Serious games have been successfully used to treat a variety of conditions and support behaviour change. This presentation explores how these games may help (and have helped!) children with selective mutism and social anxiety develop speech. By integrating behavioural techniques such as shaping, fading, systematic desensitization, and positive reinforcement, serious games can support children to build their communication skills independently while having fun. Learn how gamifying behaviour therapy creates a safe and engaging space for children to find their voice, and at their own pace.
