The rubber hand illusion in children with autism spectrum disorders: delayed influence of combined tactile and visual input on proprioception.

The team used the rubber-hand illusion with kids. One group had autism. One group was neurotypical.

They brushed the child’s hidden real hand and the visible fake hand at the same time. They asked, "Does the fake hand feel like yours?" They also rated each child’s empathy level.

Typical kids felt the illusion right away. Kids with autism felt it too, but only after six extra minutes.

Children with lower empathy scores were less likely to ever feel the illusion.

Mul et al. (2018) extends this link. They show that autistic adults who also have alexithymia show weaker body awareness and lower empathy. The pattern starts in childhood and lasts into adulthood.

Schroeder et al. (2014) looks at first-graders with autism. They found the kids had intact emotional empathy but weaker perspective-taking. This supports the idea that you should teach point-of-view skills, not try to "make" them feel.

Trimmer et al. (2017) seems to disagree at first. They found autistic adults had normal body arousal yet reported feeling less emotion. The studies don’t clash; one shows body timing delays, the other shows emotion labeling gaps. Both point to giving extra processing time.

When you run social or sensory lessons, give autistic learners a longer window for the cues to sink in. Pause at least six minutes before checking if they "feel" the activity. Also screen for empathy level; kids with lower empathy may need simpler, slower multisensory steps. Build in tactile prompts they already like, and ask parents about real-life empathy, not just what you see in clinic.
