Characterizing Attention Resource Capacity in Autism: A Multiple Object Tracking Study.
Domenico Tullo, Bianca Levy, Jocelyn Faubert and 1 others
PMID 37344729WHAT IT FOUND
On a standard attention test, autistic and neurotypical participants did not differ.
Tracking speed was lower in autistic participants, but that difference disappeared after fluid reasoning IQ was included.
Key findings
01On the primary attention test, the autistic and neurotypical groups did not differ.
02Autistic participants tracked objects at slower speeds than neurotypical participants overall, but the group difference was no longer significant after fluid reasoning IQ was included.
03Fluid reasoning IQ predicted tracking speed, while CPT-3 attention score and verbal IQ did not.

What it does not show
The study excluded autistic participants with ADHD or attention deficits, so it does not speak to many clients who have both conditions. The autism and neurotypical groups differed in IQ and sex, and the autism sample came from a hospital and a specialized school rather than the community. Autism community members were not involved in the study. The intellectual-style analysis used 14 participants in each cell and had limited power. The primary attention test was null, so the study does not show an autism-specific difference on that measure.
The easy way to misread this
Do not read the lower MOT speed in autistic participants as an autism-specific attention deficit. The primary attention test showed no group difference, and the MOT group difference disappeared when fluid reasoning IQ was included.
