Alteration of attentional blink in high functioning autism: a pilot study.

Amirault et al. (2009) · Journal of autism and developmental disorders 2009
★ The Verdict

High-functioning autistic people need more time between rapid cues—slow your instruction pace.

✓ Read this if BCBAs who present fast instructions or visual streams in clinic or classroom.
✗ Skip if Practitioners working solely with non-visual or self-paced tasks.

01Research in Context

01

What this study did

Amirault et al. (2009) ran a small lab study with high-functioning autistic adults and matched controls. Everyone watched a rapid stream of letters on a screen and pressed a key when they saw two target letters.

The task is called the attentional blink. If the second target comes too soon after the first, most people miss it. The team asked: do autistic adults need more time between targets?

02

What they found

The autistic group showed a longer attentional blink. They needed more milliseconds to spot the second target.

In plain words, their attention took longer to reset, so rapid instructions or visuals may lose them.

03

How this fits with other research

The 2023 meta-analysis by M et al. pulls 44 studies and finds the same slow-down across many simple reaction tasks. Marion’s blink result now sits inside this bigger picture.

Ganz et al. (2009) ran almost the same blink task in the same year. They added emotional words and still found autistic adults lagging, giving a clean conceptual replication.

McGonigle et al. (2014) later tested youth with a new rapid visual game and again saw two-thirds of the ASD group slow down. The blink finding extends to kids and to different visual setups.

04

Why it matters

If you run discrete-trial training, give instructions, or flash visual cues faster than about one per second, some autistic learners may miss every second one. Insert a brief pause—just a half-second—between critical stimuli. You will raise accuracy without extra prompting.

03Original abstract

Autism is characterized by deficits in attention. However, no study has investigated the dynamics of attentional processes in autistic patients yet. The attentional blink (AB) paradigm provides information about the temporal dynamics of attention in particular about the allocation and the duration of an attentional episode. We compared 11 high functioning autistic patients with 15 control participants on a classical AB task. Autistic patients exhibited a deficit in rapidly allocated attentional resources. Further investigations such as coupling AB evaluation with neuroimaging data and/or increasing the size of groups, would allow for investigating the neurobiological substrates of these AB alterations in autistic patients.
