Global/local processing in autism: not a disability, but a disinclination.
Autistic kids can see the big picture when you tell them to — they just prefer details, so cue before you teach.
01Research in Context
What this study did
Koldewyn et al. (2013) watched autistic kids look at big shapes made of tiny shapes.
Sometimes the kids could look anywhere. Other times the team said, "Look at the big picture."
The study wanted to know if the children truly could not see the big shape, or simply liked the small ones.
What they found
When no one told them what to do, the kids stared at the tiny parts.
When the team said, "Look at the whole," the kids saw the big shape just fine.
The authors call this a disinclination, not a deficit — the ability is there, the choice is different.
How this fits with other research
Nayar et al. (2017) seems to disagree. They used eye-tracking and saw fewer looks at the big shape, claiming a real global perception gap. The clash fades when you notice they only watched free viewing, never giving the "look global" prompt that Kami used.
Burrows et al. (2018) and O'Connor et al. (2008) back Kami up. Both say the local bias is a default style, not a broken global system.
Alonso Soriano et al. (2015) found no local bias in teens with autism. The gap likely comes from age and from using computer-run tasks instead of human instructions.
Why it matters
Stop writing "global processing deficit" in reports. Instead note, "Client shows local preference that lifts with clear cue." Start sessions with a quick prompt: "First, look at the whole picture," then give the task. You may see instant gains in matching, puzzles, or social scenes that require whole-face reading.

03Original abstract
It is widely suggested that ASD is characterized by atypical local/global processing, but the published findings are contradictory. In an effort to resolve this question, we tested a large group of children on both a free-choice task and an instructed task using hierarchical local-global stimuli. We find that although children with autism showed a reduced preference to report global properties of a stimulus when given a choice, their ability to process global properties when instructed to do so is unimpaired. These findings support prior claims that people with ASD show a disinclination, not a disability, in global processing, and highlight the broader question of whether other characteristics of autism may also reflect disinclinations rather than disabilities.
