Reward Devaluation in Autistic Children and Adolescents with Complex Needs: A Feasibility Study.
Kids with severe autism still get bored of overstuffed rewards, so keep reinforcers on rotation.
01Research in Context
What this study did
Piwowarczyk et al. (2020) asked a simple question. Can kids with severe autism show boredom with a reward?
They showed one favorite video or song over and over. Then they let the child pick between that tired item and a new one.
The team worked with youth who had complex needs—limited speech, low IQ, and multiple diagnoses.
What they found
The kids quickly lost interest in the over-played reward. They reached for the fresh item most of the time.
This drop in liking is called reward devaluation. It tells us the brain still updates value, even in severe autism.
How this fits with other research
Goldberg et al. (2016) saw a similar pattern. High-functioning kids with autism valued parent play the same as typical peers. Both studies show autism itself does not erase reward learning.
Warnell et al. (2019) looked almost opposite. They found teens and adults with autism discounted future and social rewards more steeply. The two papers seem to clash, but they test different rules. Anna tested short-term satiation; Rice tested long-term delay. Both can be true: kids get bored fast yet still undervalue distant pay-offs.
Knaier et al. (2023) reviewed dozens of tasks. Autistic people perform like neurotypicals on basic reward learning, but differ on metacognition and value-based choice. Anna’s result lands squarely in the “intact basic learning” column.
Why it matters
If a child can tire of a reward, you can use that. Rotate videos, songs, and toys every few minutes during teaching. Satiation becomes a cue to switch, not a roadblock. Keep a fresh bin ready and watch motivation stay high.

03Original abstract
Rewards act as a motivator for positive behavior and learning. Although compounding evidence indicates that reward processing operates differently in autistic individuals who do not have co-occurring learning disabilities, little is known about individuals who have such difficulties or other complex needs. This study aimed first to assess the feasibility of using an adapted reward devaluation paradigm to examine basic reward processes in this underrepresented population, and second to investigate whether autistic children and adolescents with complex needs would show dynamic behavioral changes in response to changes in the motivational value of a reward. Twenty-seven autistic children and adolescents with complex needs and 20 typically developing 5-year-old children took part in the study. Participants were presented with two visual cues on a touchscreen laptop, which triggered the delivery of a video, music, or physical reward. One of the rewards was then presented in abundance to decrease its motivational value. Participants showed decreased interest in the video and music rewards after devaluation. The experimental setup was found to be suitable to test individuals with complex needs, although recommendations are made for the use of physical rewards. The results suggest that autistic participants with complex needs demonstrate goal-directed behavior and that it is feasible to develop experimental paradigms that can shed important light on learning processes that are fundamental to many education and intervention strategies for this population.

LAY SUMMARY: We adapted an experimental task to conduct research with autistic children and adolescents with complex needs, who remain grossly underrepresented in autism research. We found that once a reward was presented in great quantity, participants were less motivated to obtain it, showing that they adapted their behavior to changes in the value of that reward. This is an important finding to help promote learning and design better interventions for this population.
