Summary
This study tests whether playing action video games can improve reading in children with dyslexia by training their visual attention. About 76 Cantonese-speaking children with dyslexia will be randomly assigned to play either an action game or a non-action game for 12 hours. Researchers will measure changes in visual attention, memory, and reading skills before, during, after training, and at a 6-month follow-up.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- action video game training (Rabbids: Party of Legends)
- What this could lead to
- If it works, this could provide a new, non-reading-based way to help children with dyslexia improve their reading skills by training visual attention.
- What could go wrong
- This is a small, early-stage trial with 76 children, so results may not apply to all. The improvement may be limited or not last long-term.
