Early Language Development in Infants and Toddlers from Non-English Speaking Homes - SPANISH/ENGLISH VERSION


IRB Number: NCR202656


We are learning about how young English/Korean/Spanish-speaking children in the United States use language. We want to know how the family’s language use in the home changes the children’s language development. The study has three parts: an online survey (link below, 20 minutes); a phone or video interview (40 minutes); and an optional video recording of your child repeating 10-20 common words (5 minutes). All study materials are available in English, Spanish, and Korean.

To qualify, you must be the parent or guardian of a child 12-24 months old and speak Spanish in your home at least some of the time.
