Bimodal Virtual Reality Stroop for Assessing Distractor Inhibition in Autism Spectrum Disorders.

Parsons et al. (2016) · Journal of autism and developmental disorders 2016
★ The Verdict

VR Stroop uncovers distractor inhibition problems in autistic adults that paper tests miss.

✓ Read this if BCBAs who assess high-functioning adults with autism for college, employment, or independent living.

01Research in Context

01

What this study did

The team built a 3-D Stroop task inside a VR headset.

Adults with autism and typical adults wore the headset and named the color of words that popped up in front of them.

Distractors also appeared in 3-D space. The researchers timed how fast each group ignored those distractors.

02

What they found

On paper Stroop and flat-screen Stroop, both groups scored the same.

Inside VR, the autism group was much slower and made more errors when distractors showed up.

The VR version caught a problem that old tests missed.

03

How this fits with other research

Dall et al. (1997) and Cramm et al. (2009) saw no inhibition gap in autistic kids using stop-signal or social Stroop tasks.

Spriggs et al. (2016) now shows the gap appears in autistic adults once the task is immersive.

The contradiction is only on the surface: earlier work used kids and 2-D tasks; VR adds depth, motion, and real-world noise.

Fitzgerald et al. (2015) found different brain wiring during attention tasks even when behavior looked normal, matching the idea that standard tests can hide real-world struggles.

04

Why it matters

If you assess adults with autism for jobs or driving, a paper Stroop may say "inhibition intact" while VR reveals trouble filtering real-life clutter.

Adding a quick VR Stroop to your test battery can flag clients who need extra distractor-training or workplace accommodations.

03Original abstract

Executive functioning deficits found in college students with ASD may have debilitating effects on their everyday activities. Although laboratory studies tend to report unimpaired inhibition in autism, studies of resistance to distractor inhibition reveal difficulties. In two studies, we compared a Virtual Classroom task with paper-and-pencil and computerized Stroop modalities in typically developing individuals and individuals with ASD. While significant differences were not observed between ASD and neurotypical groups on the paper-and-pencil and computerized task, individuals with ASD performed significantly worse on the virtual task with distractors. Findings suggest the potential of the Virtual Classroom Bimodal Stroop task to distinguish between prepotent response inhibition (non-distraction condition) and resistance to distractor inhibition (distraction condition) in adults with high functioning autism.
