★ The Verdict

Robot drama play lifted joint attention and functional play in Mandarin preschoolers with autism.

01Research in Context

01

What this study did

So et al. (2020) ran a nine-week pilot with Mandarin-speaking preschoolers with autism. Half the kids got a robot-plus-human drama role-play. The rest waited. Staff tracked joint attention and play before and after.

02

What they found

The robot group started more joint attention and used toys in new ways. Parents also said their kids showed fewer social problems at home. The wait-list group stayed the same.

03

How this fits with other research

Zheng et al. (2020) tested robot joint-attention training with toddlers and saw no group gain. So et al. (2020) worked with slightly older preschoolers and got clear gains. Age may explain the split.

Chung et al. (2025) ran a larger 2025 RCT and found medium social gains with robots alone. Their stronger design now sets the bar, moving past this 2020 pilot.

Li et al. (2025) showed robots and humans are equal when teaching empathy with DTT. Wing-Chee adds drama play as another way robots can help.

04

Why it matters

If you serve preschoolers with ASD, try mixing a small robot into pretend-play scenes. Let the robot model actions, then fade to human peers. Track who starts eye-gaze or shared toy use. Nine short weeks may bring visible joint-attention growth and richer play without extra staff hours.

03Original abstract

Children with autism spectrum disorder (ASD) have deficits in joint attention and play behaviors. We examined whether a robot-based play-drama intervention would promote these skills. Chinese-speaking preschool children were randomly assigned to an intervention group (N = 12) and a waitlist control group (N = 11). Children in the intervention group watched three robot dramas and engaged in role-plays with both robots and human experimenters over the course of 9 weeks. There were significant improvements in joint attention initiations and functional play behaviors in the intervention group. Parents of this group of children also reported less severe social impairments. It was therefore concluded that a robot-based play-drama intervention can enhance the joint attention and play behaviors of children with ASD.
