Joint intention understanding in children with autism spectrum disorder.
Kids with ASD may watch social play but still miss the shared goal—ask them to state it aloud.
01Research in Context
What this study did
The team showed short videos to the preschoolers. Half had autism. Half were typical.
Each clip showed two people building a toy together. The camera tracked where kids looked.
After each clip the child answered two questions. “What were they making together?” “What will she do next?”
What they found
Typical kids named the shared goal and next move far better than autistic kids.
Both groups looked at the same faces and hands. Eye gaze was equal.
Looking without understanding is the gap. Kids with ASD watched but missed the shared plan.
How this fits with other research
Downs et al. (2004) once saw high-functioning autistic children cooperate as well as peers. The new study shows younger, mixed-functioning preschoolers cannot. Age and level matter.
Smith et al. (2010) already showed autistic kids lag on “see-know” theory-of-mind tasks. Hou et al. (2023) now proves the lag starts even earlier, at the joint-intention step.
Roane et al. (2001) found teens with Asperger’s struggle with real-life social problems. The preschool gap seen here likely feeds those later struggles.
Why it matters
You can close the gap by making shared goals obvious. Use clear labels: “We are building a castle.” Point and narrate each partner’s role. Check understanding with quick questions: “What are we making?” Eye tracking tells us kids look engaged—so don’t trust looks alone. Test comprehension every few minutes during social play.

03Original abstract
This study examined the ability of children with autism spectrum disorder (ASD) to generate joint intention-based action prediction in a joint action task. Children were presented with a series of videos in which two actors either played with blocks based on joint intention (social condition) or played with blocks independently (nonsocial condition). In the familiarization stage, two actors demonstrated how they played with blocks three times. In the test stage, one actor left the scene, and another actor grasped a block and asked where she should place it. Children's gaze behavior was assessed by an eye tracker. After watching videos, children were asked to answer two questions: an action prediction question and an intention understanding question. The results showed that in the implicit eye movement task, children with ASD and typically developing (TD) children exhibited location-based anticipatory gaze under both conditions. However, in terms of explicit behavioral responses, TD children showed higher accuracy in response to action prediction questions and intention understanding questions than children with ASD in the social condition, while no significant group difference was found in the nonsocial condition. These results indicate that children with ASD have difficulty understanding joint intention and that their action prediction is primarily driven by bottom-up sensory inputs.
