An ongoing debate in the literature on language acquisition is whether preschool children process reference in an egocentric way or whether they spontaneously and by-default take their partner's perspective into account. The reported study implements a computerized referential task with a controlled trial presentation and simple verbal instructions. Contrary to the predictions of the partner-specific view, entrained referential precedents give rise to faster processing for 3- and 5-year-old children, independently of whether the conversational partner is the same as in the lexical entrainment phase or not. Additionally, both age groups display a processing preference for the interaction with the same partner, be it for new or previously used referential descriptions. These results suggest that preschool children may adapt to their conversational partner; however, partner-specificity is encoded as low-level auditory-phonological priming rather than through inferences about a partner's perspective.
