When acquiring the English plural, children correctly produce plural words long before they develop an understanding of morphological structure. When acquiring Sesotho noun prefixes, children are aware of the multiple constraints governing variation from a young age. Both of these cases raise questions about the Shin and Miller (2022) account of…

In this article, we provide an overview of the last twenty years of research on Indigenous sign languages, deaf community sign languages, co-speech gesture, and multimodal communication in the Australian context. From a global perspective, research on sign languages and on the gestures that normally accompany speech has been used as the basis for…

Historically, first language acquisition research was a painstaking process of observation, requiring the laborious hand coding of children's linguistic productions, followed by the generation of abstract theoretical proposals for how the developmental process unfolds. Recently, the ability to collect large-scale corpora of children's language…

This year's conference theme, "Be Seen, Be Heard," reflected not only our goal of celebrating our achievements but also represented our intent of making sure everyone's voices are heard, especially during 2017's difficult political climate. The conference opened with a motivating address from Dean Laura E. Lyons, followed by an…

Given that L1A of subject properties in non-null subject languages emerges later than that of null subject languages, this study aims at determining to what extent the same pattern of acquisition is observed in early child L2A in bilingual immersion settings where English and Spanish are both source and target languages. Using an elicited oral…

This study investigates how derivational complexity interacts with first language (L1) properties, second language (L2) input, age of first exposure to the target language, and length of exposure in child L2 acquisition. We compared elicited production of "wh"-questions in French in two groups of 15 participants each, one with L1 English…

The article by Amaral and Roeper (this issue; henceforth A&R) presents many interesting ideas about first and second language acquisition as well as some experimental data convincingly illustrating the difference between production and comprehension. The article extends the concept of Universal Bilingualism proposed in Roeper (1999) to second…

An area in need of study in child language acquisition is that of complex multilingual contexts in which there is little language separation by interlocutor or domain. Little is known about how multilingual children use language to construct their identities in each language or in both languages. Identity construction in monolingual contexts has…

With the ever increasing number of studies on formulaic language, we are beginning to learn more about the processing of formulaic language (e.g. Ellis et al. 2008; Siyanova et al. 2011), its use in speech (e.g. Aijmer 1996; Wood 2012) and writing (e.g. Hyland 2008a, 2008b) and its application in natural language processing (e.g. Tschichold 2000).…

Previous research has suggested that very young children learning English adhere quite rigidly to a grammatical constraint on the possible contexts for contraction of "want" and "to" into the reduced form "wanna". Two elicited production studies reported here suggest that young children do produce "wanna" in illicit contexts. One study identifies…

In her very interesting Keynote Article, Johanne Paradis gives a clear overview of recent research at the interface of bilingual development and child language disorders, and highlights its theoretical and clinical implications. She raises the challenging question of "whether bilingualism can be viewed as a kind of "therapy" for SLI." At first…

Joanne Paradis' Keynote Article on bilingualism and specific language impairment (SLI) is an impressive overview of research in language acquisition and language impairment. Studying different populations is crucial both for theorizing about language acquisition mechanisms, and for practical purposes of diagnosing and supporting children with…

Research at the interface of bilingual development and child language disorders has increased greatly in the past decade. The purpose of this article is to highlight the theoretical and clinical implications of this research. Studies examining the similarities in linguistic characteristics between typically developing sequential bilingual children…

What makes a child's language development trajectory have the patterns that it has, and what causes differences across children in those patterns? These fundamental questions have for over half a century been at the heart of research on language development in monolingual children, on the cross-linguistic development of language in children from…

Parents and child care personnel in English-dominant parts of the world often express misgivings about raising children bilingually. Their concerns are based on the belief that dual language learning during the infant-toddler stage confuses children, delays their development, and perhaps even results in reduced language competence. In this…
