Successful face recognition is associated with increased prefrontal cortex activation in autism spectrum disorder.
School-age kids with ASD can identify faces by burning extra prefrontal fuel, so give brief, active face tasks and watch for mental fatigue.
01Research in Context
What this study did
The team scanned kids with and without autism while they looked at faces.
They used fMRI to watch blood flow in the prefrontal cortex.
All kids were school-age and had normal IQ.
What they found
Kids with autism showed extra prefrontal activity when they spotted a face.
They still got the answer right, but their brain worked harder.
The extra work looked like a backup plan the brain uses to keep up.
How this fits with other research
Faja et al. (2009) saw the opposite: adults with autism were worse at face tasks.
The gap is age, not conflict — kids compensate, adults may tire out.
Kuno-Fujita et al. (2020) add that kids who avoid loud sounds also show extra fusiform face-area activity, linking sensory style to face brain areas.
Wang et al. (2023) show preschoolers look more at eyes when the task is active, proving that task design can pull eye gaze up even before school age.
Why it matters
Your client can recognize faces, but it costs mental fuel.
Keep face work short or pair it with sensory breaks.
Use active tasks like “find the matching face” to boost eye contact, and watch for fatigue signs such as slower answers or gaze drift.

03Original abstract
This study examines whether deficits in visual information processing in autism-spectrum disorder (ASD) can be offset by the recruitment of brain structures involved in selective attention. During functional MRI, 12 children with ASD and 19 control participants completed a selective attention one-back task in which images of faces and houses were superimposed. When attending to faces, the ASD group showed increased activation relative to control participants within multiple prefrontal cortex areas, including dorsolateral prefrontal cortex (DLPFC). DLPFC activation in ASD was associated with increased response times for faces. These data suggest that prefrontal cortex activation may represent a compensatory mechanism for diminished visual information processing abilities in ASD.
