Gestalt perception and local-global processing in high-functioning autism.

Bölte et al. (2007) asked adults with high-functioning autism and typical adults to look at big shapes made of tiny shapes.

The task: name the big shape as fast as possible.

The team wanted to know if the autism group would spot the whole picture as quickly as the small parts.

The autism group was slower and less accurate at seeing the big shape.

They showed a clear local-first style: eyes locked onto the tiny pieces and missed the overall pattern.

Nayar et al. (2017) saw the same global weakness in autistic children using eye-tracking, so the issue starts early and lasts.

Storch et al. (2012) looks like a clash: young autistic adults switched between big and small shapes just as fast as controls. The gap may close in the 18-25 range, then reopen later.

Alonso Soriano et al. (2015) also found no local bias in autistic teens, hinting the picture keeps changing with age and task type.

When you show visual schedules, social stories, or video models, start with the key whole picture first. Add small details only after the learner sees the main idea. This small tweak can cut confusion for clients who get stuck on pieces instead of the whole scene.
