Title: Interactin of negation and universal quantification in the grammar of 4-year-olds
Time: Friday, November 15th, 2pm – 3pm
Location: 32-D461

Abstract: Aravind et al (2017) investigate children’s acquisition of universal quantification (every) and find that 4-year-olds stop saying “Yes” when they are asked whether (1) is true, given a picture where all but one cowboy is riding a horse (i.e. when there is an extra agent, a cowboy not riding a horse). However, 4-year-olds also start to make quantifier-spreading errors, where they say “No” to (1) when every cowboy is riding a horse but there is an extra object, a horse not being ridden by a cowboy.

(1) Every cowboy is riding a horse.

In this on-going experiment, we explore the interaction of negation and universal quantification in the grammar of 4-year-olds by asking them whether a sentence like (2) is true when they are given a picture where there is an extra agent (e.g. a picture with three giraffes each drinking a milkshake and a giraffe not drinking a milkshake) or an extra object (e.g. a picture with three giraffes each drinking a milkshake and a milkshake not being drunk by a giraffe).

(2) This is a picture where not every giraffe is drinking a milkshake.

The preliminary results replicate Aravind et al’s (2017) findings, suggesting that negation does not interact with universal quantification in a way that prevents 4-year-olds from making quantifier-spreading errors.

We propose that not and every are two independent, scope-taking elements in the grammar of 4-year-olds. To flesh out the syntactic and semantic properties of negation and universal quantification, we will address two theories of quantifier-spreading, Roeper et al (2005) and Denic and Chemla (2018), and discuss modifications need to be made to accommodate the preliminary results in our experiment.
