Syntactic priming during language comprehension in three- and four-year-old children

We report two sets of experiments that demonstrate syntactic priming from comprehension to comprehension in young children. Children acted out double-object and prepositional-object dative sentences while we monitored their eye movements. We measured whether hearing one type of dative as a prime influenced children’s online interpretation of subsequent dative utterances. In target sentences, the onset of the direct object noun was consistent with both an animate recipient and an inanimate theme, creating a temporary ambiguity in the argument structure of the verb (double-object e.g., Show the hor se the book; prepositional-object e.g., Show the hor n to the dog). The first set of experiments demonstrated priming in four-year-old children (M = 4.1), both when the same verb was used in prime and target sentences (Experiment 1a) and when different verbs were used (Experiment 1b). The second set found parallel priming in three-year-old children (M = 3.1). These results indicate that young children employ abstract structural representations during online sentence comprehension.
