Super responders: Predicting language gains from JASPER among limited language children with autism spectrum disorder.
Count how many ways a preschooler with autism plays with toys—more variety flags the kids who will rocket in expressive language after JASPER.
01Research in Context
What this study did
Ee et al. (2022) looked at which preschoolers with autism blow up in expressive language after JASPER play sessions. They watched how many different ways each child played with toys before therapy started.
The team ran a simple pre-post study. They gave all kids the same JASPER package—joint attention, pretend play, and regulation games—then tracked who became a 'super responder' in spoken words.
What they found
Kids who used more toy functions at baseline—like rolling, stacking, and pretending—were the ones who later surged in expressive language. Play diversity acted like a quick screen for big language pay-offs.
The finding held for children who began with almost no words. More flexible play equaled bigger language jumps after the same dose of JASPER.
How this fits with other research
Chang et al. (2016) already showed that JASPER works in real preschool classrooms. Jonathan now adds a practical rule: check play diversity first so you know which kids will drive those gains.
Green et al. (1987) and Bachman et al. (1988) launched natural-language teaching in play with varied toys and proved it beats tabletop drills. Jonathan confirms the toy variety angle still matters decades later, but turns it into a predictor, not just a method.
Mason et al. (2021) asked clinicians to guess which fine pre-linguistic signs forecast speech. Jonathan gives a concrete, 5-minute play count that does the forecasting for you.
Why it matters
Before you write a long-term language goal, watch the child play with five ordinary toys for five minutes. If you see at least four different actions, plan for a fast language track and add extra vocabulary targets. If play is repetitive, keep the same JASPER steps but expect slower, steadier growth and layer in more mand training. Either way, you match dosage and parent expectations from day one.

03Original abstract
Early intervention can provide a great benefit for children with autism spectrum disorder (ASD). However, no single intervention is effective for all children. Even when an intervention is effective overall, individual child response varies. Some children make incredible progress, and others make slow or no progress. Therefore, it is important that the field move towards developing methods to personalize intervention. Operationalizing meaningful change and predicting intervention response are critical steps in designing systematic and personalized early intervention. The present research used improvement in expressive language to group children that received a targeted social communication early intervention, Joint Attention, Symbolic Play, Engagement, and Regulation (JASPER), into super responders and slow responders. Using baseline data from traditional standardized assessments of cognition and behavioral data from validated experimental measures of play and social communication, we used conditional inference tree models to predict responder status. From a sample of 99 preschool age, limited language children with ASD, play diversity was the most significant predictor of responder status. Children that played functionally with a wider variety of toys had increased odds of being a super responder to JASPER. A combination of lower play diversity and impairments in fine motor abilities increased the odds of children being slow responders to JASPER. Results from the present study can inform future efforts to individualize intervention and systematic approaches to augmenting treatment in real time. LAY SUMMARY: To help us answer the question of for whom an intervention works best, we examined 99 children, age three to five, who qualified as being limited spoken language communicators, and received a targeted intervention for social communication and language. We used child characteristics before intervention to predict which children would improve their language the most and found that the ability to play appropriately with a wider variety of toys predicted the best improvements in expressive language. These findings will help better inform future work to individualize intervention based on the unique needs of each child.
