Children can communicate through gestures (like pick-me-up or pointing) even before they begin to speak. Some gestures likely develop through social learning (like waving hello). Researchers have argued that other early gestures, like the pick-me-up gesture, cannot be learned through social learning (since adults do not gesture to be picked up). They have therefore proposed that these gestures are learned through ontogenetic ritualization, a kind of learning that critically involves role and dyad specificity. Ontogenetic ritualization is thought to differ from operant conditioning. In this presentation, on the basis of videotaped interactions between parents and children between six and twelve months of age, I argue that these early communicative gestures are likely learned through operant conditioning. I also discuss the possible developmental origins of pointing, ranging from operant conditioning to species-typical behavior. It is important to entertain the possibility that simple and well-established learning mechanisms account for children’s early gestures.

Anyone interested in the early communication of typically developing infants and toddlers as well as practitioners interested in designing interventions with clinical communication-disordered populations.
