Infant-parent play with toys is an early form of social communication, and the toy features (i.e., affordances), as well as the child's language competence, contribute to the developmental level of the play and the types of play actions that occur. This research, conducted in cooperation with a toy manufacturer, investigated how the affordances of a technology-enhanced toy were used by 26 infant-parent pairs during six clinical sessions of play with the toy. The types of play, the features of the toy that elicited play, the humor elicited by the toy, and the communicative interactions of the parent and child were observed. Results indicated that certain affordances of the toy were used in exploration, practice play, and social games and were related to episodes of child laughter. The communicative interactions of the parents and the language patterns used in the sessions grew in complexity as the children's language facility increased. The affordances of the toy played a role in a variety of parent-child interactions and joint attention experiences. (Contains 3 tables and 2 figures.)
