Perspective-taking in deriving implicatures: The listener's perspective is important too.

Theories of meaning propose that listeners understand a speaker's implicit meaning thanks to mutually assumed norms of conversation that take into account what the speaker has said, as well as contextual factors, including what the speaker knows. Emerging psycholinguistic research shows that listeners derive a particular kind of implicit meaning, quantity implicatures, when their speaker is knowledgeable about the situation but tend to not derive it otherwise. In this article we focus on if and how listeners use the knowledge that is available only to themselves, i.

Pragmatic, linguistic and cognitive factors in young children's development of quantity, relevance and word learning inferences.

To better understand the developmental trajectory of children's pragmatic development, studies that examine more than one type of implicature as well as associated linguistic and cognitive factors are required. We investigated three- to five-year-old English-speaking children's (N = 71) performance in ad hoc quantity, scalar quantity and relevance implicatures, as well as word learning by exclusion inferences, using a sentence-to-picture-matching story-based task. Children's pragmatic abilities improved with age, with word learning by exclusion acquired first, followed by relevance and ad hoc quantity implicatures, and finally scalar quantity implicatures.
