The cross-overs between monolingual-bilingual and typically atypically developing children are a goldmine for research on language development. The four permutations of language exposure and language abilities create "natural experimental conditions" for investigating the nature of the language capacity and how this is shaped by input in typical…

Korean writing is a syllabary where spaces occur between phrases rather than between words. This characteristic of Korean allows different types of information in Korean sentences to be dissociated in ways that are not possible in the languages that have been the focus of most psycholinguistic research, thereby providing new opportunities to…

We show that 4-year-olds assign the correct interpretation to antecedent-contained deletion (ACD) sentences because they have the correct representation of these structures. This representation involves Quantifier Raising (QR) of a Quantificational Noun Phrase (QNP) that must move out of the site of the verb phrase in which it is contained to…

Because words represent the building blocks upon which the facility to produce and comprehend language at all levels is based, the capacity of a child to learn words has immense impact on his or her developing abilities to communicate and engage properly with the outside world. Both the Keynote Article and the Commentaries in this issue…

We present a set-theoretic model of the mental representation of classically quantified sentences (All P are Q, Some P are Q, Some P are not Q, and No P are Q). We take inclusion, exclusion, and their negations to be primitive concepts. We show that although these sentences are known to have a diagrammatic expression (in the form of the Gergonne…
