Autistic Adults are Not Impaired at Maintaining or Switching Between Counterfactual and Factual Worlds: An ERP Study.

This study tested whether autistic adults can think about 'what if' situations and switch back to reality. Researchers had 48 people read stories about real and imaginary situations, then tested their understanding. Autistic adults performed just as well as non-autistic adults at keeping track of different scenarios and switching between them, even though they showed some difficulties with other thinking skills. This suggests autistic people are good at this type of complex reasoning.

This ERP study examined whether autistic adults (N=48) can maintain and switch between counterfactual and factual mental representations. Participants read scenarios establishing factual or counterfactual contexts, then either maintained the counterfactual world or switched back to factual reality. Results showed autistic adults performed similarly to neurotypical controls in detecting inconsistencies within maintained contexts and managing interference when switching between counterfactual and factual worlds. These cognitive abilities remained intact despite group-level impairments in Theory of Mind and cognitive flexibility among autistic participants.

The findings demonstrate preserved capacity for complex contextual reasoning and mental representation updating in autism.

Results suggest autistic individuals may have stronger counterfactual reasoning abilities than traditionally assumed. This challenges stereotypes about cognitive rigidity in autism and may inform more nuanced approaches to cognitive assessment and intervention planning that recognize preserved strengths alongside documented difficulties.

Single study design with moderate sample size. Study type not specified in metadata. Limited generalizability without replication. ERP methodology may not capture all aspects of counterfactual reasoning. Unclear how findings translate to real-world counterfactual thinking scenarios.

We report an event-related brain potential (ERP) experiment that tests whether autistic adults are able to maintain and switch between counterfactual and factual worlds. Participants (N = 48) read scenarios that set up a factual or counterfactual scenario, then either maintained the counterfactual world or switched back to the factual world. When the context maintained the world, participants showed appropriate detection of the inconsistent critical word. In contrast, when participants had to switch from a counterfactual to factual world, they initially experienced interference from the counterfactual context, then favoured the factual interpretation of events.

None of these effects were modulated by group, despite group-level impairments in Theory of Mind and cognitive flexibility among the autistic adults. These results demonstrate that autistic adults can appropriately use complex contextual cues to maintain and/or update mental representations of counterfactual and factual events.
