Autistic Adults Anticipate Simple and Complex Narrative Events

Area of Science:

• Cognitive Neuroscience
• Developmental Psychology
• Autism Research

Background:

• Narrative comprehension relies on predicting future events based on causal connections.
• Autistic adults exhibit atypicalities in narrative cognition, necessitating further investigation into their predictive abilities.

Purpose of the Study:

• To investigate event anticipation in narratives among autistic adults compared to neurotypical adults.
• To explore how autistic adults process simple (factual) and complex (counterfactual) narrative events in social and non-social contexts.

Main Methods:

• Utilized the visual world paradigm with 25 autistic and 25 neurotypical adults.
• Tracked eye movements while participants listened to social and non-social narratives with varying contextual complexity.
• Presented participants with visual stimuli depicting potential narrative outcomes.

Main Results:

• Autistic adults showed delayed anticipation of simple non-social events but faster anticipation of complex non-social events.
• In social narratives, autistic adults were faster at anticipating simple events, while neither group anticipated complex events well.
• Neurotypical adults demonstrated stronger real-world knowledge constraints, influencing their anticipation of narrative events.

Conclusions:

• Autistic adults can anticipate narrative events but inconsistently across types, with challenges not limited to social contexts.
• Autistic adults employ distinct predictive strategies, being less grounded in reality and more open to imagined alternatives.
• Findings suggest differences in predictive processing and reliance on real-world knowledge in autistic adults' narrative comprehension.
