Assessment & Research

Children with autism demonstrate circumscribed attention during passive viewing of complex social and nonsocial picture arrays.

★ The Verdict

A three-minute picture-viewing eye-tracker test gives an instant, objective read on how severe a child's repetitive behaviors are.

✓ Read this if BCBAs doing intake assessments or treatment planning for autistic kids.
✗ Skip if BCBAs working only with verbal adults or non-autistic populations.

01Research in Context

01

What this study did

Researchers watched where the kids with autism and 20 typical kids looked.

They showed big picture grids with people, toys, and random objects.

Kids just sat and looked while a camera tracked their eyes for three minutes.

02

What they found

Autistic kids stared longer at tiny details.

They kept going back to the same spots.

The more they did this, the worse their repetitive behaviors were on standard tests.

03

How this fits with other research

Hsieh et al. (2014) seems to disagree. They found autistic kids looked at faces and objects in picture symbols the same way as typical kids. The difference is the pictures: familiar symbols versus new complex scenes.

Davidovitch et al. (2018) built on this idea. They showed a two-minute social video and found eye-tracking scores matched parent reports. This moves the lab finding toward real clinic use.

Wang et al. (2021) added motion. Only some autistic kids preferred spinning toys over people in videos. This shows the detail focus isn't true for every child.

Why it matters

You can spot repetitive behavior severity in three quiet minutes. No tests, no questions. Just show a picture grid and watch. If a child locks onto tiny spots, plan more breaks and vary materials to cut perseveration.

03Original abstract

Although circumscribed interests are a hallmark characteristic of autism spectrum disorders, providing a means for quantifying their functional impairment has proven difficult. We developed a passive viewing task to measure aspects of visual attention in children with autism spectrum disorders and typically developing controls. Task stimuli included picture arrays that were matched for social and nonsocial content. Nonsocial content was balanced to include items related to circumscribed interests (e.g., trains) as well as more commonplace items (e.g., furniture). Discrete aspects of gaze behavior were quantified using eye-tracking technology. Results indicate that visual attention in the autism group was more circumscribed (as indicated by the exploration of fewer images), more perseverative (as indicated by longer fixation times per image explored), and more detail oriented (as indicated by a greater number of discrete fixations on explored images). This pattern of results was similar for both social and object arrays. Within the autism group, overall severity of repetitive behavior symptoms correlated positively with exploration of object pictures and negatively with perseveration on social pictures. Results suggest that children with autism have a domain-general pattern of atypical visual attention that may represent an exaggeration of a typical attentional process and is related to a tendency to perseverate on images of interest and explore them in a more detail-oriented manner. Discrete measures of visual attention may therefore provide a reasonable means of quantifying aspects of the repetitive behavior phenotype in autism.
