First published in 1977, this book draws together various contributions on the area of speech used by parents with their children. Numerous perspectives on the topic include the comparison of baby talk with other simplified registers by linguists, the analysis of cross-cultural differences in mother and child interaction by anthropologists, and the relation of language development to differences in styles of childcare and the child's social environment in general by psychologists. The text had its origins in a conference sponsored by the Sociolinguistics Committee of the Social Science Research Council. It will be of value to anyone with an interest in language acquisition and development.
