This project began in the Fall of 2002. Since that time, we have tested approximately 300 infants with funding from grants provided by the UC-Davis M.I.N.D. Institute and the National Alliance for Autism Research (NAAR). In 2004, an additional grant from the M.I.N.D. Institute made it possible to follow-up our participants with behavioral assessments through 36-months of age. As of February 2006, we have been incorporated into the multi-site project known as "High Risk Baby Siblings Autism Research," which is funded by NAAR/Autism Speaks and includes over 15 research groups across the USA and in Canada. In July 2006 we received additional funding from NAAR/Autism Speaks that will cover the expenses of our project until 2008. We hope to secure additional funding to facilitate the follow-up of participants to five years (60-months) of age.
