Communication deficits in children with autism spectrum disorders (ASD) are often related to inefficient interpretation of emotional cues, which are conveyed visually through both facial expressions and body language. The present study examined ASD behavioral and ERP responses to emotional expressions of anger and fear, as conveyed by the face and body. Behavioral results showed significantly faster response times for the ASD than for the typically developing (TD) group when processing fear, but not anger, in isolated face expressions, isolated body expressions, and in the integration of the two. In addition, EEG data for the N170 and P1 indicated processing differences between fear and anger stimuli only in TD group, suggesting that individuals with ASD may not be distinguishing between emotional expressions. These results suggest that ASD children may employ a different neural mechanism for visual emotion recognition than their TD peers, possibly relying on inferential processing.
Abstract. An understanding of the relationship between emotions, cognition, and learning can provide insight into learning needs for children with autism spectrum disorder (ASD). This article discusses current research and new theories on ASD from three different perspectives: the behavioral sciences, neuroscience, and education. The rapid increase of ASD diagnoses in children worldwide, and an understanding of autism as one of the developmental disorders affecting a spectrum of neural networks in a growing brain, indicates that educational implications from the combined insights may strengthen the development of strategies and interventions not only for ASD individuals, but for neurotypical children as well.
