Babies Learn Early Who They Can Trust A study indicates that babies may choose not to learn from someone they don't trust. A group of 60 babies, aged 13 to 16 months, were randomly divided into two groups. Each baby watched an adult express great excitement while looking into a box. The babies were then shown the box and it either had a toy in it (the adult could be trusted) or it was empty (the adult was not reliable.) The same adult then turned on a push-on light with her forehead, and the number of babies who imitated the adult's behavior by doing the same thing was counted. The results are in Table 1. Test at a 5 % level to see if there is evidence that babies are more likely to imitate those they consider reliable.
