Instructions to attend to an observed action increase imitation in autistic adults.

Gowen et al. (2020) · Autism : the international journal of research and practice 2020
★ The Verdict

A one-sentence ‘watch closely’ erases the imitation gap between autistic and non-autistic adults.

✓ Read this if BCBAs running adult social-skills or vocational programs who rely on imitation.
✗ Skip if Clinicians working solely with toddlers or with non-imitative goals.

01Research in Context

01

What this study did

Gowen et al. (2020) asked autistic and non-autistic adults to copy a simple hand action. Half the group heard the usual ‘do as I do.’ The other half first heard ‘watch closely.’ Then the researchers scored how closely each person matched the model.

The study used a quasi-experimental design in a quiet lab room. Participants saw the action once and then repeated it right away.

02

What they found

Without the extra cue, autistic adults copied the action less accurately than their peers. After the words ‘watch closely,’ their scores jumped to the same level as the non-autistic group.

The single sentence was enough to erase the group difference.

03

How this fits with other research

Espanola Aguirre et al. (2019) showed that both autistic and typical learners master object actions first, then body, then vocal, then facial. Emma’s team built on that sequence by adding a quick attention prompt at the start.

Izadi-Najafabadi et al. (2015) found that explicit verbal instructions hurt motor learning in autistic children. That sounds like the opposite of Emma’s result. The gap is age and task: Sara’s kids had to talk themselves through a brand-new sequence, while Emma’s adults only had to notice what they saw. Less talk, better outcome.

Sharp et al. (2010) and Geurts et al. (2008) both report that autistic people move like controls when cues are clear. Emma adds the practical cue: a plain ‘watch closely’ is all the clarity needed.

04

Why it matters

You can fold this prompt into any imitation program. Before you model a life skill—tying shoes, signing a receipt, loading the dishwasher—pause and say ‘watch closely.’ It costs one second and levels the playing field for adult learners. No extra visuals, no lengthy rules, just the cue. Try it during vocational or social-skills sessions this week and see if the copy-cat step gets cleaner.

03Original abstract

This study investigated whether reduced visual attention to an observed action might account for altered imitation in autistic adults. A total of 22 autistic and 22 non-autistic adults observed and then imitated videos of a hand producing sequences of movements that differed in vertical elevation while their hand and eye movements were recorded. Participants first performed a block of imitation trials with general instructions to imitate the action. They then performed a second block with explicit instructions to attend closely to the characteristics of the movement. Imitation was quantified according to how much participants modulated their movement between the different heights of the observed movements. In the general instruction condition, the autistic group modulated their movements significantly less compared to the non-autistic group. However, following instructions to attend to the movement, the autistic group showed equivalent imitation modulation to the non-autistic group. Eye movement recording showed that the autistic group spent significantly less time looking at the hand movement for both instruction conditions. These findings show that visual attention contributes to altered voluntary imitation in autistic individuals and have implications for therapies involving imitation as well as for autistic people's ability to understand the actions of others.
