This paper provides fresh insights on how PIs (Polarity Items) in non-veridical contexts (questions and conditionals) are represented in the grammar of multilingual learners of Catalan at different stages of development. It explores how this non-native grammatical system interacts with other previously acquired systems of negation and the implicit…

Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

The ability to objectively quantify the complexity of a text can be a useful indicator of how likely learners of a given level will comprehend it. Before creating more complex models of assessing text difficulty, the basic building block of a text consists of words and, inherently, its overall difficulty is greatly influenced by the complexity of…

Many languages encode phi-features via overt morphology, yet children's use of this morphology in comprehension tasks varies widely. Here, we use a picture-selection task to test comprehension of Spanish verbal agreement and clitics, comparing performance across and within each paradigm to examine the effect of two factors: (i) phonological…

A surprising comprehension-production asymmetry in subject-verb (SV) agreement acquisition has been suggested in the literature, and recent research indicates that task-specific as well as language-specific features may contribute to this apparent asymmetry across languages. The present study investigates when during development children acquiring…

The present study focuses on the development of Spanish pronominal processing. We investigate whether the "pronoun interpretation problem" (i.e., reflexive pronouns comprehension is resolved at an earlier age than that of personal pronouns, also known as the "Delay of the Principle B Effect"), which has been documented in other…

In bilingual language environments, infants and toddlers listen to two separate languages during the same key years that monolingual children listen to just one and bilinguals rarely learn each of their two languages at the same rate. Learning to understand language requires them to cope with challenges not found in monolingual input, notably the…

How do early bilingual experiences influence children's neural architecture for word processing? Dual language acquisition can yield common influences that may be shared across different bilingual groups, as well as language-specific influences stemming from a given language pairing. To investigate these effects, we examined bilingual English…

Oral language abilities have been reported to be related to reading development. This relationship seems to be determined by orthographic systems and reading development. Children with developmental language disorder (DLD) show reading difficulties, although most studies focus on reading comprehension. The present study has two main objectives: to…

Previous research indicates that the development of mood selection in Spanish spans several years and ends in the mastery of mood selection with sentential complements to express complex semantic meanings. The present study investigates this underexplored late stage by examining how Spanish-speaking children acquire adultlike mood selection in…

The present study is designed to investigate whether children's difficulties with subject-to-subject raising (StSR) are due to intervention effects. We examine English-speaking children's comprehension of StSR with "seem" and Spanish-speaking children's comprehension of StSR with "parecer" 'seem,' a configuration never before…

Quantificational elements such as some pose a challenge to young language learners, given their vague meaning and ability to take on an upper-bounded interpretation (relative to "all") in certain contexts. The challenge is enhanced when a child is acquiring multiple languages that do not share a one-to-one mapping between their lexical…

The present study examines how second language learners (L2) assign the thematic roles of agent/patient in Spanish passive sentences with "ser" (often referred to as the true passive) when it is their initial exposure to this structure. The target sentences were preceded by a contextual sentence. After hearing the two sentences,…

Many Latino children in the U.S. speak primarily Spanish at home with few opportunities for exposure to English before entering school. For monolingual children, the strongest early predictor of later school success is oral language skill developed before kindergarten. Less is known about how early oral language skills support later learning in…

Purpose: This experiment examined English- or Spanish-learning preverbal (8-9 months, n = 32) and postverbal (12-14 months, n = 40) infants' learning of word-action pairings prior to and after the transition to verb comprehension and its relation to naturally learned vocabulary. Method: Infants of both verbal levels were first habituated to 2…
