Structural priming as implicit learning: Cumulative priming effects and individual differences

We explored the claim that structural priming is a case of implicit learning within the language production system. The experiment began with a baseline phase, in which we assessed participants' rates of production for double object and prepositional object constructions. Then participants were biased toward the production of either the double object or prepositional object construction. Finally, we again assessed participants' rates of production for the target constructions. Consistent with claims that structural priming is a case of implicit learning, we found that biasing participants toward the prepositional object construction produced stronger cumulative priming effects than did biasing participants toward the double object construction. We also found that individual differences in implicit learning were marginally correlated with overall rates of production for the double object construction. Participants who scored better on the learning task tended to produce fewer double object constructions.
