Young children can exploit the syntactic context of a novel word to narrow down its probable meaning. This is "syntactic bootstrapping." A learner that uses syntactic bootstrapping to foster lexical acquisition must first have identified the semantic information that a syntactic context provides. Based on the "semantic seed…

Non-adult-like linguistic behavior in children is sometimes taken as evidence for endogenous factors that drive selection of grammatical features from the child's hypothesis space of possible grammars. Analyses of English-acquiring children's productions of medial "wh"-phrases exemplify this trend in particular. We provide an alternative…

Research on second-language (L2) acquisition has identified linguistic domains that appear to be especially difficult to learn--one such sticking point being syntactic structures that depend on the surrounding discourse. The Interface Hypothesis (IH) explains what makes such constructions problematic by appealing to a modular view of language,…

This project examines whether second-language (L2) learners can converge on a native-like pattern at the interface between syntax and discourse under low and high processing pressure, using Spanish clitic-doubled left dislocation (CLLD) as a test case. The original version of the Interface Hypothesis (IH) predicts that L2 competence on…

This study investigates L2 learners' ability to use morphosyntactic gender as a predictive cue during the processing of Hindi agreement dependencies. Nine L2 learners of low-intermediate proficiency and nine highly proficient multilingual speakers who consider Hindi one of their dominant languages were tested using a speeded picture-selection…

It is a common finding across languages that young children have problems in understanding patient-initial sentences. We used Tagalog, a verb-initial language with a reliable voice-marking system and highly frequent patient voice constructions, to test the predictions of several accounts that have been proposed to explain this difficulty: the…

To test between two recent accounts of the early stages in the acquisition of negation, we conducted an elicited production study with 25 children, between 2;05 and 3;04 (mean 2;11). The experimental study produced a robust set of negative sentences, with considerable individual variation. Although 13 of the child participants mainly produced…

It is by now well established that toddlers use the linguistic context in which a new word--and particularly a new verb--appears to discover aspects of its meaning. But what aspects of the linguistic context are most useful? To begin to investigate this, we ask how 2-year-olds use two sources of linguistic information that are known to be useful…

We compare the predictions of two different accounts of first language acquisition by investigating the relative contributions of abstract syntax and input frequency to the elicited production of main and embedded questions by 36 monolingual English-speaking toddlers aged 3;00 to 5;11. In particular, we investigate whether children's accuracy…

We argue that the debate over the delay of Principle B effects needs to include an additional class of contexts: Evans-style or Exceptional Coreference contexts (ECCs) (e.g., "It's not true that no one voted for John. John[subscript 1] voted for him[subscript 1]"). Our experiment compares acquisition of regular Principle B contexts (B-contexts)…

Twenty-five monolingual (L1) children with specific language impairment (SLI), 32 sequential bilingual (L2) children, and 29 L1 controls completed the Test of Active & Passive Sentences-Revised (van der Lely 1996) and the Self-Paced Listening Task with Picture Verification for actives and passives (Marinis 2007). These revealed important…

This paper examines two issues concerning nonagreeing "don't" in child English, e.g., "He don't fit". (1) Do children know that "don't" consists of auxiliary "do" plus sentential negation, or do they misanalyze it simply as negation? I argue that the former claim yields both empirical (distributional) and conceptual advantages, while the latter…

This study examined the existence of an object omission stage and the interaction between object omissions and substitution errors in the early stages of the development of Spanish syntax. One hundred and three Spanish-speaking children from Colombia completed an elicitation task evaluating the production of direct object pronouns. Results…
