Brief description of study

What is the purpose of this study?
The study will use a non-invasive remote eye-tracking system (Eyelink Portable Duo) to acquire a short series (less than 15 mins) of eye-tracking measures (e.g., look time, pupil diameter), which may be associated with autism in young children ages 12-48 months. We will recruit children from Riley Hospital for Children at Indiana University Health clinics to determine whether these measures may help determine autism risk.
 
THIS STUDY IS ENROLLING BY INVITATION ONLY - Children will be recruited from Riley Hospital for Children at Indiana University Health clinics. The research coordinator will review in the EMR upcoming patients scheduled in these clinics who meet study eligibility requirements. The coordinator will contact children's caregivers directly by phone to provide information about the research study and determine interest. All study procedures will occur in Riley Hospital for Children at Indiana University Health clinics (e.g., Pediatric Care Center clinics).

Detailed description of study

What will happen during the study?
  • The study will use a non-invasive remote eye-tracking system (Eyelink Portable Duo) to acquire a short series (less than 15 minutes) of eye-tracking measures associated with autism risk in young children.
  • Eye-tracking data will be collected using a commercially-available remote eye-tracking system (Eyelink Portable Duo), which is placed in front and below the stimulus presentation monitor.
  • Eye movements and pupil diameter will be collected while participants view a series of developmentally appropriate pictures and movies (i.e., cartoons).
  • The modular system is completely non-invasive with no hardware on or touching participants (only a smaller sticker is placed on their forehead to the location of the head).
  • The eye-tracker consists of two cameras; one that monitors eye movements and a second scene camera that monitors head movements, which permits eye tracking to take place without any equipment touching the child.
  • Children will be asked to sit in highchair or on their caregiver’s lap and will face a computer monitor.
  • After the sticker is applied to the child's forehead and brief eye-movement calibration completed, next visual stimuli (i.e., pictures and videos) will be presented on a laptop computer monitor that is placed at approximately 60-80cm from the child.
  • Brightness will be at a comfortable viewing level.
  • The eye tracking portion of the visit will last approximately 15 minutes or until the child is no longer able to attend to pictures/videos.
