In this study, we investigated the accuracy of first language (L1) and second language (L2) speakers' intuitive judgments of phrasal frequency and collocation strength, and examined the linguistic influences that give rise to these judgments. L1 and L2 speakers of English judged 180 adjective-noun collocations as (a) high frequency, medium…

This article provides a conceptual review of the principles of input spacing as they might relate specifically to oral task repetition research and presents some of the common methodological considerations from the broader input spacing literature. The specific considerations discussed include the interaction between intersession intervals and…

Researchers often make claims regarding the importance of predictor variables in multiple regression analysis by comparing standardized regression coefficients (standardized beta coefficients). This practice has been criticized as a misuse of multiple regression analysis. As a remedy, I highlight the use of dominance analysis and random forests, a…

This meta-analysis aimed to clarify the complex relationship between repetition and second language (L2) incidental vocabulary learning by meta-analyzing primary studies reporting correlation coefficients between the number of encounters and vocabulary learning. We synthesized and quantitatively analyzed 45 effect sizes from 26 studies (N = 1,918)…

The comprehension of signed language requires linguistic and visual-spatial processing, such as perspective-taking for correctly interpreting the layout of a spatial scene. However, little is known about how adult second-language (L2) learners process visual-spatial constructions in a signed language that they are studying, including which angles…

Answering calls to map college-level proficiency development (Modern Language Association, 2007) and longitudinally chart language learning (Barkaoui, 2014; Ortega & Byrnes, 2008), we mapped the oral proficiency growth of 1,922 lower-division college students of Chinese, French, Russian, and Spanish (in the second, third, or fourth semester of…

This study investigated the effects of individual word frequency, collocational frequency, and association on L1 and L2 collocational processing. An acceptability judgment task was administered to L1 and L2 speakers of English. Response times were analyzed using mixed-effects modeling for 3 types of adjective-noun pairs: (a) high-frequency, (b)…

This study focused on the mechanisms underlying incidental second language (L2) vocabulary acquisition prior to formal instruction. We designed a cross-sectional study to examine which learner-related and word-related variables affect young learners' vocabulary knowledge at the level of meaning recognition and meaning recall. We collected data…

Second language acquisition (SLA) research offers valuable insight on how languages are learned and how they coexist and influence each other. Sign language learners offer unique perspectives on SLA, allowing researchers to test theories that are otherwise constrained by access to only one modality. Current literature on sign language learning…

This study aimed to investigate which word-related variables play a role in Dutch-speaking children's L2 word learning through out-of-school exposure prior to classroom instruction in the foreign language. We used different measures to investigate the role of frequency, concreteness, cognateness, and age of acquisition (AoA) in receptive…

We investigated the potential influence of implicit learning mechanisms on L2 morphosyntactic attainment by examining the relationship between age of onset (AoO), two cognitive abilities hypothesized to underlie implicit learning (phonological short-term memory and implicit statistical learning), and performance on an auditory grammaticality…

In this study, we examined the effect of previewing unfamiliar vocabulary on the real-time reading behavior of first language (L1) and second language (L2) readers. University students with English as their L1 or L2 read passages with embedded pseudowords. In a within-participant manipulation, definitions of the pseudowords were either previewed…

To date, linguistic alignment studies in second language acquisition have mainly been conducted during face-to-face (FTF) interactions. In the current study, we examined and compared the effect of structural alignment on the development of English direct and indirect questions in FTF and synchronous computer-mediated communication (SCMC) contexts.…

This study presents a corpus-based investigation of self-repairs in hearing adult L2 (M2L2, second modality and second language) learners of Swedish Sign Language ("Svenskt teckenspråk," STS). This study analyses M2L2 learners' STS conversations with a deaf signer and examines the learners' self-repair practices and whether there are…

This study investigated L2 Korean speakers' self-assessment of speech comprehensibility and accentedness, including a conceptual replication of Trofimovich, Isaacs, Kennedy, Saito, and Crowther (2016, Experiment 1) and exploratory analyses of individual differences in self-assessment. L2 Korean speakers (N = 198) self-assessed their…
