Event segmentation tests have shown substantial overlaps in how adults recognize starts and endpoints as events unfold. However, far less is known about what role different language systems play in the process. Variations in grammatical aspect have been shown to influence event processing. We tested how closely first language (L1) speakers of…

Over the last two decades, the question of to which linguistic cues learners pay attention when they decode a new language has been subject to controversy in the field of third language (L3) acquisition. In this article, we present an artificial language learning experiment that investigated how lexical and syntactic similarities between an…

This study examined the influence of cognate status and language distance on simultaneous bilingual children's vocabulary acquisition. It aimed to tease apart effects of word-level similarities and language-level similarities, while also exploring the role of individual-level variation in age, exposure, and nontarget language proficiency. Children…

Although several studies have focused on novel word learning and lexicalization in (presumably) monolingual speakers, less is known about how bilinguals add novel words to their mental lexicon. In this study we trained 33 English-French bilinguals on novel word-forms that were neighbors to English words with no existing neighbors. The number of…

This study extended an existing crosslinguistic model of verb-marking errors in children's early multiword speech (MOSAIC) by adding a novel mechanism that defaults to the most frequent form of the verb where this accounts for a high proportion of forms in the input. Our simulations showed that the resulting model not only provides a better…

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…

We investigated the role of cue weighting, second language (L2) proficiency, and L2 daily exposure in L2 learning of suprasegmentals different from the first language (L1), using eye-tracking. Spanish monolinguals, English-Spanish learners, and Mandarin--Spanish learners saw a paroxytone and an oxytone verb (e.g., "FIRma-firMÓ"…

Second language (L2) learners make gender errors with possessive pronouns. In production, these errors are modulated by the gender match between the possessor and possessee noun. We examined whether this so-called match effect extends to L2 comprehension by attempting to replicate a recent study on gender predictions in first language (L1) German…

Several previous studies showed that prime-target pairs with orthographical overlap but no semantic or morphological relationship (e.g., freeze-free) produced a masked priming effect in second language (L2) speakers but not in first language (L1) speakers. The present study further explored this intriguing L1-L2 difference by comparing English…

Recent research has shown that knowledge of second language (L2) collocations is important to learners for improving their language processing and production but also that acquiring L2-specific collocations is a very burdensome task for learners. Thus, bootstrapping knowledge of L2 collocations through generalization is highly desirable, but this…

This article focuses on the role of crosslinguistic patterns with verbs in the mapping of noun phrases/semantic roles to positions in morphosyntax, with a particular focus on second language (L2) development of Spanish "se." The data set derives from high school learners of Spanish in the United States under broadly deductive and…

Some second language (L2) acquisition researchers have suggested that learners should be made aware of cross-linguistic similarity for them to benefit from cognateness. To test this assumption, we ran two longitudinal classroom quasi-experiments with Polish learners of English. We chose 30 Polish-English cognates, 30 false cognates, and 30…

Research has shown that contoids (phonetically defined consonants) may provide more robust and reliable cues to syllable and word boundaries than vocoids (phonetically defined vowels). Recent studies of Danish, a language characterized by frequent long sequences of vocoids in speech, have suggested that the reduced occurrence of contoids may make…

This study examined the acquisition of preposition placement in English as a second language from a usage-based perspective. German and Chinese learners of English and English native speakers rated the acceptability of English oblique "wh" relative clauses in a magnitude estimation task. Results indicated that acceptability depended on…

Languages often use different constructions to convey the same meaning. For example, the meaning of a causative construction in English ("Jen had her computer fixed") is conveyed using an active structure in Korean ("Jen-NOM her computer-ACC fixed"), and yet little is known about how bilinguals represent and process such…
