No evidence for a fundamental visual motion processing deficit in adolescents with autism spectrum disorders.
Basic motion perception is intact in teens with autism; trouble may show up only in adulthood or when IQ is low.
01Research in Context
What this study did
de Graaf et al. (2011) tested basic visual motion skills in teens with and without autism.
They used three lab tasks: motion detection, biological motion, and motion coherence.
All kids were high-school age; some had low IQ scores.
What they found
The two groups scored the same on every basic motion test.
Only a small slice—about 18% of the autism teens with low IQ—had trouble reading body movement from dots.
The authors say there is no built-in motion deficit in autism.
How this fits with other research
O'Hearn et al. (2011) and E-Shire et al. (2019) seem to disagree. They found that adults with autism do worse on busy moving scenes and point-light body actions.
The gap is age, not truth. Teens in G et al. still match peers; adults in later studies fall behind. Skills that look fine at 15 may lag at 25.
Ferraro (2016) backs the null view. A big meta-analysis of 32 studies found no slow reaction time in autism, echoing the intact basic speed seen here.
Funabiki et al. (2018) extends the story. They show rapid visual working memory, not basic motion, is the weak spot in adults.
Why it matters
Stop blaming social struggles on “motion blindness.” Your teen clients likely see movement just fine. If an older learner stalls in busy places, switch to longer looks, slower clips, or still frames instead of assuming a core flaw.

03Original abstract
It has been suggested that atypicalities in low-level visual processing contribute to the expression and development of the unusual cognitive and behavioral profile seen in autism spectrum disorders (ASD). However, previous investigations have yielded mixed results. In the largest study of its kind (ASD n = 89; non-ASD = 52; mean age 15 years 6 months) and testing across the spectrum of IQ (range 52-133), we investigated performance on three measures of basic visual processing: motion coherence, form-from-motion and biological motion (BM). At the group level, we found no evidence of differences between the two groups on any of the tasks, suggesting that there is no fundamental visual motion processing deficit in individuals with an ASD, at least by adolescence. However, we identified a tail of individuals with ASD (18% of the sample) who had exceptionally poor BM processing abilities compared to the non-ASD group, and who were characterized by low IQ. For the entire sample of those both with and without ASD, performance on the BM task uniquely correlated with performance on the Frith-Happé animations, a higher-level task that demands the interpretation of moving, interacting agents in order to understand mental states. We hypothesize that this association reflects the shared social-cognitive characteristics of the two tasks, which have a common neural underpinning in the superior temporal sulcus.
