Thought-bubbles help children with autism acquire an alternative to a theory of mind.

The team worked with three verbal boys with autism. Ages were six, seven, and nine.

Kids first failed false-belief tests. They could not say what another person might think.

Therapists drew cartoon thought-bubbles above stick figures. Kids practiced putting pictures or words inside the bubbles. After ten daily lessons, testers asked the same false-belief questions again.

All three boys passed false-belief tasks after training. Scores jumped from zero to nearly perfect.

Parents also saw change. Kids talked more about feelings and used phrases like "he thinks."

Ahlborn et al. (2008) later ran a bigger Social Thinking class. They also saw large social gains, but they used many lessons, not just bubbles. The 2002 study shows you can start smaller.

Ibrahim et al. (2021) gave social-cognitive groups to older kids while scanning their brains. They found the same social gains plus brain change. Thought-bubble work planted the seed; Karim extended it to eight- to eleven-year-olds and added imaging.

McMillan et al. (1999) warned that autism involves both people and object problems. Thought-bubble training only targets people skills, so pair it with object-use tasks for a fuller program.

You can add thought-bubbles to any table-top lesson. Draw a quick bubble above a picture and ask, "What is he thinking?" Start with one character, then add more. After a few trials, fade the drawing and just point to an empty space. Kids learn to imagine invisible thoughts without extra tools. It takes minutes, costs nothing, and builds theory-of-mind step by step.
