Preference for Geometric Patterns Identified as a Possible Early Sign of Autism

Participants included 110 children, ages 14-42 months. Of the participants, 37 had ASD, 22 had developmental delay, and 51 had typical development. The participants’ preference for geometric patterns versus social images was measured using eye tracking technology. The participants were shown a minute long video, in which the screen was divided in two halves. One half of the screen displayed social images of children dancing and doing yoga while the other half displayed geometric patterns. Eye tracking technology measured how long each participant looked at each half of the screen.
