Reception training effects on the production of modeled language constructions

Several previous studies have reported that first-grade-age children increase their usage of prepositional phrases when exposed to novel (inverted) prepositional constructions. The hypothesis was tested that such anomalous increases could be eliminated by discrimination training on the two prepositional forms. One group of first-grade subjects (age 72 months) was trained to respond differentially to sentences containing either familiar or novel prepositional constructions, while a control group received only exposure to the same sentences. As predicted, when later exposed to the modeling of novel constructions, children in the pretrained group did not increase their frequency of familiar prepositional phrases, while those in the control group did.
