We are currently collecting data to increase knowledge of the development of visual attention in infants with or without older siblings with autism spectrum (ASD) or a related disorder.

Phase 1
We are collecting data from infants who are between 8 and 12 months old and either have:

1. An older, full biological sibling with ASD, or
2. Do not have any first-, second- or third-degree relatives with an ASD diagnosis. First-degree relatives are parents and siblings. Second-degree relatives include an individual's grandparents, uncles, aunts, nephews, nieces, and half-siblings. Third-degree relatives include an individual's great-grandparents, great uncles/aunts, and first cousins.

Initial participation involves collecting fecal samples from the contents of the infant's diaper, storing them in special test tubes, and allowing us to pick them up within 48 hours.

Phase 2
Participation (8 months after phase 1) involves infants coming to the lab to perform visual tasks (to measure novelty preference ). We collect fecal (stool) samples and the parents complete a questionnaire. We use the fecal samples to analyze gut microbiota, which can influence the brain and behavior.

Phase 3
Participation (8 months after phase 2) involves behavioral testing, if applicable to the family. Fecal samples are collected for the third time.

Additionally, small hair samples will be collected from parents during each of the three phases, to measure stress using hair cortisol analysis.
