Dr. Linda Acredolo and Dr. Susan Goodwyn, the authors of the bestselling book, BABY SIGNS: How to Talk with Your Baby Before Your Baby Can Talk, have conducted over 20 years of research studies, including a long-term study funded by the National Institutes of Health. The findings from their research validate the benefits of the Baby Signs Program.

RESEARCH HIGHLIGHTS

PARTICIPANTS

More than 140 families joined the study beginning when their babies were 11 months old. Each family was randomly assigned to a Baby Signing or non-Baby Signing group. The groups were equivalent at the beginning of the study in terms of the following characteristics: sex, birth order of the children, their tendency to vocalize or verbalize words, and the parents' education or income levels.

ASSESSMENTS

The children assessed using standardized language measures at 11, 15, 19, 24, 30, and 36 months old. In addition, as many children as could be relocated at age 8 were assessed using the WISC-III IQ test, the most commonly used measure of children's intelligence.

RESULTS

Baby Signers at 24 months were on average talking more like 27- or 28-month-olds, representing more than a three-month advantage over the non-Baby Signers. In addition, the Baby Signers were putting together significantly longer sentences.

At 36 months, Baby Signers on average were talking like 47-month-olds, putting them almost a full year ahead of their average age-mates.

Eight-year-olds who had been Baby Signers scored an average of 12 points higher in IQ than their non-Baby Signing peers.

CONCLUSION

Using Baby Signs helps children develop both language and cognitive skills.
