Use of Eye Tracking to Aid in Autism Risk Detection

Conditions

Eyelink Portable Duo — DIAGNOSTIC_TEST
Eye-tracking data will be collected using a commercially-available remote eye-tracking system (Eyelink Portable Duo). Eye movements and pupil diameter will be collected while participants view a series of developmentally appropriate pictures and movies. 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 a 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. 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.

The study will use a non-invasive remote eye-tracking system (Eyelink Portable Duo) to acquire a short series of eye-tracking measures.

Experimental: Children Undergoing Developmental Evaluation
Children undergoing a standard of care developmental evaluation will be enrolled into the study. After the completion of the developmental evaluation, research participation includes a one-time eye-tracking activity in which the child will view a series of different pictures and movies while their eye movements are tracked and recorded.
