ABSTRACT
A recent study (Bandura & Harris, 1967) examined the effects of several social-learning variables on children's pro duction of two syntactic constructions. The results demonstrated that those children exposed to a combination of (a) an adult model's production of sentences with and without the relevant construction, (b) reward for sentences containing the relevant construction, and (c) attention-focusing instructions showed a greater increment in the production of these constructions (pas sive or prepositional phrases) in their own sentences than did a control group.
