Children with disabilities and developmental delays (DD) often face challenges within education systems, which are typically unprepared to meet their language needs nor equipped to support bilingualism because of the current early intervention (EI) workforce. Given this, the five-language domains framework can help bilingual EI educators to…

When toddlers view an event while hearing a novel verb, the verb's syntactic context has been shown to help them identify its meaning. The current work takes this finding one step further to reveal that even in the absence of an accompanying event, syntactic information supports toddlers' identification of verb meaning. Two-year-olds were first…

This paper sets out to show how facilitation between different clause structures operates over time in syntax acquisition. The phenomenon of facilitation within given structures has been widely documented, yet inter-structure facilitation has rarely been reported so far. Our findings are based on the naturalistic production corpora of six toddlers…

Childers and Tomasello (2001) found that training 2 1/2-year-olds on the English transitive construction greatly improves their performance on a post-test in which they must use novel verbs in that construction. In the current study, we replicated Childers and Tomasello's finding, but using a much lower frequency of transitive verbs and models in…

This article reports on a series of 5 analyses of spontaneous production of verbal inflection (tense and person-number agreement) by 2-year-olds acquiring French as a native language. A formal analysis of the qualitative and quantitative results is developed using the unique resources of Optimality Theory (OT; Prince & Smolensky, 2004). It is…

This study investigated the earliest manifestations of verb tense and agreement in English-speaking children, using longitudinal data on the language of four children aged 1:6 to 3:5 years, drawn from a child-language database. Analysis focused on one aspect of inflectional phrase (IP), the children's use of the verbs "be" and "do" forms to mark…
