Input effects on the acquisition of a novel phrasal construction in 5 year olds

The present experiments demonstrate that children as young as five years old (M = 5:2) generalize beyond their input on the basis of minimal exposure to a novel argument structure construction. The novel construction that was used involved a non-English phrasal pattern: VN1N2, paired with a novel abstract meaning: N2 approaches N1. At the same time, we find that children are keenly sensitive to the input: they show knowledge of the construction after a single day of exposure but this grows stronger after 3 days; also, children generalize more readily to new verbs when the input contains more than one verb.

► Novel construction learning in 5 year olds.
► Children learn and generalize from minimal exposure.
► Knowledge of the construction becomes more precise and robust with increased exposure.
► Generalization to new verbs is affected by type frequency.
