Implicit and explicit understanding of ambiguous figures by adolescents with autism spectrum disorder.

Matson et al. (2011) asked 24 teens with ASD and 24 typical teens to copy an ambiguous picture. The picture could be seen as either a rabbit or a duck. First the teen drew what they saw. Then the experimenter showed the other view. Finally the teen drew the picture again.

The team wanted to know if seeing the second view changed the next drawing. They also checked if the teens added extra details that showed they now held both views in mind.

Typical teens changed their drawing after the reversal. They added parts that matched the new view. ASD teens kept drawing the same first picture. Their second drawing looked almost identical to the first.

Only two ASD teens showed any hint of the new view in the second drawing. The rest acted as if they had never seen the switch.

Stamoulis et al. (2015) ran the same rabbit-duck task with college students who reported high autistic traits. These adults also missed the reversal, showing the pattern extends into the general population.

McGonigle et al. (2014) found that most high-functioning youth with ASD slow down on timed visual tasks. Together the studies suggest the issue is not poor vision, but less automatic use of new visual context.

Payne et al. (2020) showed ASD teens are worse at reading negative faces even when basic face perception is equal. Both lines of work point to one theme: teens with ASD often ignore contextual cues that typical brains use right away.

Do not assume a client will pick up the "other side" of a picture, a facial cue, or a hidden rule just because you showed it. State the second view out loud. Use direct prompts like, "Now draw the duck beak." Build check-ins so the learner can practice shifting views with your help. This small step can ease frustration in drawing, social stories, and perspective-taking lessons.
