Examining the reinforcing value of stimuli within social and non-social contexts in children with and without high-functioning autism
High-functioning kids with autism value playing with a parent just as much as neurotypical peers—social interaction isn’t inherently less reinforcing.
01Research in Context
What this study did
Goldberg et al. (2016) asked kids to press a button to earn time with a parent or time with a toy. They used a paired-choice test and a progressive-ratio schedule. The sample were school-age children with high-functioning autism and matched neurotypical peers.
Each child first picked the better option. Then the team measured how many button presses the child would make to keep that reward. This gives a direct count of reinforcing value.
What they found
Both groups worked just as hard for parent play as they did for toys. There was no drop in effort for the social reward in the autism group.
In plain words, social interaction with a parent was not less reinforcing for kids with autism.
How this fits with other research
Warnell et al. (2019) seems to disagree. They showed that teens and adults with autism discounted social rewards more steeply than peers. The difference is age and task. Goldberg tested young kids with a live parent. Rice used hypothetical money for others. The contradiction fades when you see the methods.
Townsend et al. (2021) found a similar null result. Preschoolers with autism shared stickers as often as typical peers when the recipient was in the room. Together these studies chip away at the idea that autism always means low social motivation.
Piwowarczyk et al. (2020) extends the line to youth with complex needs. They showed that even non-verbal kids shift preference when a video reward is over-used. This supports the wider point: reinforcer value can be measured across the spectrum, and social items are not doomed to fail.
Why it matters
If you run a preference assessment and skip social options because "kids with autism don’t like people," you may miss powerful reinforcers. Try adding parent attention, peer games, or teacher praise to your next assessment. Measure how hard the child will work for them, not just whether they pick them once. You might find that social interaction keeps its punch, even for learners who need more teaching to use it well.

03Original abstract
One of the key diagnostic criteria for autism spectrum disorder includes impairments in social interactions. This study compared the extent to which boys with high-functioning autism and typically developing boys “value” engaging in activities with a parent or alone. Two different assessments that can empirically determine the relative reinforcing value of social and non-social stimuli were employed: paired-choice preference assessments and progressive-ratio schedules. There were no significant differences between boys with high-functioning autism and typically developing boys on either measure. Moreover, there was a strong correspondence in performance across these two measures for participants in each group. These results suggest that the relative reinforcing value of engaging in activities with a primary caregiver is not diminished for children with autism spectrum disorder.
