This meta-analysis synthesized 35 English studies (130 effect sizes, N = 1,981) that employed online tasks to investigate the processing of multiword sequences (MWSs). We examined (a) to what extent MWSs enjoy a processing advantage over novel word combinations; (b) how such a processing advantage is moderated by statistical regularities (i.e.,…

This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and…

While monolingual speakers can use contrastive pitch accents to predict upcoming referents, bilingual speakers do not always use this cue predictively in their L2. The current study examines the role of recent exposure for predictive processing in native German (L1) second language learners of English (L2). In Experiment 1, participants followed…

For more than a decade, research on heritage speakers' (HSs') mood selection has documented a high degree of variability in their interpretation and use of mood morphology in variable contexts. Most of the previous literature, however, has focused on late-acquired alternations, and often limited analyses to one form (i.e., subjunctive), making it…

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,…

Despite extensive theoretical and empirical research, we do not have estimations of the magnitude of sensitivity to grammatical information during L2 online processing. This is largely due to reliance on null hypothesis significance testing (Plonsky, 2015). The current meta-analysis draws on data from one elicitation technique, self-paced reading,…

This article investigates how lexical and syntactic differences in L1 and L2 grammatical gender affect L2 predictive gender processing. In a visual-world eye-tracking experiment, 24 L1 Russian adult learners and 15 native speakers of German were tested. Both Russian and German have three gender classes. Yet, they differ in lexical congruency, that…

We test the interpretation of pronominal forms in L2 speakers of English whose L1 is Spanish. Previous research on learners of nonnull subject languages has shown conflicting results. The aim of the present study is to reconcile previous evidence and shed light on the factors that determine learners' difficulty to interpret pronominal forms in the…

A number of longitudinal studies of L2 production have reported frequency effects wherein learners' produce more frequent words as a function of time. The current study investigated the spoken output of English L2 learners over a four-month period of time using both native and non-native English speaker frequency norms for both word types and word…

Based on writing produced by second language learners at different proficiency levels (CEFR A1 to C1), we adopted a usage-based approach (Ellis, Römer, & O'Donnell, 2016; Tyler & Ortega, 2018) to investigate how German and Spanish learner knowledge of 19 English verb-argument constructions (VACs; e.g., "V with n," illustrated by…

Numerous studies have demonstrated that native Mandarin speakers have pervasive difficulties processing L2 English agreement morphology. However, less is known about the lexical and morphological cues that may modulate Mandarin speakers' sensitivity to English number agreement. To investigate this, we examined subject-verb agreement processing in…

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…

We document weak garden paths after intransitive verbs, modulated by intransitivity type, in the treatment of DP[subscript 1] V[subscript intransitive] DP[subscript 2] V[subscript 2] sequences as in "As the journalist arrived the editor postponed the meeting" in first language (L1) and second language (L2) sentence processing. In a…

This paper presents an experimental study of the rarely explored question of how input through instruction interacts with L2 acquisition at the level of modular linguistic knowledge. The investigation focuses on L2 knowledge of the English polarity item "any," whose properties are only partially covered by typical language-teaching…

This study investigated the influence of frequency effects on the processing of congruent (i.e., having an equivalent first language [L1] construction) collocations and incongruent (i.e., not having an equivalent L1 construction) collocations in a second language (L2). An acceptability judgment task was administered to native and advanced…
