Purpose: Following the Rehabilitation Treatment Specification System (RTSS) framework, the current study investigated the active ingredients in the modified semantic feature analysis (mSFA) targeting either noun or verb retrieval in Mandarin-English bilingual adults with aphasia (BWA). Method: Twelve Mandarin-English BWA completed mSFA treatment…

When infants hear sentences containing unfamiliar words, are some language-world links (such as noun-object) more readily formed than others (verb-predicate)? We examined English learning 14-15-month-olds' capacity for linking referents in scenes with bisyllabic nonce utterances. Each of the two syllables referred either to the object's identity,…

Verb-marking errors such as "she play football" and "daddy singing" are a hallmark feature of English-speaking children's speech. We investigated the proposal that these errors are input-driven errors of commission arising from the high relative frequency of subject + unmarked verb sequences in well-formed child-directed…

Language is one of the essential tools used to segment the continuous stream of experience into events. In this process, the choice of words and grammar frames events in different ways. Grammatical aspect plays an important role in representing an event as a complete whole (perfective: peeled) or as a dynamic process (imperfective: was peeling).…

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…

To learn new words, particularly verbs, child learners have been shown to benefit from the linguistic contexts in which the words appear. However, cross-linguistic differences affect how this process unfolds. One previous study found that children's abilities to learn a new verb differed across Korean and English as a function of the sentence in…

Through consultations with the online version of the Longman Dictionary of Contemporary English (LDOCE) and the Corpus of Contemporary American English (COCA), this study focuses on distinguishing between the two synonymous verbs "restrict" and "constrain," both part of Coxhead's (2000) Academic Word List, in terms of formality…

Words that describe sensory perception give insight into how language mediates human experience, and the acquisition of these words is one way to examine how we learn to categorize and communicate sensation. We examine the differential predictions of the typological prevalence hypothesis and embodiment hypothesis regarding the acquisition of…

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: Within General American English (GAE), the grammar weaknesses of children with developmental language disorder (DLD) have been documented with many tasks, including grammaticality judgments. Recently, Vaughn et al. replicated this finding with a judgment task targeting tense and agreement (T/A) structures for children who spoke African…

Three case-studies, using longitudinal records of children's spontaneous speech, illustrate what happens when a child's syntax changes. The first, examining acquisition of English verb-particle constructions, shows a near-total absence of commission errors. The second, examining acquisition of prepositional questions in English or Spanish, shows…

All accounts of language acquisition agree that, by around age 4, children's knowledge of grammatical constructions is abstract, rather than tied solely to individual lexical items. The aim of the present research was to investigate, focusing on the passive, whether children's and adults' performance is additionally semantically constrained,…

The purpose of this study was to consider the core of the mental lexicon of the Kazakh language based on the analysis of associative dictionaries, to determine the basic lexico-semantic groups of words and to compare the basic lexical layer with value categories. This study uses the following methods of linguocultural, comparative,…

Background: Parental input plays a central role in typical language acquisition and development. In autism spectrum disorder (ASD), characterized by social communicative and language difficulties, parental input presents an important avenue for investigation as a target for intervention. A rich body of literature has identified which aspects 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…
