Autistic Adults Show Intact Learning on a Visuospatial Serial Reaction Time Task

Area of Science:

• Neuroscience
• Cognitive Psychology
• Developmental Psychology

Background:

• Theories suggest autistic individuals struggle with learning predictive relationships.
• Understanding procedural learning and predictive processing in autism is crucial.

Purpose of the Study:

• To investigate sequence-specific learning and predictive relationship acquisition in autistic adults.
• To compare learning abilities between autistic and neurotypical adults using a serial reaction time task.

Main Methods:

• A large-sample online study involving 61 autistic and 71 neurotypical adults.
• Utilized a serial reaction time task to assess the learning of repeating sequences.
• Measured reaction times and prediction-related errors.

Main Results:

• Autistic adults exhibited slower overall reaction times compared to neurotypical adults.
• Autistic adults demonstrated sequence-specific learning abilities comparable to neurotypical adults.
• Neurotypical adults made more prediction errors when sequences transitioned to random stimuli.

Conclusions:

• Autistic adults possess typical procedural memory and sequence-specific learning capabilities.
• Findings challenge theories positing general deficits in learning predictive relationships in autism.
• Subtle differences in the utilization of predictive information may exist in autistic adults.
