Sensory and Social Development in Infants and Toddlers (SASI) find out more

SASI is a longitudinal study which aims to understand individual differences in social and sensory development in typically developing and high-risk infants and toddlers. This study examines these domains through behavioral and physiological measures. We will be looking for families with an infant or toddler between the ages of 6 and 16 months to participate. We will be recruiting both a general community sample of infants as well as infants who have an older sibling with autism spectrum disorder (ASD) and may be at higher familial risk. Study participation includes a brief survey and, depending on survey outcomes, 3 assessment time points over 3 months. Your family will be compensated for your time (up to $150), and parking is provided.

Sensory Experiences Project (SEP) find out more

The SEP was a 10-year longitudinal study that has concluded enrollment and is in the data analysis phase. The purpose of this project was to explain the development, functional impact, and pathogenesis of unusual sensory experiences in children with ASD, developmental delay and/or typical development with implications for early identification and intervention. The SEP also examined sensory subtypes of children with ASD.

The SEP included a series of six studies:

Southern California Child Development Survey (SoCal CDS) find out more

SoCal CDS is a survey study examining children’s development from 6 to 16 months of age in domains such as social communication and sensory regulation. We are recruiting families from communities within the greater Los Angeles area to collect normative data on a diverse population. Participants will complete a 15-20 minute survey including the “First Years Inventory” (FYI), a questionnaire which asks parents about how their child responds to people, objects, and events. The survey also includes questions about developmental history and any potential concerns. Data obtained from birth records will also be used for analyses with survey outcomes to describe and correlate demographic and perinatal factors such as Apgar scores.
