It has been proposed that an implicit learning deficit explains the difficulties with grammar commonly observed in children with Developmental Language Disorder (DLD). The present study further investigates this link in two ways. Firstly, we investigate whether kindergartners with DLD have more difficulties with preposition understanding and…

This paper explores the nature of copula omission in Cypriot Greek individuals with Down Syndrome (DS). Previous studies on DS have attributed high rates of copula omission to an overall grammatical/inflectional impairment without offering further analysis. In order to identify relevant conditioning factors, we examined copula productions and…

Visually situated spoken words activate phonological, visual, and semantic representations guiding overt attention during visual exploration. We compared the activation of these representations in children with and without developmental language disorder (DLD) across four eye-tracking experiments, with a particular focus on visual (shape)…

In English, a sentence like "The cat didn't eat the carrot or the pepper" typically receives a "neither" interpretation; in Japanese it receives a "not this or not that" interpretation. These two interpretations are in a subset/superset relation, such that the "neither" interpretation (strong reading)…

When reading Chinese, skilled native readers regularly gain a preview benefit (PB) when the parafoveal word is orthographically or semantically related to the target word. Evidence shows that non-native, beginning Chinese readers can obtain an orthographic PB during Chinese reading, which indicates the parafoveal processing of low-level visual…

This study investigates the role of emotional linguistic input in learning novel words with abstract and concrete denotations. It is widely accepted that concrete words are processed more easily than abstract ones. Several theories of vocabulary acquisition additionally propose a critical role of sensorimotor and emotional information during novel…

This paper reports an experiment that investigates interpretive distinctions between two different expressions of generalization in Spanish. In particular, our aim was to find out when the distinction between generic statements (GS) such as "Tigers have stripes" and universally quantified statements (UQS) such as "All tigers have…

How does linguistic structure affect children's developing cardinal number knowledge? The bootstrapping theory proposes that children might use syntactic information provided by known words such as quantifiers to bootstrap the meanings of unfamiliar words such as number words. Prior studies of numeral and quantifier development have indicated that…

Recently, researchers interested in the nature and origins of semantic representations have investigated an especially informative case study: The acquisition of the word "most"--a quantifier which by all accounts demands a sophisticated second-order logic, and which therefore poses an interesting challenge to theories of language…

Children acquire argument structure through distributional evidence, but how does this interacts with event semantics and existing verb knowledge? The current study compares verb learning in adult speakers of Japanese (where lexical causatives span wider semantic categories) and English (where alternation is more restricted). In the Fully…

The acquisition of a new morphological rule can be influenced by numerous factors, including the type of feedback provided during learning. The present study aimed to test the effect of different feedback types on children's ability to learn and generalize an artificial morphological rule (AMR). Two groups of eight-year-olds learned to judge and…

This study investigated age differences in the utilization of visually contrastive information (i.e., differently colored identical objects) for temporary referential ambiguity resolution during spoken sentence comprehension. Five- and 6-year-old Japanese children and adults listened to sentences that contained a color adjective-noun combination…

Previous studies have demonstrated that, for adults, differences between unaccusative verbs (e.g., "fall") and unergative verbs (e.g., "dance") lead to a difference in processing. However, so far we don't know whether this effect shows up in children's processing of these verbs as well. This study measures children's processing…

How do children infer the meaning of a word? Current accounts of word learning assume that children expect a word to map onto exactly one concept whose members form a coherent category. If this assumption was strictly true, children should infer that a homophone, such as "bat," refers to a single superordinate category that encompasses…

Negative sentences with epistemic modals (e.g., John "might" not come/John "can" not come) contain two logical operators, negation and the modal, which yields a potential semantic ambiguity depending on scope assignment. The two possible readings are in a subset/superset relation, such that the strong reading ("can…
