Inefficient and unique processing of social-emotional interference in school-aged children with high-functioning autism spectrum disorder.

Introduction: Interest is growing in investigating the ability of children with autism spectrum disorder (ASD) to process social information under conflicting and complex environments. However, few studies have employed objective behavioral measures to directly explore the underlying profile of social-emotional interference control. Methods: In the current study, 53 children with ASD and 53 typically developing (TD) control, aged 6-12 years, completed a set of modified flanker tasks involving arrows, schematic faces, same real faces (with facial interference by the same person), and different real faces (with facial interference by different people), respectively. Response time in incongruent (RT Results: We obtained three major results: (1) the ASD group had longer RT Conclusion: The current study delineates the inefficient processing of social-emotional interference in school-aged children with ASD and further suggests that these children might adopt a relatively optimized strategy like symbolization when dealing with emotional conflict. However, such compensatory cognitive strategies may be exhausted along with the increase in information load. These findings provide new perspectives of considering the difference more than difficulty in the cognitive profile of ASD, which will benefit the development of targeted behavioral interventions.
