Two eye-tracking experiments examine whether adults and 4 and 5 year old children use the presence or absence of accenting to guide their interpretation of noun phrases (e.g., the bacon) with respect to the discourse context. Unaccented nouns tend to refer to contextually accessible referents, while accented variants tend to be used for less accessible entities. Experiment 1 confirms that accenting is informative for adults, who show a bias toward previously-mentioned objects beginning 300 msec after the onset of unaccented nouns and pronouns. But contrary to findings in the literature, accented words produced no observable bias. In Experiment 2, 4 and 5 year olds were also biased toward previously-mentioned objects with unaccented nouns and pronouns. This builds on findings of limits on children's on-line reference comprehension (Arnold, Brown-Schmidt, & Trueswell, in press), showing that children's interpretation of unaccented nouns and pronouns is constrained in contexts with one single highly accessible object.Learning to understand language involves more than just words and grammatical rules. Children must learn to interpret words and sentences by connecting them with the preceding discourse and the larger context -and to do so very rapidly, as each word and sentence comes at them. This study investigates young children's ability to generate on-line hypotheses about the referent of expressions like the bagel, with a focus on understanding whether children utilize the presence or absence of an accent to guide these hypotheses. Unaccented words tend to refer to information that is highly accessible in the discourse, while accented words tend to refer to less accessible information (e.g., Venditti & Hirschberg, 2003). Research has shown that adults are highly sensitive to this information, and use it rapidly to guide their interpretation of the nominal referring expression (Dahan, Tanenhaus, & Chambers, 2002). It is not known how accenting is used by children during reference comprehension. Furthermore, what is known about reference comprehension in children presents conflicting information about their ability to integrate linguistic referring expressions with the discourse context.
Reference comprehension and interpretation of accents: AdultsWhen adults interpret spoken referential expressions, they rapidly utilize detailed information about the linguistic expression to identify the most likely referent, This process is embedded in discourse processing mechanisms whereby adults maintain a mental representation of the entities in the current discourse situation (e.g., van Dijk & Kintsch, 1983;Kintsch, 1988;Johnson-Laird, 1983;Bransford, Barclay & Franks, 1972, Bower & Morrow, 1990; Sanford Address correspondence to: Jennifer Arnold, CB #3270 Davie Hall, Rm. 337B, Chapel Hill, NC 27599-3270, 919-843-5737, fax: 919-962-2537, jarnold@email.unc.edu.
