early in L1 acquisition (Falkum, Recasens & Clark, 2017). Yet how does it emerge in pragmatically mature but linguistically developing adult L2 learners? We used one comprehension and two production tasks, based on Falkum and colleagues (2017), to investigate metonymy abilities in 34 Japanese adult learners of English as an additional language (EAL) and a control group of 31 native English speakers. We also examined how time constraints and exposure to examples of referential metonymy affected production. In the comprehension task, both EAL-learner and native-speaker participants chose metonymic readings at above chance levels. In both production tasks, all participants produced innovative metonyms. Additionally, the findings indicate that, in L2, exposure to examples dramatically increases metonymy production, while time pressure decreases it. The results suggest that participants can both comprehend and produce novel metonyms in L2, with a possible explicitness vs. production costs trade-off.

This study investigates the acquisition of articles in L2 English by L1 speakers of Dagbani, a Gur language spoken in Ghana. Dagbani differs from English in that it has two definite articles, no indefinite article, and a zero-article which may express definiteness, indefiniteness as well as genericity. The study consisted of a Forced-choice task (FCT) and an Acceptability judgement task (AJT) which were administered to Dagbani teenagers with an intermediate proficiency in English (n = 45) and a group of native English speakers as controls (n = 8). The results showed that the learners’ article choice was based on definiteness, not specificity (i.e., no fluctuation between the two) and that they had slightly more problems with indefinite than definite contexts, while generic contexts were the most problematic. Except for a certain task effect as well as a possible interference of instruction (in the FCT), the results can be argued to generally be due to influence from the L1 and to the difficulty of feature reassembly.

We evaluated the impact of gestures on second language (L2) vocabulary learning with nouns (Experiment 1) and verbs (Experiment 2). Four training methods were compared: the learning of L2 words with congruent gestures, incongruent gestures, meaningless gestures, and no gestures. Better vocabulary learning was found in both experiments when participants learned L2 words with congruent gestures relative to the no gesture condition. This result indicates that gestures have a positive effect on L2 learning when there is a match between the word meaning and the gesture. However, the recall of words in the incongruent and meaningless gesture conditions was lower than that of the no gesture condition. This suggests that gestures might have a negative impact on L2 learning. The facilitation and interference effects we found with the use of gestures in L2 vocabulary acquisition are discussed.

In the visual domain, more than two decades of work has argued for the existence of dual category learning systems. The reflective system uses working memory in an explicit fashion to develop and test rules for classifying. The reflexive system operates by implicitly associating perception with actions that lead to reinforcement. Dual-system models posit that in learning natural categories, learners initially use the reflective system and with practice, transfer control to the reflexive system. The role of reflective and reflexive systems in second language (L2) speech learning has not been systematically examined. In the study reported in this paper, monolingual native speakers of American English were trained to categorize Mandarin tones produced by multiple speakers. Our computational modeling approach demonstrates that learners use reflective and reflexive strategies during tone category learning. Successful learners use speaker-dependent, reflective analysis early in training and reflexive strategies by the end of training. Our results demonstrate that dual-learning systems are operative in L2 speech learning. Critically, learner strategies directly relate to individual differences in successful category learning.

This paper investigates Japanese speakers’ acquisition of the mass–count distinction in English. Learners judge whether two large objects/portions of stuff are more than six tiny objects/portions of stuff or vice versa. Results show that learners correctly base judgments on number for count nouns (judging that six small cups are more cups than two large cups) and object-mass nouns (e.g., furniture) and on volume for substance-mass nouns (judging that two large portions of mustard are more mustard than six tiny portions of it). For nouns that can be either mass or count in English (e.g., string(s)) or cross-linguistically (e.g., “spinach”), learners fail to shift judgments according to the mass–count syntax in which the words appear. Results suggest that Japanese learners have difficulty using mass–count syntactic cues to disambiguate the meanings and thus fail to acquire the mass–count distinction in English.

This study investigates definite articles in specific and generic subject nominals in Italian spoken by adult simultaneous bilinguals (2L1ers) and second language learners (L2ers). The study focuses on plural and mass DPs, in which German and Italian differ. The aims are to (i) compare acquisition outcomes between the weaker and the stronger language in 2L1 acquisition, (ii) see in a comparison with L2ers whether the phenomenon under investigation, which is typically acquired late (after age 6;0), lacks age of onset effects, and (iii) discuss predictions for the directionality of cross-linguistic influence. Twenty German–Italian 2L1ers and 15 advanced L2ers of Italian with German as their native language were tested in an acceptability judgment task and a truth value judgment task. The results show clear differences between Italian as the weaker and as the stronger language in 2L1 acquisition, and similarities between Italian as L2 and as the weaker language in 2L1 acquisition.

This study compares mastery of gender assignment and agreement in Italian by adult Italian–German bilinguals who have acquired two languages simultaneously (2L1), and by adult German highly proficient second language learners (L2ers) of Italian. Our data show that incompleteness in bilingual acquisition and in second language (L2) acquisition primarily affects gender assignment: the categorization of nouns and the interpretable gender feature are subject to vulnerability in the two modalities of acquisition. Overall, mastery of morpho-syntax (i.e., gender agreement) was nearly native-like for both groups of speakers, suggesting that uninterpretable features are unlikely to be subject to vulnerability in the heritage language of adult bilingual speakers and can be acquired in adult L2 acquisition. Deviances from the target in gender assignment and, to a lesser extent, in gender agreement are attributed to both language-internal (i.e., language) and language-external factors (i.e., amount of input).

Despite the spread of reliable desktop audio and videoconferencing facilities, some CMC-based projects still rely on asynchronous written environments, if only because of the temporal constraints of synchronicity (Guichon, 2009; Develotte, Guichon & Vincent, 2010). Yet speaking is usually the skill students most need to improve when learning a second language (L2). This paper therefore sets out to measure the impact of distant written exchanges between Native Speakers (NS) and Non Native Speakers (NNS) on the development of NNS L2 oral output, focusing specifically on the effect of phonological nativisation. The context of this study is a teacher training programme for future primary school teachers in France. During their L2 course aiming to help them improve their mastery of English, they were given the opportunity to take part in a CMC-based project with PGCE (Postgraduate Certificate in Education) students from King's College, London. Action research was thus carried out to examine the potential of this project in the development of the participants’ L2 oral output.

The L2 course being task-oriented, the trainee teachers’ L2 oral output was evaluated by means of pre- and post-tests based on tasks. The results show that stability prevails over progress, which is in keeping with the fact that interlanguage development is a long process (Chapelle, 2003: 119). The results also confirm the importance of phonological nativisation when learners have access only to written authentic input.

The present study compares the relative effect of inherent lexical aspect and discursive grounding on the use of L2 Spanish Preterit and Imperfect. The study is based on the analysis of responses to a written 40-item discourse-based forced-choice task among 286 English-speaking learners of Spanish. The analysis of data (repeated measures ANOVA) reveals that as learners gain more experience with the target language, the effect of both lexical aspect and grounding on past tense marking increases. That is, contrary to previous predictions, learners constantly move towards prototypical associations of lexical-narrative factors with morphological markers as knowledge of the second language increases. Second, grounding is the construct that most clearly distinguishes learners from native speakers.

This article focuses on the methodological challenges involved in investigating anaphoric binding in Norwegian as a second language. Norwegian anaphors can be bound both locally and non-locally, and since anaphors vary cross-linguistically, it is interesting to explore whether and where L2 speakers of Norwegian allow such target-like local and non-local binding in their L2. Sentences with two possible antecedents might be ambiguous for L2 speakers, and the truth-value judgment task is generally considered to be the best method for eliciting knowledge of L2 speakers' intuitions of anaphoric binding in ambiguous sentences. In Norwegian, long-distance binding cannot cross a finite clause boundary, and the long-distance anaphor cannot be locally bound. Because of this, the truth-value judgment task is sometimes less adequate for testing all relevant binding structures in Norwegian. Dialectal variations in Norwegian pose additional challenges for the study of the acquisition of anaphors in an L2. This paper discusses the implications of these methodological challenges.
