Gaze direction detection in autism spectrum disorder.
Clients with autism need larger gaze shifts to notice where you look—make your cues bigger and task-driven.
01Research in Context
What this study did
Forgeot d'Arc et al. (2017) asked adults and teens to judge where a face was looking.
Some had autism, some did not.
The team slowly widened the eye angle until each person could tell left from straight.
What they found
People with autism needed a bigger angle than controls before they could say "left."
In plain words, they were less sharp at spotting gaze shifts.
This gap held across the whole age range tested.
How this fits with other research
Zhao et al. (2017) saw the same weakness when the scene was busy, showing the problem survives clutter.
Wallace et al. (2008) once thought kids outgrow this, but Baudouin’s mixed-age sample says the gap stays.
Laposa et al. (2017) looked at low-functioning toddlers and found no heart-rate jump to direct gaze—seemingly opposite, yet both studies point to early avoidance that may feed the later acuity loss.
Wang et al. (2023) flipped the script: preschoolers with autism looked more at eyes when the task asked them to act, hinting the deficit can be nudged, not fixed.
Why it matters
When you teach joint attention, give bigger gaze cues—think 10° not 2°—and watch for a response.
Add active steps like naming the eye color to pull attention forward, then fade the angle as skills grow.

03Original abstract
Detecting where our partners direct their gaze is an important aspect of social interaction. An atypical gaze processing has been reported in autism. However, it remains controversial whether children and adults with autism spectrum disorder interpret indirect gaze direction with typical accuracy. This study investigated whether the detection of gaze direction toward an object is less accurate in autism spectrum disorder. Individuals with autism spectrum disorder (n = 33) and intelligence quotients-matched and age-matched controls (n = 38) were asked to watch a series of synthetic faces looking at objects, and decide which of two objects was looked at. The angle formed by the two possible targets and the face varied following an adaptive procedure, in order to determine individual thresholds. We found that gaze direction detection was less accurate in autism spectrum disorder than in control participants. Our results suggest that the precision of gaze following may be one of the altered processes underlying social interaction difficulties in autism spectrum disorder.
