🧠 Smart Doesn’t Always Sound Like Speech 🔬Evidence-informed
Many nonspeaking autistic kids think and learn deeply. When we use fair tools and give them ways to communicate (signs, pictures, or devices), their abilities show.
- Nonverbal ≠ not intelligent. Some children score much higher on nonverbal tests (like Raven’s) than on speech-heavy tests.
- Use fair assessments. Try nonverbal IQ tools (Raven’s, Leiter-R) and dynamic assessment—then re-check as skills grow.
- Communication unlocks participation. AAC—manual signs (e.g., Lámh/Makaton), picture exchange, or speech-generating devices—supports real-world inclusion. Good news!

- Autistic intelligence on nonverbal tests: Dawson, Soulières, Gernsbacher, & Mottron (2007). Children with autism scored ~30 percentile points higher on Raven’s vs. Wechsler in the same sample. PubMed | Open access
- Assessing minimally verbal students: Tager-Flusberg & Kasari (2013) review nonverbal/dynamic methods and AAC options for school-aged children with little speech. Open access
- AAC is standard care: ASHA Practice Portal (AAC) describes manual signs, pictures, and devices; recommends multimodal access. ASHA
- PECS meta-analyses: Flippin et al. (2010); Ganz et al. (2012) report improvements in functional communication (speech gains vary by study). Flippin 2010 • Ganz 2012
- Lámh in Irish schools: Frizelle et al. (2022) define a core school key-word signing vocabulary to support inclusion. Journal page • PDF
Important caution: Facilitated Communication (FC/RPM/S2C) is not evidence-based and risks facilitator authorship; choose independent AAC instead. See ASHA statement. Link
How to use this: Pair every sign or picture with spoken words. Start with key phrases (help, break, yes/no, more, stop, happy/sad). Revisit the plan as the child grows.
🗣️ What is AAC? 🎨Pastel • Kid-friendly
AAC = Augmentative & Alternative Communication.
Augmentative adds to speech; Alternative replaces speech when talking isn’t possible or reliable. AAC helps children
understand and express messages using signs, pictures, or devices.
🌈 What it includes
- No-tech: gestures, manual signs (Lámh/Makaton), pointing
- Low-tech: picture cards, PECS, communication books/boards
- High-tech: tablet apps & speech-generating devices (voice output)
🌱 Why we use it
- Reduces frustration; builds real choices & agency
- Supports understanding with visuals + spoken words
- Opens social participation at home & school Good news!
▸ Common examples (tap to expand)
- Key-word signing (e.g., help, break, more, stop, happy)
- PECS: exchanging a picture to ask for something
- Symbol boards/books (core words + fringe words)
- Apps/devices that speak selected symbols or typed text
▸ Myths & facts (tap to expand)
- Myth: “AAC stops speech.” → Fact: Research shows AAC often supports or increases speech.
- Myth: “AAC is a last resort.” → Fact: It can be introduced early alongside spoken language.
- Myth: “Only one way works.” → Fact: Many kids thrive with a mix (signs + pictures + device).
Quick start: Teach key words first (help, break, yes/no, more, stop, happy/sad). Pair every sign or picture with speech. Let the child choose the mix that feels right.
👐 Why we use signs & symbols (AAC) 🔬Evidence-based
- AAC is standard care. Tools like manual signs (Lámh/Makaton), picture boards, and speech-generating devices help many autistic kids understand and express themselves.
- AAC does not stop speech. Research and clinical guidance report no evidence that AAC prevents talking; for many children it increases vocalizations. Good news!
- Manual signs can spark speech. Teaching core signs (with good prompting) has increased spoken responses in some nonspeaking children.
- Key-word signing helps daily life. Programs like Makaton and Ireland’s Lámh show gains in basic communication and participation; some children later use more spoken words.
- Pictures & devices work too. Meta-analyses show PECS improves functional, spontaneous communication; head-to-head studies find signs, PECS, and SGDs can all be effective—best choice depends on the child.

How to use this: Teach key words first (help, break, yes/no, more, stop, happy/sad), pair every sign or picture with spoken language, and let children choose the mix that works best. Reassess regularly as skills grow.
Tip: In Ireland, add a “Lámh Mode” in your activity so families can switch to local sign vocabulary.
