I argue that the variation within and across contexts detailed by Shin & Miller is indicative of a broader phenomenon in which morphosyntax and the discourse context are intertwined, including elements like perspective, discourse relations, information structure, and common ground. Appealing to independent evidence highlighting the role of…

The well-known sampling limitation of most longitudinal corpus data can be even more consequential in the study of morphosyntactic variation in child language. An analysis of caregiver input suggests that variable use in overlapping contexts may be hard to find by solely relying on corpus data collected under the sampling procedures that are…

This article presents a developmental pathway for the acquisition of morphosyntactic variation. Although there is abundant evidence that morphosyntactic variation is pervasive among adults, much less is known about how children acquire such variation. The literature thus far indicates that the pathway of development involves first producing only…

This article examines whether children alter a variable phonological pattern in an artificial language towards a phonetically-natural form. We address acquisition of a variable rounding harmony pattern through the use of two artificial languages; one with dominant harmony pattern, and another with dominant non-harmony pattern. Overall, children…

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 study investigates children's identification of prosodic focus in Hungarian, a language in which syntactic focus-marking is mandatory. Assuming that regular syntactic focus-marking diminishes the disambiguating role of prosodic marking in acquisition, we expected that in sentences in which focus is only disambiguated by prosody, adult-like…

The development of the Multilingual Assessment Instrument for Narratives (MAIN) has no doubt contributed to prompting a renewed interest in children's narratives. This carefully controlled test of narrative abilities elicits a rich set of measures spanning multiple linguistic domains and their interaction, including lexis, morphosyntax,…

Purpose: This study examines the development of narrative microstructure elements of productivity, lexical diversity, and syntactic complexity in the oral story production of preschool- and school-age Kuwaiti Arabic-speaking children. It also explores the effects of story task complexity on the target microstructural features. Method: This study…

This study investigated Reading Recovery teacher understandings about language and early literacy acquisition by applying a constructivist grounded theory design. Participants were Reading Recovery teachers working across three varied districts in Massachusetts (N=33). The purpose of the study was to engage Reading Recovery teachers in surveys,…

English ditransitive verbs show a complex alternation between the double object construction (DOC, (1)) and prepositional object datives (POD, (2)). This dissertation examines the acquisition, representation, and learnability of the dative alternation among L2 English learners, presenting experimental data from participants with L1 backgrounds of…

Irish is a rapidly changing minority language spoken as the main community language in some areas of the officially Irish-speaking "Gaeltacht" regions in Ireland. We analyse narratives from 17 parent-child dyads, living in one such area. All children, aged 3-6;4, had high exposure to the local variety of Irish. The input quality was…

When learning a language, typically-developing infants face the daunting task of learning both the sounds and the meanings of words. In this dissertation, we focus on a source of variability that complicates the one-to-one relationship between words and their meanings: wordform variability. In Chapter 1 we make a distinction between the micro…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

Child language acquisition research has provided ample evidence of lexical frequency effects. This corpus-based analysis introduces a novel frequency measure shown to significantly constrain adult language variation, but heretofore unexplored in child language acquisition research. Among adults, frequent occurrence of a form in a particular…

Purpose: Language sample analysis is widely regarded as the gold standard of language assessment. However, the uncertainty regarding the optimal length of sample and the limited availability of developmental language data for nonmainstream languages such as Afrikaans complicate reliable use of the method. The study aimed to provide guidelines on…
