Language and Play at One Year: A Comparison of Toddlers and Mothers in the United States and Japan

Abstract
The present study compared American and Japanese toddlers and their mothers on dimensions of language and play when the toddlers were 13 months of age. In both cultures and in both domains, individual variation in toddlers was associated with individual variation in mothers. In general, the frequency and variance of language and play activities were similar in the two groups. However, two notable cultural differences emerged. American toddlers were more advanced in both their productive and receptive vocabularies, and this cultural difference was matched by the tendency for American mothers to label and desciibe properties, objects, and events in the environment more frequently. In contrast, Japanese toddlers were more advanced on symbolic play, and their advanced play was matched by more advanced play in Japanese mothers, particularly for "other-directed" acts of pretence. These findings suggest that during this early period of symbolic development, as expressed through language and play, American and Japanese dyads emphasise different modes of representation and do so in ways that accord with traditional cultural concerns.
