Driving Simulator Performance in Novice Drivers with Autism Spectrum Disorder: The Role of Executive Functions and...

Area of Science:

• Neurodevelopmental disorders
• Cognitive psychology
• Traffic safety research

Background:

• Individuals with autism spectrum disorder (ASD) often exhibit impaired driving performance compared to neurotypical peers.
• Limited research exists on the specific cognitive factors contributing to driving challenges in ASD novice drivers.

Purpose of the Study:

• To investigate the association between driving performance and executive functioning in novice drivers with and without ASD.
• To identify specific executive functions that may underlie driving difficulties in individuals with ASD.

Main Methods:

• Utilized a driving simulator to assess driving skills in male novice drivers aged 15-23.
• Administered executive functioning tasks, including a working memory paradigm.
• Compared performance between 17 participants with ASD and 27 healthy controls.

Main Results:

• Drivers with ASD demonstrated significantly poorer overall driving performance.
• The introduction of a working memory task led to a marked decline in driving performance for ASD drivers compared to controls.
• Executive functioning, particularly working memory, is strongly linked to driving performance in this cohort.

Conclusions:

• Working memory deficits appear to be a critical factor contributing to the driving impairments observed in individuals with ASD.
• Findings offer valuable insights for developing targeted intervention strategies to improve driving abilities for ASD novice drivers.
• This research highlights the importance of assessing executive functions in the context of driving safety for individuals with ASD.
