Parents spontaneously scaffold the formation of conversational pacts with their children

Adults readily coordinate on temporary pacts about how to refer to things in conversation. Young children are also capable of forming pacts with peers given appropriate experimenter intervention. Here, we investigate whether parents may spontaneously provide a similar kind of scaffolding with U.S. children in a director-matcher task (N = 201, 49% female; ages 4, 6, 8). In Experiment 1, we show that parents initiate more clarification exchanges with younger children who, in turn, are more likely to adopt labels introduced by the parent. We then examine whether the benefit of such scaffolding acts primarily through childrens' difficulties with comprehension (Experiment 2) or production (Experiment 3). Our findings suggest that parents primarily scaffold pacts by easing children's production difficulties, modeling cooperative communication.
