Language learning of children with typical development using a deductive metalinguistic procedure.

PURPOSE In the current study, the author aimed to determine whether 4- to 6-year-old typically developing children possess requisite problem-solving and language abilities to produce, generalize, and retain a novel verb inflection when taught using an explicit, deductive teaching procedure. METHOD Study participants included a cross-sectional sample of 4-, 5-, and 6-year-old children with typical cognitive and language development. The 66 participants were randomly assigned to either a deductive or inductive teaching condition in which they were taught a novel gender morphological inflection across 4 sessions. Learning was assessed on the basis of performance on learning, generalization, and maintenance probes. RESULTS Across all age groups, children were more likely to successfully use the novel gender form when taught using the deductive procedure than if taught using the inductive procedure (Φ range: .33-.73). Analyses within each age group revealed a robust effect for the 5-year-old children, with less consistent effects across the other age groups. CONCLUSIONS Study results suggest that 4- to 6-year-old children with typical language and cognitive abilities are able to make use of a deductive language teaching procedure when learning a novel gender inflection. Evidence also suggests that this effect is driven by expressive and receptive language ability.
