Is visual gaze in children with autism spectrum disorder related to sequence of emotion intensity presentation? An eye-tracking study of natural emotion perception processes.
Start emotion lessons with low-intensity faces and build to high for better gaze and naming in kids with autism.
01Research in Context
What this study did
Duan and colleagues tracked where the children with autism and 30 typical peers looked while watching faces show emotions. The faces appeared in two orders: weak-to-strong (happy grows from slight smile to big grin) or strong-to-weak (big grin fades to slight smile). Eye cameras recorded every glance.
The team wanted to know if the simple trick of order helps kids with autism catch feelings better.
What they found
When emotions grew from weak to strong, children with autism looked longer at the eye and mouth regions and correctly named more feelings. Typical kids did the same in both orders.
The weak-to-strong sequence acted like a gentle ramp, letting autism eyes lock on before the full emotion hit.
How this fits with other research
Lemons et al. (2015) saw no gaze aversion in preschoolers with autism during mutual gaze. The new study agrees: the kids could look; they just needed the right sequence. Age matters—toddlers may not need the ramp, but school-age kids benefit.
Zhao et al. (2023) found Chinese children with autism looked away from mouths during real chat. Duan’s lab task shows the same group can re-focus if we control the pace and start small.
Root et al. (2017) showed kids with autism miss low-intensity anger. Duan’s weak-to-strong order fixes that exact problem by first showing the subtle hint, then building up.
Why it matters
Next time you run social-skills group, open with mild smiles and grow to big ones. The five-second ramp lets autism eyes warm up, locks attention on the key features, and boosts correct emotion labels without extra toys or prompts. Cheap, fast, and it fits any tablet.

03Original abstract
Emotion cognitive remediation is a critical component of social skills training for children with autism spectrum disorder (ASD). Visual perception of emotions is highly correlated with the intensity and sequence of presented emotions. However, few studies examined the effect of presentation sequence and intensity on emotion perception. The present study examined the gaze patterns of children with ASD in receiving different sequences of emotion presentation using eye-tracking technologies. Gaze patterns of ecologically-valid video clips of silent emotion stimuli by 51 ASD children and 34 typically developing (TD) children were recorded. Results indicated that ASD and TD children showed opposite visual fixation during different intensity presentation modes: children with ASD showed better emotion perception with a weak-to-strong emotion sequence when presented. The visual reductions in emotion perception in children with ASD may due to different perceptual threshold to emotional intensity. The extent of the reductions could be related to an individual's Personal-Social ability. The present study supports the importance of intensity of emotions and the order at which the emotional stimuli were presented in yielding better emotion perceptions in children with ASD, suggesting that the order of emotion presentation may potentially influence emotion processing during ASD rehabilitation. It is anticipated that the present findings could bring more insights to clinicians for intervention planning in the future.
