People use language to communicate their perceptions and conceptions of the world, and underlying this communication is the linguistic system that interacts with the human perceptual and conceptual machinery. This is supported by research on sentence comprehension among adults. This chapter examines theories of sentence processing in children and adults. It comments on a study John Trueswell et al. in which they demonstrated that five-year-old children appeared to be unable to use contextual cues to resolve ambiguity in sentences such as (...) “Put the frog on the napkin into the box.” Trueswell et al. explained this finding by arguing that children have limited working memory capacity that prevents them from using information from the context to disambiguate linguistic input. The chapter first discusses real-time sentence processing in adults before presenting a developmental account of sentence comprehension. It then considers the so-called Kindergarten-path Effect along with referential scenes, definite reference, and restrictive modifiers. It also looks at the effects of discourse and pragmatics on parsing by children and concludes with a discussion of the development of attention in children. (shrink)

Currently, production and comprehension are regarded as quite distinct in accounts of language processing. In rejecting this dichotomy, we instead assert that producing and understanding are interwoven, and that this interweaving is what enables people to predict themselves and each other. We start by noting that production and comprehension are forms of action and action perception. We then consider the evidence for interweaving in action, action perception, and joint action, and explain such evidence in terms of prediction. Specifically, we assume (...) that actors construct forward models of their actions before they execute those actions, and that perceivers of others' actions covertly imitate those actions, then construct forward models of those actions. We use these accounts of action, action perception, and joint action to develop accounts of production, comprehension, and interactive language. Importantly, they incorporate well-defined levels of linguistic representation. We show how speakers and comprehenders use covert imitation and forward modeling to make predictions at these levels of representation, how they interweave production and comprehension processes, and how they use these predictions to monitor the upcoming utterances. We show how these accounts explain a range of behavioral and neuroscientific data on language processing and discuss some of the implications of our proposal. (shrink)
