This book is a wonderful addition to anyone's linguistic library. Golinkoff and Hirsh-Pasek have done it again! I look forward to thier new popular press book about how babies talk.

"THE ORIGINS OF GRAMMAR presents a synthesis of work done by the authors, using ... the intermodal preferential looking paradigm, which can be used to assess lexical and syntactic knowledge in children as young as thirteen months of age. In addition to drawing together their ground-breaking empirical work, the authors use these results to describe a theory of language learning that emphasizes the role of multiple cues and forces in development. They show how infants shift their reliance on different aspects of linguistic input, moving from a bias to attend to prosodic information to a reliance on semantic information, and finally to a reliance on the syntax itself."

Este es un excelente libro que describe el desarrollo del lenguaje desde el vientre materno hasta los 4 años. Es uno de los libros más serios que existen en lengua castellana y resume en forma sencilla, los descubrimientos más recientes en los laboratorios de desarrollo de lenguaje. El libro representa un esfuerzo no solo en traducción, sino en adaptación a la adquisición del castellano. Es un libro que todos los padres de niños pequeños deben leer, así como los terapeutas de lenguaje y profesores de preescolar.

My son is 16 months and this book was helpful in pointing out to me that he was saying things, I just was looking for better formed words and not listening very well (chalk it up to first time mom)!

However, the book states that the average age a baby talks is 12 months, but can go to 24 months. There was a study mentioned in their book that stated the average first word in the study was produced at 13.5 months.

I do not think this book is helpful for parents trying to find encouragement and answers as to why their child isn't talking. Most of the examples they give of first word talkers at 12 and 13 months. There is mention of a 17 month 1st word talker, but their reason was because he had ear infections.

I would have liked to read more examples of later talkers without any "ear infections" or disabilites being the case.

I found this book extraordinarily helpful in understanding and tracking my daugher's learning. I gained three valuable insights from this book: (1) a clearer understanding of how language acquisition occurs (2) specific examples of how I can assist my child with the language acquisition process (3) a valuable insight to how much my daughter can understand prior to her ability to communicate it.

This book brought additional enjoyment because after reading this book, I immediately noticed additional examples of my daughter's progression in language learning that I'd previously overlooked.

Additionally, the book contains a balanced mixture of research and specific examples. This combination makes it both credible and readable. I actually found it hard to put down, which is very impressive for a research based book!

I'd also highly recommend Baby Signs by Linda Acredolo

This book offers a parent some insight into the processes involved for a baby learning to speak. I have found myself rereading each age-related section as my son ages. More than anything, I think this book helped me to relax about my son's learning to talk; speech development is occuring even though it might not be verbalized at the moment. The references to the various research studies offered me some ideas about methods of communicating with my son without the aid of his speech. His glances, his reactions, all are methods of communicating with me, as long as I'm receptive enough to pay attention!

This is an amazing book by means of child linguistics. I am a college professor at Florida University where I teach child phsycology. Not only does Rescorlo look beneath the surface of development from One to three, she goes beyond to inform the reader of other linguistics. I want to see Rescorlo write a popular press book in the near future. I recomend this book to anyone interested in the milestone of language development
