BOX 4.5 Which Toy? Consider the efforts to reach an understanding between an adult and a 14-month-old about which toy the infant wants to play with. The adult is looking for a toy in the toy box. When he touches the tower of rings, the baby exclaims, "Aa!" The adult responds, "Aa?" picking up the tower. The infant continues looking at the toy box and ignores the tower, so the adult shows the baby the tower and again asks "Aa?" The baby points at something in the toy box grunting, "Aa . . . aa . . . " The adult reaches toward the toy box again, and the infant exclaims, "Tue!" The adult exclaimed "Aa!" as he picks up the peekaboo cloth and shows it to the infant. But the infant ignores the cloth and points again at something in the toy box, then, impatiently, waves his arm. The adult responds, "Aa?" But the baby points down to the side of the toy box. They repeat the cycle with another toy, and the baby waves his arm impatiently. The adult says "You show me!" and lifts the baby to his lap from the high chair. The adult then picks up the jack-in-the-box, asking, "This?"--the baby opens his hand toward the toy, and they began to play (Rogoff et al., 1984:42-43).
