Summary
Adolescents with autism primarily process faces using features, not holistic configuration. Most showed normal face recognition, but struggled with contextual face details, unlike typical individuals.
Area of Science:
- Neuroscience
- Developmental Psychology
- Cognitive Science
Background:
- Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by differences in social interaction and communication.
- Face processing in individuals with autism has been debated, with some research suggesting a more feature-based approach compared to holistic processing in neurotypical individuals.
Purpose of the Study:
- To investigate whether face processing in adolescents with autism is more feature-based than in typically developing individuals.
- To examine configural face processing using inversion and composite effects in high-ability adolescents with autistic disorder.
Main Methods:
- Two experiments were conducted using upright and inverted face and object images.
- Participants included 17 high-ability adolescents with autistic disorder, 24 typically developing children, and 16 adults.
- Standard face recognition paradigms and visual-search tasks were employed to assess face processing strategies.
Main Results:
- Adolescents with autism showed a normal inversion effect in face recognition, suggesting intact configural processing, except for a subgroup with low social intelligence.
- The autism group did not exhibit the composite effect, indicating reduced reliance on contextual face information during visual search, unlike the adult group.
Conclusions:
- Most adolescents with autism form normal configural face representations but are less inclined to use contextual face information in visual-search tasks.
- These findings suggest a nuanced profile of face processing in autism, with preserved configural abilities but diminished integration of holistic facial features.
