Atypical Scene-Selectivity in the Retrosplenial Complex in Individuals With Autism Spectrum Disorder.

Agiovlasitis et al. (2025) scanned adults with autism while they looked at pictures of places. The team focused on the retrosplenial complex, a brain area that normally lights up for scenes and helps us find our way.

They compared the scene response to that of typical adults. The goal was to see if weaker brain activity here could explain why some autistic people struggle with map reading or learning new routes.

The autism group showed a smaller jump in RSC activity when viewing scenes. A second scene area, the OPA, looked the same in both groups, so the problem is specific to the RSC.

The authors link this dampened signal to trouble using past spatial memories to guide navigation.

The result lines up with two earlier studies. Baharav et al. (2008) saw slower detection of odd objects in real-world photos, and Andrews et al. (2024) reviewed papers showing that building mental scenes is hard for many autistic individuals. All three point to a weak top-down picture of space.

Yet Hochhauser et al. (2018) seems to say the opposite: adolescents with autism spotted scene changes faster than typical teens. The difference is age and task. The 2018 kids were young and had extra time; the 2025 adults were older and viewed rapid streams. Speed demands may unmask the RSC gap.

O'Connor et al. (2008) adds that face areas are also under-active in autism. Together the papers sketch a ventral-stream trade-off: faces and places both get less specialized processing.

If a client gets lost easily, the issue may be neural, not careless. Teach routes with extra landmarks, verbal scripts, or GPS cues instead of paper maps alone. Rehearse the same path several times to build a stronger picture. And give processing time—quick scene tasks may under-estimate what they know.
