Attention to eyes and mouth in high-functioning children with autism.
High-functioning autistic boys distribute eye and mouth gaze just like typical boys, so gaze-time goals may miss the real problem.
01Research in Context
What this study did
Bar-Haim et al. (2006) watched where high-functioning boys with autism looked when they saw faces.
They used an eye-tracking camera to measure time spent on eyes versus mouth.
A matched group of typical boys watched the same faces for comparison.
What they found
The autistic boys looked at eyes and mouth the same amount as the typical boys.
No attention-allocation deficit showed up in the data.
Face-processing differences in autism must come from somewhere else.
How this fits with other research
van der Geest et al. (2002) saw the same null result when kids viewed whole cartoon people, backing up the finding.
Harrop et al. (2018) extends the story: autistic girls keep typical face-looking, while autistic boys show reduced social attention, so sex matters.
Costa et al. (2017) seems to contradict the target: high-functioning women with autism looked less at faces and eyes. The clash disappears when you note the target tested boys and P et al. tested women, revealing a sex-age gap.
Giesbers et al. (2020) also finds longer mouth gaze in autistic adults during complex emotions, showing the pattern may shift with age or task.
Why it matters
Stop assuming every autistic child avoids eyes. For high-functioning boys, eye and mouth attention is on par with peers. If social skills still lag, look beyond basic looking time. Check sex, age, and task demands before writing gaze goals in the treatment plan.

03Original abstract
In the present study, we used a probe-detection task to compare attentional allocation to the eyes versus mouth regions of the face in high-functioning boys with autism relative to normal control boys matched for chronological age and IQs. We found that with upright faces, children from both groups attended more to the eyes region than to the mouth region, and to the same extent. This pattern of behavior was observed for not only initial orientation of attention, but also when enough time was provided for attention to be disengaged from its initial locus. The present findings suggest that atypical face processing in autism does not result from abnormal attentional allocation to the different face parts.
