How can syntactic and learnability analyses inform each other, and thus deepen our understanding of syntax and its acquisition? This dissertation illuminates this question through three case studies in Korean syntax. I examine cases in which two structures that display distinct syntactic properties share extremely similar surface forms, thus…

Purpose: Production of complex syntax is a hallmark of later language development; however, most of the research examining age-related changes has focused on adolescents or analyzed narrative language samples. Research documenting age-related changes in the production of complex syntax in elementary school-aged children in conversational language…

Purpose: The purpose of this study is to determine if 2.5-year-olds with language delay would learn verbs ("spill") when presented with varying syntactic structure ("The woman is spilling the milk"/"The milk is spilling"; "milk" = patient or theme) in a therapeutic context. Children with language delay have…

A B S T R A CT Purpose: Retrieval practice has been shown to assist the word learning of children with developmental language disorder (DLD). Although this has been true for learning new verbs as well as new nouns and adjectives, these children's overall verb learning has remained quite low. In this preregistered study, we presented novel verbs in…

Purpose: Children with developmental language disorder (DLD) tend to interpret noncanonical sentences like passives using event probability (EP) information regardless of structure (e.g., by interpreting "The dog was chased by the squirrel" as "The dog chased the squirrel"). Verbs are a major source of EP information in adults…

How do children infer the meaning of a novel verb? One prominent proposal is that children rely on syntactic information in the linguistic context, a phenomenon known as "syntactic bootstrapping". For example, given the sentence "The bunny is gorping the duck," a child could use knowledge of English syntactic roles to infer…

Memory limitations and probabilistic expectations are two key factors that have been posited to play a role in the incremental processing of natural language. Relative clauses (RCs) have long served as a key proving ground for such theories of language processing. Across three self-paced reading experiments, we test the online comprehension of…

The study investigates whether Italian verbal inflectional morphology is associated with inhibitory control skills after controlling for receptive vocabulary and verbal working memory. A sample of Italian preschoolers aged 4;0 to 6;0 was assessed using a standardized inhibitory control task tapping two different inhibitory skills (response…

Based on the bilingual children's and adults' code-switching (CS) dependency treebanks, this paper investigates the syntactic features and pragmatic functions of the Chinese-English bilingual children's CS and compares them with bilingual adults'. It is mainly found that (1) As to the bilingual children, the mixed sentences present the longest…

Verb-marking errors are a characteristic feature of the speech of typically-developing (TD) children and are particularly prevalent in the speech of children with Developmental Language Disorder (DLD). However, both the pattern of verb-marking error in TD children and the pattern of verb-marking deficit in DLD vary across languages and interact…

In this dissertation I investigate the Mandarin "you"-existential sentence. My focus is on its syntax. I also discuss in less detail some semantic peculiarity of the "you"-existential. I begin my investigation of the syntax of "you"-existentials by first looking into what they are not. To this end, I present five…

Purpose: Pronouns are referentially ambiguous: For example, "she" could refer to any female. Nonetheless, errors in pronoun interpretation rarely occur for adults with typical development (TD) due to several strategies implicitly shared between the talker and listener. The purpose of this study was to test the impacts of syntactic,…

This case study describes the use of a syntax intervention with two deaf children who did not acquire a complete first language (L1) from birth. It looks specifically at their ability to produce subject-verb-object (SVO) sentence structure in American Sign Language (ASL) after receiving intervention. This was an exploratory case study in which…

We present a visual world eye-tracking study on Tseltal (a Mayan language) and investigate whether verbal information can be used to anticipate an upcoming referent. Basic word order in transitive sentences in Tseltal is Verb--Object--Subject (VOS). The verb is usually encountered first, making argument structure and syntactic information…

The purpose of this study was to compare the types of morphological and syntactic errors in written simple and complex sentences produced by children with developmental language disorder (DLD) and children with typical language (TL). We analyzed the writing products of 30 children with DLD and 33 children with TL for morphological (e.g., past…
