Eye direction, not movement direction, predicts attention shifts in those with autism spectrum disorders.
Adults with autism automatically shift attention to eye direction once motion noise is removed.
01Research in Context
What this study did
The team asked adults with and without autism to watch a screen. A face appeared in the center. The eyes moved, then stopped. A target dot flashed on the left or right. Participants pressed a key when they saw the dot.
The trick: the moving eyes always turned away from the final target side. Only the last frozen eye position pointed to the dot. This let the researchers test if attention follows motion or final gaze direction.
What they found
Both groups shifted attention to the final eye direction, not the motion path. The autism group showed the same quick, automatic orienting as the neurotypical group.
When motion cues were removed, reflexive gaze following looked completely intact in adults with autism.
How this fits with other research
Fletcher-Watson et al. (2008) ran a change-blindness task and got the same positive result: young autistic adults noticed gaze changes as fast as peers. Together, the two 2008 papers say basic gaze-cueing is intact in autism once you strip away extra demands.
Rombough et al. (2013) extends the story to children. They also found intact automatic cueing, but added a twist: when kids had to choose eyes over arrows, autistic children struggled. Reflexive orienting works; choosing to use eyes is harder.
Freeth et al. (2019) seems to disagree at first glance. They saw less face looking in autistic adults during live chat. The difference is context. D et al. used brief, isolated cues. Megan used real eye contact, which can feel aversive. Intact reflexes in the lab do not guarantee comfortable reciprocal gaze in conversation.
Why it matters
If a client does not follow your point or gaze, the bottleneck is probably not the basic cue-detection circuit. You can build on that intact skill. Instead, teach when and why to use gaze, and reduce social anxiety that may block natural looking. Start with brief, clear eye cues in low-pressure settings, then fade in more interactive contexts.

03Original abstract
Experiments suggesting that a change in eye gaze creates a reflexive attention shift tend to confound motion direction and terminal eye direction. However, motion and the onset of motion are known to capture attention. Current thinking about social cognition in autism suggests that there might be a deficit in responding to social (eye gaze) cues but not non-social (motion direction) cues, making the current study theoretically critical. We report an experiment in which motion direction and eye direction are decoupled in order to determine which predicts attention shifts in adults with and without autism. In the Eye Movement condition the eyes moved towards or away from a target. In the Face Movement condition the face image shifted while pupils remained stationary on the screen, resulting in terminal eye gaze and motion being in opposite directions. Reflexive attention shifts in both groups followed terminal eye direction, rather than direction of movement.
