= 48) read instructions to an experimenter (adult-directed) and then to their own 2- to 3-year-old children (child-directed). In Experiment 1, speakers produced sentences containing high-frequency target nouns, and in Experiment 2, they produced sentences containing low-frequency target nouns. In both CDS and ADS in both experiments, speakers reduced repeated mentions of target nouns across successive utterances. However, speakers reduced less in CDS than in ADS, and low-frequency nouns in CDS were overall longer than low-frequency nouns in ADS. Together, the results suggest that repetition reduction may be beyond speaker control, but that speakers still engage in audience design when producing words for relatively inexperienced listeners. We conclude that language production involves nested audience-driven and speaker-driven processes. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
