The dissertation presents a pioneering investigation into child speech among Bikolano children. It aims to address the underdescription and underdocumentation of Child Bikol as spoken in the Philippines. Bikol, an Austronesian macrolanguage, often coexists with more dominant languages, making Bikolano children both emergent multilinguals and…

There is a growing body of research from various perspectives in heritage language (henceforth HL) acquisition as an emerging field. Some studies proposed that HL acquisition is a differential acquisition compared with the baseline language (i.e., the language spoken by the parents or caregivers) (Kupisch & Rothman, 2018; Dubiel &…

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…

This study is based on naturalistic speech samples produced by one child learning Cree as her first language (2;01-4;03) and presents the first investigation into the development of preverbs in the language. Preverbs are an optional class of morpheme which precede the lexical verb stem, dividing into grammatical, lexical and directional (deictic)…

Previous research on the L1 acquisition of motion event expression suggests that mapping multiple semantic components onto syntactic units is associated with greater difficulties in verb-framed than in satellite-framed languages, because the former require more complex structures (using subordination). This study investigated the impact of this…

This project examined the acquisition of third person accusative clitics in Spanish by Chinese-speaking learners. Specifically, it focused on the role of cross-linguistic influence and patterns of language exposure and use in the acquisition of the syntactic and semantic properties constraining the production and intuition of overt and null…

This study investigates for the first time the comprehension of rhetorical questions (RhQs) in bilingual children. RhQs are non-canonical questions, as they are not used to request information, but to express the speaker's belief that the answer is already obvious. This special pragmatic meaning often arises by means of specific prosodic and…

The linguistic interdependence hypothesis posits the existence of language features common to different languages. This set of characteristics, known as Common Underlying Proficiency (CUP), is a powerful facilitating agent in second language acquisition. Fluid intelligence (Gf), on the other hand, is the construct that encompasses those cognitive…

Universals in natural language have long been a focus of the generative syntactic and typological literature. However, the source of these universals is not clear. Within Chomskyan generative syntactic literature, it is assumed that children are endowed with innate knowledge of language structure (see for example, Lightfoot 1999). However,…

Constructivist approaches to language acquisition predict that form-function mappings are derived from distributional patterns in the input, and their contextual embedding. This requires a detailed analysis of the input, and the integration of information from different contingencies. Regarding the acquisition of morphology, it is shown which…

Studies that measure the effectiveness of language-training program for children's language development do not clearly identify in adult-child interaction which characteristics of educators' language are most effective, particularly for children over 4 years of age who need to develop complex syntactic skills. Our study aimed to analyze the…

Negation is a cornerstone of human language and one of the few universals found in all languages. Without negation, neither categorization nor efficient communication would be possible. Languages, however, differ remarkably in how they express negation. It is yet widely unknown how the way negation is marked influences the acquisition process of…

Languages vary according to which morphosyntactic forms of embedding are present in the grammar as well as to which of these forms allow recursive embedding. The present study examines how German-speaking children discover which forms of embedding are recursive. In German, possessive modifiers are expressed by several structural options (i.e.,…

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…

Previous studies show that infants store functional morphemes for inferring syntactic categories of adjacent words, and they generally perform better with nouns than with verbs. In this study, we tested whether toddlers can exploit phrasal groupings for syntactic categorization in the face of noisy co-occurrence patterns. Using a visual fixation…
