Somewhere in Boston, a teenager with profound autism is hunting for gems on a tablet screen — and, without saying a word, teaching scientists something new about how their brain works. That's the quiet revolution happening inside a new video game called Geode, built by researchers at Boston University to finally give people across the entire autism spectrum a voice in science.
For years, the doors to autism research have been half-shut. Scientists knew that people on the spectrum often see the world at a different angle — spotting details others miss, attuned to patterns more than faces, feeling sensations more sharply or more faintly. But the precise brain machinery behind these differences stayed murky. One big reason, says BU researcher Benjamin Scott: studies usually left out people with more severe symptoms, especially those who are nonverbal. The result was a picture of autism painted mostly by people who could easily complete research tasks.
Geode changes that. The game is a simple treasure hunt — players pick a character, follow a map, and grab as many jewels as they can. Meanwhile, flashes sparkle at the edges of the screen; if one side shimmers more, it's hiding gems. While players build their horde, researchers silently track how well they notice these flashes, which vary in number, duration, and timing. "We can collect some very detailed information about how you're making decisions, perceiving the world, and learning to play the game," Scott says. There are no instructions at all — players just jump in and figure it out, which is exactly what lets children with severe communication challenges take part.
During the trial, the team had more than 300 adolescents, ages 11 to 17, play the game. Just over 200 had autism, covering the full range of the spectrum, and the rest were neurotypical siblings. This mattered because autism is far from rare — about 1 in 31 children in the United States have it, according to the nonprofit Autism Speaks. Scientists previously relied on family members' subjective reports for the most affected kids; now the patients themselves could respond, in their own way. "We found we can get these kids to engage and tell us, in their own language, how they're perceiving the world," Scott says.
The study, published in Science Advances and co-authored with experts Helen Tager-Flusberg and Joseph McGuire, pointed to a possible cause of some perceptual struggles: "noisy evidence integration," or how the brain handles a flood of sensory information. The game also worked entirely remotely, drawing in autistic people with varied backgrounds from across the United States. For families who've long watched their children get shut out of studies, that's a door finally opening. The hope is that Geode sparks fresh insights into the autistic brain and helps refine how new therapies are developed and tested — one sparkling treasure map at a time.
