Reduced goal-directed action control in autism spectrum disorder.
Autistic adults keep "working" for rewards that no longer matter, showing a stubborn goal system that may feed everyday repetitive behaviors.
01Research in Context
What this study did
The team tested the adults with autism, 24 with social anxiety, and 24 typical adults. Each person first learned that pressing a key earned salty popcorn or chocolate candy. Next they ate one snack until they said "I'm full." Finally they were free to press for more food.
The question: after satiety, would the adults stop pressing for the now-worthless snack? The task measures goal-directed control — the ability to quickly adjust behavior when outcomes lose value.
What they found
Typical adults almost stopped pressing for the food they had just stuffed themselves with. The autism and social-anxiety groups kept pressing at the original high rate. Their hands kept "working" even though the reward no longer mattered.
The result shows sticky, inflexible action control — a possible engine for the repetitive behaviors seen in autism.
How this fits with other research
Green et al. (2020) extends the story to movement. They found autistic adults also stay shaky and inaccurate when learning new arm reaches, pointing to planning and force-control problems beyond food rewards.
Cramm et al. (2009) seems to contradict: they watched autistic kids' stereotypies stop on their own without adult help. The difference is method — M et al. watched natural behavior, while A et al. tested lab control. Both can be true: real-world habits may extinguish spontaneously, yet lab measures still reveal rigid goal systems.
Sabatino et al. (2013) adds brain evidence. Using fMRI they showed weaker frontostriatal signals when autistic people process nonsocial rewards, matching the behavioral rigidity A et al. caught on camera.
Why it matters
If your client keeps lining up toys long after the game is fun, the issue may be a stuck goal system, not stubbornness. Build interventions that explicitly re-value outcomes: let the child taste, smell, or play with the "finished" item again, then prompt a new action. Short satiation trials followed by clear choice-making can teach flexible stopping — a skill that generalizes beyond snacks to rituals and routines.

03Original abstract
Autism spectrum disorder (ASD) is a group of heterogeneous neurodevelopmental conditions associated with persistent, stereotyped or repetitive actions, and patterns of interest that are maintained in spite of possible negative outcomes. The aim of the present study was to investigate whether impairments in the ability to execute flexible goal-directed actions may be an underlying feature in ASD contributing to these symptoms. Young adults diagnosed with ASD were recruited along with controls and adults with social anxiety disorder (SAD). Participants were trained to make keyboard actions for food outcomes and then subsequently allowed to consume one outcome till satiety. As expected, this outcome devaluation procedure reduced subsequent responding for actions predicting the devalued outcome, while maintaining responding on the other still-valued action, in controls. However, both ASD and SAD participants were unable to demonstrate flexible goal-directed actions, and were insensitive to the change in outcome value on subsequent action control. This behavioral deficit was not due to impairments in appropriate contingency awareness, as all groups rated the devalued food outcome as less pleasant after devaluation. A lack of control over actions may underlie persistent and habitual actions in anxiety-inducing contexts typical in both ASD and SAD, such as avoidance and safety behaviors. Using a translational behavioral paradigm, this study demonstrated that individuals with ASD are unable to use changes in the environment to flexibly update their behavior in the same context. This reduced behavioral control may underlie persistence of intrusive actions and restricted inflexible cognition, representing a specific area for targeted behavioral interventions.
