Referential gaze and word learning in adults with autism.

★ The Verdict

Autistic adults can use eye gaze to learn words if flashy distractors are kept away.

01Research in Context

01

What this study did

Aldaqre et al. (2015) asked adults with autism to learn new words by following another person's eye gaze. The team showed a speaker looking at one of several objects while saying a made-up name.

Some trials added bright, moving distractors to make the task harder. The researchers tracked where the adults looked to see if they could still link the gaze cue to the correct object.

02

What they found

Adults with autism could learn the new words when the scene was simple. Their accuracy dropped when flashy distractors competed for attention.

Neurotypical adults kept learning even with the bright distractors. The gap shows that salience, not the gaze cue itself, trips up autistic learners.

03

How this fits with other research

Rombough et al. (2013) saw a similar dip in autistic children when they had to pick eyes over arrows. Both studies point to trouble selecting social cues under visual clutter, not trouble following gaze itself.

Fletcher-Watson et al. (2008) found autistic adults spotted gaze shifts as fast as peers. Iyad's word-learning task adds a functional layer: the same intact gaze detection can be blocked later by high salience distractors.

Bigham et al. (2013) showed preschoolers with autism could learn words from gaze if their developmental level was high. Iyad extends this upward, showing the skill persists into adulthood but remains fragile when the scene gets busy.

Why it matters

You can teach new vocabulary to autistic adults by looking at the target item, but cut the visual noise first. Turn off spinning toys, cover bright shelves, or use a plain table. One clear gaze plus a quiet background gives your learner the best shot at picking up the new word.

03Original abstract

While typically developing children can use referential gaze to guide their word learning, those with autism spectrum disorder are often described to have problems with that. However, some researchers assume that the ability to follow gaze to select the correct referent can develop in autism later compared to typically developing individuals. To test this assumption, we compared the performance of adults with and without autism on a word learning task while recording their gaze behavior using an eye tracker. Results showed that both groups mostly chose the correct referent, but less so for the autism spectrum disorder group when the distractor's saliency was increased, suggesting that the ability to learn novel words by referring to gaze develops in autism spectrum disorder, but not fully, relative to their typically developing peers.
