Children’s Early Acquisition of the Passive: Evidence from Syntactic Priming

We report an experiment that examined 3and 4-year-old children’s representation of the passive structure. Early studies of typically-developing children’s acquisition of the passive suggest that this construction is acquired late and – or that its acquisition is semantically constrained: children comprehend actives much earlier than passives and comprehend actional verb passives earlier than non-actional verb passives (Maratsos, Fox, Becker & Chalkley, 1985). Conversely, some production studies have shown the passive is acquired earlier than thought: 3-4 year old children produce passives following training (Brooks & Tomasello, 1999) and priming (Huttenlocher, Vasilyeva & Shimpi, 2004), however, such studies have not examined whether the passive is constrained to actional verbs early on. We report a syntactic priming study that manipulated Prime Structure (active vs. passive) and Verb Type (actional vs. non-actional). We found a strong and reliable effect of Prime Structure for children (27%) and adult controls (19%). There was, however, no effect of Verb Type (Fs < 2). Participants were more likely to produce passive targets following passive primes than active primes, irrespective of the verb. We conclude that children do acquire an abstract syntactic representation for the passive early on (by 3-4 years) that is not constrained by verb type.
