Upon hearing a novel label, listeners tend to assume that it refers to a novel, rather than a familiar object. While this disambiguation or mutual exclusivity (ME) effect has been robustly shown across development, it is unclear what it involves. Do listeners use their pragmatic and lexical knowledge to exclude the familiar object and thus select…

Verbs are often uttered before the events they describe. By 2 years of age, toddlers can learn from such an encounter. Hearing a novel verb in transitive sentences (e.g. "The boy lorped the cat"), even with no visual referent present, they later map it to a causative meaning (e.g. "feed") (e.g. Yuan & Fisher, [Yuan, S.,…

There is a debate as to whether topic structures in Chinese involve A'-movement or result from base-generation of the topic in the left periphery. If Chinese topicalization was derived by movement, under the assumptions of Friedmann et al.'s Relativized Minimality (Lingua 119:67-88, 2009), we would expect children's comprehension of object…

Previous studies report that children use color words haphazardly before acquiring conventional, adult-like meanings. The most common explanation for this is that children do not abstract color as a domain of linguistic meaning until several months after they begin producing color words, resulting in a stage during which they produce but do not…

When learning verb meanings, learners capitalize on universal linguistic correspondences between syntactic and semantic structure. For instance, upon hearing the transitive sentence "the boy is glorping the girl," 2-year-olds prefer a two-participant event (e.g., a boy making a girl spin) over two simultaneous one-participant events (a…

The purpose of this study was to examine early fast mapping abilities in late talkers (LT) and typically developing (TD) Spanish-speaking children by considering the effect of different variables on fast mapping (age, vocabulary level, grammatical category and number morphology). Thirty-eight Spanish-speaking children were assessed at three times…

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better…

Syntactic bootstrapping facilitates children's initial learning of verb meanings based on syntactic information. A challenging case is the argument-drop languages, where the number of argument NPs is not a reliable cue for distinguishing between transitive and intransitive verbs. Despite this fact, the availability of syntactic bootstrapping in…

This study investigated whether vocabulary delays in toddlers with autism spectrum disorders (ASD) can be explained by a cognitive style that prioritizes processing of detailed, local features of input over global contextual integration--as claimed by the weak central coherence (WCC) theory. Thirty toddlers with ASD and 30 younger,…

Grammatical gender embedded in determiners, nouns and adjectives allows indirect and more rapid processing of the referents implied in sentences. However in a language such as Spanish, this useful information cannot be reliably retrieved from a single source of information. Instead, noun gender may be extracted either from phono-morphological,…

Using an observational task followed by an experimental task with an Intermodal Preferential Looking Paradigm, we examined the effect of input on children's acquisition of class extension rules by investigating the relationship between the amount of polysemous noun-verb pairs in French-speaking 2-year-olds' input and both their spontaneous…

We trained forty German-speaking children aged 1;8-2;0 in their comprehension of UNTER [UNDER]. The target word was presented within semantically organized input in the form of a "narrative" to the experimental group and within "unconnected speech" to the control group. We tested children's learning by asking them to…

The correct use of an affix, such as the English plural suffix, may reflect mastery of a morphological process, but it may also depend on children's syntactic, semantic, and phonological abilities. The present article reports a set of experiments in support of this latter view, specifically focusing on the importance of the phonological make-up of…

This paper investigated children's ability to use syntactic structures to infer semantic information. The particular syntax-semantics link examined was the one between transitivity (transitive/intransitive structures) and telicity (telic/atelic perspectives; that is, boundedness). Although transitivity is an important syntactic reflex of telicity,…
