Abstract	This study examined how toddler looking to a discourse referent is mediated by the information status of the referent and the pitch contour of the referring expression. Eighteen-month-olds saw a short discourse of three sets of images with the proportion of looking time to a target analyzed during the final image. At test, the information status of the referent was either "new" or "given" and the referring expression was presented with one of three pitch contours ("flat f0," "monotonal ([approximately]H"), or "bitonal" ("[approximately]L+H")). In Experiment 1, toddlers looked reliably longer to a target referent when it was either "new" to the discourse or carried a non-flat pitch contour. In Experiment 2, the referring expression was removed to observe effects of information status alone on looking to a target referent. Toddlers looked significantly longer to a target when it was "new" versus "given." More fine-grained time course analyses of eye movements revealed differences in the speed and duration of fixation to a target. Overall, the experiments show that discourse reference in toddlers is mediated by the presence of newness and pitch contours, even in the case of "given" information. (As Provided).
