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 Arabic verb system features a nonlinear root and pattern derivational morphology. Previous studies suggest that young Arabic and Hebrew speakers' early verb use is based on semantic complexity rather than derivational morphological structure. The present study examines the role of morphological and semantic complexity in the emergence…

Support (one object preventing another from falling) is linguistically encoded by adults and children in a highly structured and differentiated way, with basic locative expressions or Light verbs (e.g., in English, the block is "on/put" on the box) encoding Support-from-Below, and lexical verbs (e.g., she "stuck" the block on…

This research examined how linguistic differences between African American English (AAE) and Mainstream American English (MAE) impact how children process sentences and learn new information. The central hypothesis of this dissertation is that these linguistic differences adversely impact how AAE-speaking children use contrastive inflectional verb…

Adopting the framework of projection from Systemic Functional Linguistics, the present study explored the deployment of projection in summary writing by three levels of college EFL learners from a university in mainland China. Data were collected from one summary writing by three classes of different levels' learners in an English program from a…

The delayed acquisition of Spanish "ser" and "estar" is generally understood as rooted in the cognitive demands imposed by the integration of semantic-pragmatic and world-knowledge factors associated with their lexical meanings. Here we ask (1) what is the nature of this language world-knowledge integration? and (2) what is the…

Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to L[subscript B] once the L[subscript A]…

This study investigates the influences of early and intense L2 exposure on children's L1 causative verb production, assessed by an experimental causative verb production task. Turkish expresses causality by morphological and lexical means, whereas English does so by periphrastic and lexical means. Learning L2 English might enhance L1 Turkish…

The acquisition of voice in Greek remains understudied, especially in heritage populations. Voice in Greek poses a challenging acquisition task for children due to its syncretism, marking various verb classes as well as passives. The present study explores the acquisition of anticausatives, reflexives, and passives in 6-to-8-year-old monolingual…

Data from elicited language tasks can add to the literature on the development of the complex syntax structures of embedded complement clauses in typically developing children. In the current study, preschool-age children (n = 27) participated in two elicited language tasks focusing on three types of embedded complement clauses: infinitival…

While semantic and syntactic properties of verb meaning can impact the success of verb learning at a single age, developmental changes in how these factors influence acquisition are largely unexplored. We ask whether the impact of syntactic and semantic properties on verb vocabulary development varies with age and language ability for toddlers…

Children show a remarkable degree of consistency in learning some words earlier than others. What patterns of word usage predict variations among words in age of acquisition? We use distributional analysis of a naturalistic corpus of child-directed speech to create quantitative features representing natural variability in word contexts. We…

Perception verbs and mental verbs have significant overlap in their syntax and semantics; both reference mental representations when taking embedded clauses, as in "I see that Maria was here" and "I think that Maria was here." Some have suggested that perception is more accessible for young children than mental states, raising…

Purpose: This study examines the effect of age on language use with an automated analysis of digitized speech obtained from semistructured, narrative speech samples. Method: We examined the Cookie Theft picture descriptions produced by 37 older and 76 young healthy participants. Using modern natural language processing and automatic speech…

English contains a considerable number of lexical combinations with various forms and labels, making it an interesting field of inquiry for researchers. The significance and popularity of support verb constructions (SVC) is that they are used largely by native speakers and include some of the most common words in English but seem to be problematic…
