Brief report: face configuration accuracy and processing speed among adults with high-functioning autism spectrum...

Area of Science:

• Cognitive Neuroscience
• Neurodevelopmental Disorders
• Autism Spectrum Disorders (ASD) Research

Background:

• Autism Spectrum Disorder (ASD) is a neurodevelopmental condition impacting social interaction and communication.
• Previous research indicates differences in face processing in children with ASD, but adult patterns are less understood.
• Understanding face processing in adults with ASD is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate the accuracy and speed of face processing in high-functioning adults with ASD.
• To compare holistic versus featural face processing in adults with ASD and neurotypical controls.
• To examine sensitivity to configural information and feature distances in face recognition tasks.

Main Methods:

• Two behavioral experiments were conducted with high-functioning adults with ASD and neurotypical controls.
• Tasks measured sensitivity to inter-feature distances and face recognition accuracy and speed.
• Stimuli varied in reliance on holistic versus featural information and second-order configural changes.

Main Results:

• Adults with ASD were less accurate but equally fast as controls in holistic and featural face processing tasks.
• A holistic processing advantage in adults with ASD was observed only when the eye region was manipulated.
• Controls were faster than participants with ASD in recognizing large changes to configural information.

Conclusions:

• Adults with ASD exhibit distinct face processing patterns compared to neurotypical individuals and children with ASD.
• The findings suggest a developmental trajectory in holistic face processing within the autism spectrum.
• Impaired configural processing may contribute to social-communication challenges in adults with ASD.
