Evidence for a cultural influence on field-independence in autism spectrum disorder.
Field-independence in autism disappears in Singapore, so culture must guide your visual-assessment norms.
01Research in Context
What this study did
Koh et al. (2012) gave the Embedded Figures Test to two groups of children. One group lived in England. The other group lived in Singapore. All children were about six to eight years old. Some had autism. Some did not.
The task is simple: find a small shape hidden inside a bigger picture. Kids with autism in the West usually finish faster. The team wanted to know if this "field-independence" effect shows up in East-Asian culture too.
What they found
English children with autism found the hidden shape faster than English peers without autism. Singaporean children with autism did not beat their Singaporean peers. Culture flipped the usual result.
The data say weak central coherence is not a universal autism trait. It appears only in certain cultures.
How this fits with other research
Kaland et al. (2007) ran the same test in the United Kingdom and also saw no speed edge for kids with ASD. Their null result now matches the Singaporean data in Koh et al. (2012).
Riches et al. (2016) tested weak central coherence with sentences, not pictures. They found no autism difference either. Three studies, three nulls — the theory keeps coming up empty.
Pitchford et al. (2019) widened the lens. They showed parent autism ratings stay steady across cultures while teacher ratings swing. Together these papers warn us: culture shapes both test scores and who gets noticed.
Why it matters
Before you label a child as "detail-focused" or "field-independent,” ask where the family comes from. A fast Embedded Figures score in London may mean autism. The same score in Singapore may only mean typical development. Use local norms, not Western ones, when you interpret visual tasks.

03Original abstract
Field-independence, or weak central coherence, is a recognised phenotype of autism spectrum disorder (ASD). There is also evidence of cultural variation in this perceptual style, as neurotypical individuals from Western nations are more field-independent than neurotypical individuals from East-Asian nations. The majority of research on perceptual style in those with ASD has been carried out in Western nations therefore it is unclear whether increased field-independence in ASD is a culturally universal phenotype. Here, we assessed perceptual style in children with and without ASD from England and Singapore using the Children's Embedded Figures Test and the Framed-Line Test. We found increased field-independence in the English participants with ASD only, suggesting that weak central coherence in ASD is not culturally universal.
