Multiple Object Tracking Reveals Object-Based Grouping Interference in Children with ASD.
Kids with autism track moving, grouping objects just as well as typical peers.
01Research in Context
What this study did
Van der Hallen et al. (2018) watched kids chase moving dots on a screen.
Some kids had autism. Some did not.
The dots sometimes clumped together. The kids had to keep track of which dots were theirs.
What they found
Both groups tracked the dots equally well.
Even when the dots grouped, kids with autism stayed just as accurate.
No speed–accuracy trade-off showed up.
How this fits with other research
Wilkinson et al. (1998) once said kids across the autism spectrum look clumsy.
Ruth’s team shows one visuospatial job—tracking grouped objects—is not the cause of that clumsiness.
Iarocci et al. (2004) also found no attention gap in autism on a sudden-cue task.
Together these null results tell us basic attention and tracking hardware is intact; the trouble lies elsewhere.
Why it matters
You can stop assuming kids with autism will lose track of moving objects during lessons or games.
Use fast-moving group activities without extra supports; the visual skill is already there.
Save your teaching time for social or motor goals that truly need help.

03Original abstract
The multiple object tracking (MOT) paradigm has proven its value in targeting a number of aspects of visual cognition. This study used MOT to investigate the effect of object-based grouping, both in children with and without autism spectrum disorder (ASD). A modified MOT task was administered to both groups, who had to track and distinguish four targets that moved randomly amongst four distracters, irrespective of the grouping condition. No group difference was revealed between children with and without ASD: both showed adequate MOT abilities and a similar amount of grouping interference. Implications of the current result are considered for previous MOT studies, the developmental trajectory of perceptual grouping, and the idea of heightened sensitivity to task characteristics in ASD.
