not at all. she incorporates work from all over, particularly psychology and anthropologists. I can't recite the variety, I left the book at work, but I'd say you've jumped to an unfair conclusion. Trained in sociology, I'd be the first one to whine if I thought she was ignoring insights from sociology.
Indeed, the biggest take away from this book is the unremitting emphasis on the social -- on social relations -- in the development of language and speech. Even in her chapters on research on the brain and on the following chapter on genetics, which I'm just now reading, what you are confronted with is the fact that you can't understand any of this without considering the effects of our social environment on the brain and genetics. (basically, from what I get on the genetics chapter, which I haven't finished, is that the idea that we have a blueprint for a genome has been tossed, even though it was the dominant view just five years ago. But again, book's at work, so I might need to revise that.)
