The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with…

We studied English-learning children's ability to learn the meanings of novel words from sentences containing truth-functional negation (Exp1) and to use the semantics of negation to inform word meaning (Exp2). In Exp1, 22-month-olds (n = 21) heard dialogues introducing a novel verb in either negative-transitive "("Mary didn't blick the…

In English, the sentence "Mary didn't eat pizza or sushi" is assigned the "neither interpretation" (both disjuncts must be false). In Mandarin Chinese, the equivalent sentence is assigned the at least one interpretation (at least one disjunct must be false). The cross-linguistic variation in the interpretation of negative…

Children have been reported to prefer the surface scope or "isomorphic" reading of scopally ambiguous sentences (Musolino 1998, among others). Existing accounts in the literature differ with respect to the proposed source of this "isomorphism effect." Some accounts are based on learnability considerations (e.g., Moscati &…

Sentences involving definite DPs can give rise to a "simultaneous" reading where the property expressed by the DP holds at the time introduced by the verb's tense or an "indexical" reading where the property expressed by the DP holds at the utterance time. This article discusses an experiment showing that children prefer…

The current study examined preschool children's ability to evaluate the entailment patterns yielded by sentences containing two downward entailing (DE) operators, "every" and "no." When "no" precedes "every," the entailment pattern typically licensed by "every" changes, but only if "no"…
