Visual processing in adolescents with autism spectrum disorder: evidence from embedded figures and configural superiority tests.

Dillen et al. (2015) · Journal of autism and developmental disorders 2015
★ The Verdict

Teens with ASD process visual scenes the same as their peers—no special local bias detected.

✓ Read this if BCBAs running skill assessments with teens in clinic or schools.
✗ Skip if Clinicians working only with adults or very young children.

01Research in Context

01

What this study did

Researchers tested 28 teens with ASD and 28 typical teens.

They used two computer tasks: find hidden shapes and spot odd patterns.

Each teen sat alone at a screen and clicked answers.

02

What they found

Both groups scored the same on both tasks.

ASD teens did not zoom in on tiny details more than peers.

They also did not miss the big picture when shapes changed.

03

How this fits with other research

Geurts et al. (2008) saw ASD kids beat peers on hidden-figure tasks. Alonso Soriano et al. (2015) now shows no edge in teens. The gap likely shrinks with age.

Dolezal et al. (2010) found that college students with more autistic traits solved hidden figures faster. Claudia’s null result in diagnosed teens shows the trait effect may not hold once ASD is clinical.

Iarocci et al. (2006) hinted that task rules, not vision, drive earlier mixed results. Claudia’s clean null supports this: when the task is simple, ASD teens see like anyone else.

04

Why it matters

You can stop assuming teens with ASD will always spot tiny details faster. Use the same visual prompts, checklists, and room set-ups you use for all teens. If a client struggles, look at attention or motivation, not a built-in visual style.

03Original abstract

The embedded figures test has often been used to reveal weak central coherence in individuals with autism spectrum disorder (ASD). Here, we administered a more standardized automated version of the embedded figures test in combination with the configural superiority task, to investigate the effect of contextual modulation on local feature detection in 23 adolescents with ASD and 26 matched typically developing controls. On both tasks both groups performed largely similarly in terms of accuracy and reaction time, and both displayed the contextual modulation effect. This indicates that individuals with ASD are equally sensitive compared to typically developing individuals to the contextual effects of the task and that there is no evidence for a local processing bias in adolescents with ASD.
