Predictive gaze during observation of irrational actions in adults with autism spectrum conditions.
Autistic adults miss action details because they look less, not because they can't predict goals—so prompt attention to hands and goals during social skills training.
01Research in Context
What this study did
Austin et al. (2015) watched where autistic and non-autistic adults looked while they viewed short clips of everyday actions.
The clips showed odd moves, like pouring juice into a cup that was upside-down. A camera tracked each viewer’s eyes 60 times per second.
The team asked: do autistic adults look less at the hand and goal, and are their eye jumps to the next goal slower?
What they found
Autistic adults looked at the hand and cup less often, but when they did look, their eyes jumped ahead just as fast as controls.
The missing piece is not prediction skill; it is getting the eyes to the right spot in the first place.
How this fits with other research
Gowen et al. (2022) seem to disagree: they found autistic adults were worse at guessing when an action would re-start after the screen went blank. The two studies differ in one key way. E et al. gave full sight of the action, while Emma et al. hid part of it. Full sight keeps timing intact; hidden sight exposes tiny timing gaps.
Hou et al. (2024) extend the story downward. Autistic children’s eyes wander more, and the more they wander, the worse they are at guessing what will happen next. Taken together, the picture is: unstable looking starts in childhood, turns into reduced looking in adulthood, and only shows timing problems when the view is blocked.
Benson et al. (2016) and Caruana et al. (2018) add similar adult data. Autistic adults need more looks to spot social oddities and start joint-attention trials more slowly, matching the theme of intact skill once attention is secured, but fragile attention at the start.
Why it matters
If the client is not looking, they are not learning. Use brief verbal or point cues to draw gaze to hands and goals before you model a social skill. Keep the action visible; avoid covering objects or turning away while you demonstrate. These tiny attention nudges can lift prediction without extra drills on timing.

03Original abstract
Understanding irrational actions may require the observer to make mental state inferences about why an action was performed. Individuals with autism spectrum conditions (ASC) have well documented difficulties with mentalizing; however, the degree to which rationality understanding is impaired in autism is not yet clear. The present study uses eye-tracking to measure online understanding of action rationality in individuals with ASC. Twenty adults with ASC and 20 typically developing controls, matched for age and IQ watched movies of rational and irrational actions while their eye movements were recorded. Measures of looking time, scan path and saccade latency were calculated. Results from looking time and scan path analyses demonstrate that participants with ASC have reduced visual attention to salient action features such as the action goal and the hand performing the action, regardless of action rationality. However, when participants with ASC do attend to these features, they are able to make anticipatory goal saccades as quickly as typically developing controls. Taken together these results indicate that individuals with autism have reduced attention to observed actions, but when attention is maintained, goal prediction is typical. We conclude that the basic mechanisms of action understanding are intact in individuals with ASC although there may be impairment in the top-down, social modulation of eye movements.
