Acredolo and Goodwyn’s rebuttal against Nelson, White and Grewe’s Research!
Drs. Linda Acredolo and Susan Goodwyn wrote their response to the recent journal article written by L.H. Nelson, K.R. White, & J. Grewe. This journal article is titled as “Evidence for Website Claims about the Benefits of Teaching Sign Language to Infants and Toddlers with Normal Hearing” that was published in Infant and Child Development, Wiley Online Library, 2012.
I alerted Drs. Acredolo and Goodwyn about this article, and I made a video clip and added captions to make sure that Drs. Acredolo and Goodwyn understand to what I was signing. I posted my video clip to their Facebook page, Baby Sign Language, requesting for their response. Here’s my video clip from YouTube. It is captioned.

Today, Drs. Acredolo and Goodwyn alerted me that they posted their response paper to Nelson, White and Grewe’s paper on their website.
We feel strongly that Nelson, White, & Grewe did not review our NIH-funded research fairly. We stand by our conclusion that signing with hearing babies has a positive impact on verbal development. You can find a detailed, point by point response on our website.

Response to Research Critique
Whenever a particular idea or research finding becomes so popular that it is frequently cited by others, it almost inevitably becomes the target of “nay-sayers.” Our research on the positive effects of sign language on the development of hearing babies is no exception.
