Infant pointing is predictive of later language development, but little is known about factors enhancing the development of pointing. The current study investigated two possible social learning mechanisms in the development of pointing. Given that infants observe their caregivers' pointing gestures from early on, one possibility is learning via…

Parity is one source of automatic reinforcement that increases the probability of verbal behavior that conforms to models provided by the verbal community. Parity as a conditioned reinforcer could explain the acquisition of grammar in the absence of direct, explicit reinforcement. This possibility has been explored in previous research on…

Communication instructors have long insisted on the importance of audience adaptation. But they have said less about (a) the dimensions along which adaptation might proceed or (b) how a student might learn the art of adapting. In this article, I contribute toward addressing these two deficiencies. I suggest a dimension for adaptation - the value…

From early in life, children learn to perform actions on the objects in their environments. Although children learn from observing others' actions, actively engaging with the material to be learned can be important for learning. This study tested whether instruction that included opportunities for children to be active supported toddlers' action…

In Experiment I, I tested the effects of a vicarious reinforcement procedure on the establishment of conditioned reinforcement for observing books (CR+ for observing books) using a pre- and post-intervention embedded with a multiple probe design across two dyads. All four participants could textually respond to kindergarten or first-grade level…
