Sustained attention in children with autism.

Garretson et al. (1990) · Journal of autism and developmental disorders 1990
★ The Verdict

Poor attention scores in autism often signal low motivation, not a core deficit, so load tasks with reinforcers before labeling the child inattentive.

01Research in Context

01

What this study did

Researchers compared autistic and typical children on a long, boring computer task. They matched the groups by mental age, not birthday age.

The kids had to watch the screen and press a button when a special shape popped up. The session lasted several minutes to test staying power.

02

What they found

Autistic children missed more targets than their mental-age peers. The gap was big enough to notice, but the authors said it was about drive, not a broken attention muscle.

They wrote that the kids simply did not care enough about the plain game. Add fun rewards, they said, and scores would likely climb.

03

How this fits with other research

Anthony et al. (2020) followed the same idea into the teen years. They showed that autistic adolescents still ignore social rewards that usually pull in typical teens, backing the motivation story.

Dwyer et al. (2024) looked at toddlers and found no group gap in 'sticky' attention. Their eye-tracking data suggest the problem appears later, not at the start of life.

Fitzgerald et al. (2015) seems to clash at first: they found typical accuracy in autistic teens even while brain scans showed weak attention networks. The difference is method: behavior looked fine, but the brain worked harder, so both papers can be true.

Why it matters

Before you write 'attention deficit' in an IEP, check the task first. Swap in strong reinforcers, shorter trials, or the child's special interest. If scores jump, you have saved everyone from needless attention training and can target real goals like communication or play.

03Original abstract

Although many children with early infantile autism cannot maintain attention to externally imposed tasks, they may continue a repetitive behavior of their own choosing for long periods of time. This study examined the performance of autistic and mental age matched normal children on a Continuous Performance Test of sustained attention. Results suggest that autistic children's difficulties in sustaining attention on imposed tasks may be attributable partly to a developmental delay and partly to the motivational contingencies of task rather than to a primary impairment in the ability to sustain attention.
