Do Children and Adults with Autism Spectrum Condition Anticipate Others' Actions as Goal-Directed? A Predictive Coding Perspective.

Ganglmayer et al. (2020) showed short videos to people with autism and to typical controls. In each clip a hand reached for one of two objects.

The team tracked where the viewers looked. They wanted to know if autistic viewers could predict the goal of the reach before it ended.

Both groups looked to the correct object ahead of time. The autistic group, however, took longer to shift their eyes.

The delay fits the idea that autistic brains need extra time to apply past knowledge to new actions.

Schuwerk et al. (2016) saw the same slow-down using a similar task. Their paper came first; the new study adds a wider age range and a fresh theory lens.

Zalla et al. (2013) tested toddlers with autism. When hand cues were hidden, the toddlers kept staring at the old spot instead of the new goal. The 2020 paper shows this habit persists into adulthood.

Hou et al. (2024) looked deeper. They found autistic kids could predict simple actions but stumbled when the action meant “giving” versus “taking.” Together the studies say: prediction of motion is intact; grasping the social meaning is the weak spot.

Your client can guess where a hand will land, so do not waste time drilling basic prediction. Instead, slow your teaching pace. Insert two-second pauses after each social cue. Use those pauses to label the goal out loud (“He wants the cup”). The extra processing time lets the autistic brain catch up and link the action to its social purpose.
