Help Michigan State University with Child Development Research

Two Little Hands Productions is inviting you to participate in an international research project from Michigan State University. Please take a few minutes to read this letter from the research team below to see if you qualify to take the survey.

Dear Parents,

We are researchers in Child Development from several universities around the world. We are conducting a cross-cultural study on parents’ experiences using infant signs – a form of simple sign language used with normally hearing children before they can talk. From this study, we will learn valuable information about cross-cultural similarities and differences in parenting and child development. It will take about 15 to 30 minutes for you to complete the survey. After completing it, you will be entered into a drawing where you can win a $50 gift card to your choice of online stores (you will have at least a 1 in 100 chance of winning).

We are looking for parents who are at least 18 years old, who have a child who is 8 years or younger, and who use signs or are considering using signs with their child. If you meet these criteria and would like to take the online survey, please click the link here:

Thank you very much for your help!
