Judgments of cause and blame: sensitivity to intentionality in Asperger's syndrome.
Adults with Asperger’s judge physical cause like anyone else, but they lean more heavily on intent when deciding who deserves blame.
01Research in Context
What this study did
Channon et al. (2011) asked the adults with Asperger’s and 24 typical adults to read short stories. Each story described an action that hurt someone.
Some actions were on purpose. Some were accidents. After every story, adults rated how much the actor caused the harm and how much they should be blamed.
What they found
Both groups gave the same cause ratings. They saw the actor as equally responsible for the outcome.
When blaming, adults with Asperger’s paid extra attention to the actor’s intent. If the harm was accidental, they gave less blame than typical adults. If it was on purpose, they gave more blame.
How this fits with other research
Kaufman et al. (2010) found that children with intellectual disability often misread intent. Shelley’s adults with Asperger’s did not misread; they just used the intent data differently when assigning blame.
Luckasson et al. (2017) showed intact visual attention in ASD. Shelley adds another intact skill: judging physical cause. The difference shows up only in the social-moral layer of blame.
Némorin et al. (2025) split children with ASD into four subtypes. Shelley’s finding warns that adults with ASD can also show unique social-cognitive patterns that average scores might hide.
Why it matters
When you probe social understanding, separate cause from blame. Your client may track who did what correctly yet surprise you with harsher or softer moral ratings. Use clear intent statements in social stories and check how the learner weighs them before teaching perspective-taking skills.

03Original abstract
Sensitivity to intentionality in people with Asperger's syndrome (AS) and matched controls was investigated using two scenario-based tasks. The first compared intentional and unintentional human actions and physical events leading to the same negative outcomes. The second compared intentional actions that varied in their subjective and objective likelihood of bringing about a negative outcome. Whilst adults with AS did not differ from controls in their judgments of causality, or in their blame judgments in relation to non-mentalistic factors, they showed heightened sensitivity to mentalistic considerations in their attributions of blame. They made greater differentiation than controls between intentional and unintentional actions, and also between actions that the protagonists believed to be likely versus unlikely to lead to negative consequences.
