Assessment & Research

Adults' versus children's perceptions of a child with autism or attention deficit hyperactivity disorder.

Harnum et al. (2007) · Journal of autism and developmental disorders 2007
★ The Verdict

Kids aged 7–12 reject peers with autism or ADHD more strongly than adults, so brief peer teaching should start early.

✓ Read this if BCBAs planning school inclusion or social-skills groups for late-elementary students.
✗ Skip if Clinicians who work only with toddlers or adults.

01Research in Context

01

What this study did

The team asked kids and grown-ups to read short stories. Each story described a child who acted in ways linked to autism or ADHD.

After reading, people answered questions about how much they liked the child and whether they would play with them.

The sample included children aged 7–12 and adults. All listeners saw the same stories, so answers could be compared directly.

02

What they found

Children said they liked the story child less and would avoid them more than adults did.

Both kids and adults felt the autistic child was “not like me.” Only kids felt the ADHD child was very different.

In short, elementary students were harsher judges than grown-ups.

03

How this fits with other research

DeRoma et al. (2004) ran a small trial and showed that giving peers a short “why” explanation raised acceptance. Their positive result hints that kids can soften their views if we teach them.

Nicholson et al. (2017) later asked students to judge exclusion. Most said leaving a classmate with autism out is wrong. This seems to clash with the new data, but Kristen used open questions about fairness, not liking ratings, so the measures differ.

Whaling et al. (2025) moved the question to college students. They found that young adults often blame ADHD, not autism, for odd behavior. Together the papers trace a line: child peers dislike, teen peers pity, adult peers mislabel.

04

Why it matters

If you run social-skills or inclusion groups, start by shaping peer attitudes early. Add brief explanations of why a classmate may flap or shout. Use short, concrete language such as “His ears hurt when the bell rings.” Track whether friendly approaches rise after the lesson. A five-minute story plus a why sentence can cut rejection more than waiting for maturity to fix it.

03Original abstract

The present study examined public perceptions toward children with autism or with attention deficit hyperactivity disorder (ADHD). A convenience sample was used consisting of 30 children (7-12-year-olds) and 30 adults. Participants read a stereotyped scenario featuring either a child with autism, a child with ADHD, or a normal child. Child participants were significantly more likely than adults to (a) express dislike/avoidance toward a child described with either stereotypic autistic or ADHD behaviors, and (b) perceive the child with ADHD as unlike themselves. However, child participants and adults were equally likely to see the autistic child as unlike themselves. Reasons for the different perceptions of children and adults may include differences in perceived threat and in categorization.
