Brain Activity Patterns Distinguish Autistic Teens Who Mask Socially
New research reveals how brain activity differs in autistic teens who mask their diagnosis, with faster responses to faces and reduced emotional reactivity—offering insights into the mental effort behind social masking.
Recent research from Drexel University's A.J. Drexel Autism Institute has uncovered notable differences in brain activity among autistic teenagers who engage in social masking—behaviors used to appear non-autistic in social settings. Masking helps these teens blend in, but until now, little was known about how their brains function during social interactions.
Using electroencephalogram (EEG) technology, the study found that teens who pass as non-autistic in classroom environments exhibit faster neural responses when processing facial cues and show reduced emotional reactions to subtle facial expressions. This suggests that their brains may be wired to quickly recognize social signals while dampening emotional responses, possibly as a coping strategy.
The study revealed that approximately 44% of autistic teens recruited from the community appeared to pass as non-autistic according to their teachers, despite meeting criteria for autism through formal assessments. Their rapid initial brain responses faced less emotional reactivity upon seeing faces with subtle emotional expressions.
These findings shed light on the unique ways in which brain mechanisms operate in autistic teens who mask their diagnosis. Such insights are crucial for understanding the mental efforts involved in masking, which can contribute to emotional and cognitive strain.
Led by Dr. Matthew Lerner, the research indicates that these neural differences may reflect distinct cognitive processing strategies in teens who mask their autism, differing from both non-autistic and non-masking autistic peers. The study, published in Scientific Reports, was part of a larger effort supported by the National Institute of Mental Health to explore factors influencing social outcomes in autistic youth.
The research involved analyzing event-related potentials (small brain activity responses to stimuli) while participants rated facial emotions. The results provide a foundation for further study into how autistic individuals who mask navigate social environments, with potential implications for tailored support strategies.
This pioneering work emphasizes the importance of identifying and supporting autistic youth who may not outwardly display typical autistic traits, highlighting the diversity within the autism spectrum.
