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…

This article investigates infant comprehension of filler-gap dependencies. Three experiments probe 15- and 20-month-olds' comprehension of two filler-gap dependencies: "wh"-questions and relative clauses. Experiment 1 shows that both age groups appear to comprehend "wh"-questions. Experiment 2 shows that only the younger…

In this article we offer up a particular linguistic phenomenon, quantifier-variable binding in Kannada ditransitives, as a proving ground upon which competing claims about learnability can be evaluated with respect to the relative abstractness of children's grammatical knowledge. We first identify one aspect of syntactic representation that…

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…

Theories of indefinites vary with respect to whether these noun phrases can be treated as quantificational. Although everyone seems to be in agreement that indefinites do not always introduce their own quantificational force, there is widespread disagreement as to whether they ever do. In this article, we present experimental evidence from…
