International Infant Sign Researchers

International Infant Sign Researchers (IISR) is a group of scholars from around the world who are each studying the use of signs – or symbolic gestures – with and by infants. ┬áThe purpose of this group is to facilitate discussion about our research and potential for collaboration among researchers.

The IISR is currently composed of more than 30 members from 13 different countries represented on the map below, including: Canada, Chile, England, France, Germany, Israel, Italy, Macau (China), the Netherlands, Scotland, South Korea, Spain, and the United States.

Together, we have collaborated to present our work at international conferences, and designed and carried out cr0ss-cultural studies on infant signs, including the Cross-Cultural Experiences of Infant Sign (CCEIS) study. Data from the CCEIS Study come from families using infant signs all around the world:
