This study investigates the validity of syntactic priming as a measure of implicit language aptitude. Syntactic priming refers to the tendency to reproduce a linguistic structure due to a previous exposure to the structure. The validity of the construct was verified by collating evidence for divergent validity—whether it is dissociable from explicit aptitude; convergent validity—whether it is correlated with other measures of implicit aptitude; and predictive validity—whether it is predictive of learning attainment. One hundred sixty-six university EFL learners completed three tests of implicit aptitude: syntactic priming, sequence learning, and LLAMA_D; three tests of explicit aptitude: LLAMA_B, _E, and _F; and three tests of L2 proficiency: untimed grammaticality judgment, metalinguistic knowledge, and elicited imitation. The results showed that syntactic priming was dissociable from explicit aptitude, but it failed to converge with the other measures of implicit aptitude, and it also failed to predict L2 proficiency. The results also showed that priming was negatively correlated with sequence learning and that sequence learning was a negative predictor of learners’ metalinguistic knowledge. On the other hand, the construct validity of explicit aptitude was strong. The results suggest the multidimensionality of implicit aptitude and the need for more research into the construct validity of syntactic priming as a cognitive ability for implicit learning.

We investigate effects of prosodic cues on interpretation of ambiguous sentences containing relative clauses (RCs) in English by Spanish-speaking learners. English and Spanish differ in default preference for RC attachment: English has a weak low attachment (LA) preference (RC modifies NP2); Spanish has a stronger high attachment (HA) preference (RC modifies NP1). We conducted an interpretation task with auditorily presented stimuli to examine whether prosodic cues determine attachment. Target items were manipulated for position of break and length of RC, NP1, and NP2. For both groups, break and length are significant. For the learners, proficiency interacts with break suggesting L1 transfer: lower proficiency learners choose HA more when break points to LA; higher proficiency learners choose HA more when break points to HA. Lower proficiency learners are more likely to choose LA overall, suggesting a recency effect. Our results confirm the importance of using aural stimuli when testing interpretation of ambiguous sentences.

Little research has been done on the effect of learning context on L2 listening development. Motivated by DeKeyser’s (2015) skill acquisition theory of second language acquisition, this study compares L2 listening development in study abroad (SA) and at home (AH) contexts from both language knowledge and processing perspectives. One hundred forty-nine Chinese postgraduates studying in either China or the United Kingdom participated in a battery of listening tasks at the beginning and at the end of an academic year. These tasks measure auditory vocabulary knowledge and listening processing efficiency (i.e., accuracy, speed, and stability of processing) in word recognition, grammatical processing, and semantic analysis. Results show that, provided equal starting levels, the SA learners made more progress than the AH learners in speed of processing across the language processing tasks, with less clear results for vocabulary acquisition. Studying abroad may be an effective intervention for L2 learning, especially in terms of processing speed.

Since 2015, increased numbers of newly immigrated schoolchildren in Europe have resulted in divergent, often ad hoc measures to provide for their education. Because the basis of classroom learning is information found in written texts, the development of grade-level reading skills is of central importance. However, little is known about immigrant students’ reading skills at and following transition, and no data is available for Germany, where the study was conducted. We report the results of a longitudinal study in which migrant students’ (N = 136) reading subskills after transition into mainstream were investigated at three points over the course of 2 years and compared to cohort performance (N = 517) in grades 7 through 9. Results showed that immigrant students performed significantly below mainstream students on all measures for all data points, with little evidence that they are beginning to close the gap even after several years in mainstream.

This study explored the interaction between learning conditions, linguistic complexity, and first language (L1) syntactic transfer in semiartificial grammar learning by conceptually replicating and extending Tagarelli et al. (2016). We changed the L1 background, elicited production data during debriefing, and added a binary mixed-effects logistic regression analysis to compare variability at learner and item levels with group-level variation on exposure condition, linguistic complexity, and their interaction. Our results replicated those of the original study regarding the comparative efficacy of explicit instruction; however, we also found a condition × complexity interaction absent in the original study. Debriefing sentence-production data suggest that the changed L1-L2 typological distance may have leveled off the advantage of explicit instruction in the learning of the complex V2-VF structure. Finally, our mixed-effects modeling analysis revealed that variability at learner and item levels accounted for a larger proportion of the variance of the outcomes than all the predictors combined.

Although recent research suggests that gains are made in the acquisition of dialectal features during study abroad, the few studies that have been conducted on this topic in Spanish-speaking contexts have focused primarily on features characteristic of Spain. This article examines the L2 acquisition of phonological features characteristic of Buenos Aires Spanish, [ʃ] and [ʒ], known as sheísmo/zheísmo, for example the pronunciation of llave [ʝaβe] “key” as [ʃaβe] or [ʒaβe]. Participants include 23 learners of Spanish studying in Buenos Aires, Argentina. More than 4,800 tokens were gathered before, during, and at the end of the semester using sociolinguistic interviews, a reading passage, and a word list. These data were analyzed for the influence of linguistic and social factors using mixed-effects logistic regression (Rbrul; Johnson, 2009). Results suggest that participants approximate nativelike norms of use of these features and that time in country is a statistically significant predictor of patterns of phonological variation.

Speakers show cross-linguistic differences in expressing placement events involving support (cup on table) and containment (apple in bowl) in first language (L1) contexts. They rely on either more-general (e.g., Spanish for support, Polish for containment) or more-specific (e.g., German, Polish for support; Spanish, German for containment) descriptions. Relatively less is known about the expression of placement events in second language (L2) production contexts. In this study, we examined object-placement event descriptions produced by two groups of L1 Polish speakers—with either German or Spanish as their L2—in comparison to monolingual speakers of German, Spanish, and Polish, using an animated event description task. Bilingual speakers showed greater effect of L1 patterns in moving from a more-general to a more-specific system and L2 patterns in moving from a more-specific to a more-general or between two more-specific systems, suggesting that the specificity of event expression in L1 influences patterns of placement expression in L2.

This study addresses the role of domain-general mechanisms in second-language learning and knowledge using an individual differences approach. We examine the predictive validity of implicit-statistical learning aptitude for implicit second-language knowledge. Participants (n = 131) completed a battery of four aptitude measures and nine grammar tests. Structural equation modeling revealed that only the alternating serial reaction time task (a measure of implicit-statistical learning aptitude) significantly predicted learners’ performance on timed, accuracy-based language tests, but not their performance on reaction-time measures. These results inform ongoing debates about the nature of implicit knowledge in SLA: they lend support to the validity of timed, accuracy-based language tests as measures of implicit knowledge. Auditory and visual statistical learning were correlated with medium strength, while the remaining implicit-statistical learning aptitude measures were not correlated, highlighting the multicomponential nature of implicit-statistical learning aptitude and the corresponding need for a multitest approach to assess its different facets.

Evidence for the role of procedural memory in second language (L2) acquisition has emerged in our field. However, little is known about the reliability and validity of the procedural memory measures used in this research. The present study (N = 119) examined the reliability and the convergent and discriminant validity of three assessments that have previously been used to examine procedural memory learning ability in L2 acquisition, the dual-task Weather Prediction Task (DT-WPT), the Alternating Serial Reaction Time Task (ASRT), and the Tower of London (TOL). Measures of declarative memory learning ability were also collected. For reliability, the DT-WPT and TOL tasks met acceptable standards. For validity, an exploratory factor analysis did not provide evidence for convergent validity, but the ASRT and the TOL showed reasonable discriminant validity with declarative memory measures. We argue that the ASRT may provide the purest engagement of procedural memory learning ability, although more reliable dependent measures for this task should be considered. The Serial Reaction Time task also appears promising, although we recommend further consideration of this task as the present analyses were post hoc and based on a smaller sample. We discuss these results regarding the assessment of procedural memory learning ability as well as implications for implicit language aptitude.

Learning a second/foreign language (L2) is a long process and L2 learners certainly will encounter setbacks and discouragements during this process. However, their reactions to these failures might be different based on their perceptions of L2 learning ability and their subsequent effort put into L2 learning. Based on this, the present study aimed at exploring two underresearched constructs within the field of applied linguistics, namely grit (continuous effort and interest for long-term goals) and language mindset (individuals’ perceptions of their language learning ability). We had five main aims: to examine (a) the factor structure of grit, (b) the factor structure of language mindset, (c) whether there are gender differences in grit or language mindset, (d) the relationships between language mindset and grittiness, and (e) the roles of grit and language mindset as predictors of L2 achievement. To address these aims, a total number of 1,178 university students who were taking general English courses took part in our study and completed the questionnaires. Results of confirmatory factor analysis indicated that the two-factor structure for both grit and language mindset fit the data better than the single-factor structure. We also tested several structural equation models and found that a growth language mindset weakly, but positively, predicted one component of grit (perseverance of effort, or POE), but not the other (consistency of interest, or COI). A fixed language mindset did not predict POE, but did negatively predict COI. Finally, only growth language mindset was a weak, positive predictor of L2 achievement. At the end, theoretical and pedagogical implications regarding the role of grit and language mindset in L2 learning are presented.

Implicit causality (IC) is a well-known phenomenon whereby certain verbs appear to create biases to remention either their subject or object in a causal dependent clause. This study investigated to what extent Korean learners of English made use of IC information for predictive processing at a discourse level, and whether L2 proficiency played a modulating role in this process. Results from a visual-world eye-tracking experiment showed early use of IC information in both L1 and L2 listeners, yet the effect was weaker and emerged later in the L2 group. None of three independent and intercorrelated proficiency measures modulated L2 listeners’ processing behavior. The findings suggest that L2 listeners are able to engage in prediction during real-time processing at a discourse level, although they did so to a more limited extent than native speakers in this study. We discuss these findings in light of similar evidence from other recent work.

Pitch perception plays a more important role in emotional communication in English than in Korean. Interpreting the semantic aspects of pitch levels therefore presents a challenge for Korean learners of English. This study investigated how 49 Korean learners of English perceived 20 English emotional utterances. Participants were asked to complete a congruency task in which they indicated whether the category of the semantic valence was congruent with the intonation type. They also described each emotional utterance by providing an adjective. The task results of Korean participants were compared with those of a control group of 49 Anglo-American students. Statistical analyses revealed that the incongruence between the semantic meaning and the intonation type interfered with American participants’ performance more than Korean participants. The adjective task results also showed that American participants were more attuned to the interplay between the semantic meaning and the intonation type than Korean participants.

There has recently been a surge of interest in improving the replicability of second language (L2) research. However, less attention is paid to replicability in the context of L2 meta-analyses. I argue that conducting interrater reliability (IRR) analyses is a key step toward improving the replicability of L2 meta-analyses. To that end, I first discuss the foundation of IRR in the context of meta-analytic research. Second, I introduce two IRR measures, S index and Specific Agreement, which aid in improving the replicability of meta-analytic research. Third, I offer a flexible R program, meta_rate, to facilitate the conduct of IRR analyses for L2 meta-analyses. Fourth, I apply the R program to an actual meta-analytic L2 coding sheet to demonstrate the practical use of the IRR methods discussed. Finally, I provide interpretive guidelines to assist both L2 meta-analysts and journals with the transparent reporting of the IRR findings.

This study examines the second language (L2) development of variable /s/-weakening in the spontaneous speech of L2 learners of Spanish who studied abroad in either Dominican Republic, where /s/-weakening is widespread, or central Spain, where /s/-weakening is much less common. Learners’ realizations of /s/ were coded impressionistically and acoustically by measuring voicing, center of gravity, and duration. The results show that regardless of the study abroad location, students did not change the amount of sibilance they produced over time. However, they became more nativelike with respect to /s/-voicing and duration. Additionally, whereas some linguistic factors were found to significantly constrain /s/-weakening across groups, learners did not gain sensitivity to all factors that constrain native-speaker /s/-weakening. Findings suggest that exposure to /s/-weakening during a semester abroad is insufficient for learners to adopt this sociolinguistic variable and other social and cognitive factors likely mitigate its integration into the L2 learners’ phonological systems.

A subtest of the LLAMA test battery (LLAMA_D) has been proposed as a potential test of implicit learning aptitude. To improve its construct validity, in the present study, the original LLAMA_D (a) instructions for incidental learning were modified, and (b) confidence ratings of test responses and (c) reaction time (RT) measurements were added. This revised LLAMA_D was administered along with the other LLAMA subtests (LLAMA-B, -E, and -F). Unconscious knowledge that may (not) result from the exposure was assessed through the relationship between the accuracy/RT and confidence ratings. The results suggest that LLAMA_D accuracy largely reflects conscious retrieval of previously heard sound sequences. However, an index derived from the LLAMA_D RT measure (coefficient of variance) was associated with an aspect of oral fluency, which is presumably dependent on proceduralization. Several recommendations are proposed to redesign and extend LLAMA_D as a potential aptitude test for proceduralization.

To test the effects of talker variability and explicit instruction on the statistical learning of lexical tone, 80 monolingual English listeners were taught an artificial language that mimicked Mandarin’s asymmetric distribution of syllable-tone co-occurrences. Training stimuli consisted of either speech from one talker or speech from four talkers. Participants were either never instructed or explicitly taught associations between phonemes (CVs), tones, and nonce symbols across four consecutive days. Learning was assessed by the accuracy of mouse clicks and eye movements to visual nonce symbols. Critical trials induced competition between the target symbol, which matched the acoustic input, and a competitor symbol that had a statistically more probable tone (but mismatched the acoustic input). Eye fixations indicated that participants were sensitive to syllable-tone co-occurrence probabilities even without explicit instruction of tone. The degree to which statistical knowledge was used to recognize words appeared to increase when participants processed more variable speech.
