The Science Behind Selective Mutism

The Science Behind Selective Mutism — Educational Infographic (Printable, A2)

You will receive the printable unwatermarked version of this infographic

A clear, research-grounded visual explaining selective mutism as an anxiety disorder — situational speech loss, not shyness.

This infographic covers:

• What it is: an anxiety response, context-dependent, not a choice
• What it can look like: speaking at home but not at school, whispers/gestures, freezing, avoiding eye contact
• What's happening in the body: the pathway from social demand → anxiety rises → freeze/threat response → speech shuts down
• What it's not: shyness, stubbornness, defiance, or low intelligence — and what it actually is: real anxiety, often misunderstood, responsive to support
• What actually helps: reduce pressure, accept other communication (AAC, gestures, writing), warm up gradually, prepare and scaffold, work with school, celebrate communication not performance
• Grounded in NHS guidance and peer-reviewed research; estimated prevalence around 1–2% of children

What you get:

• High-resolution PDF, print-ready and scalable up to A2 (420 × 594mm)
