Parenting Nonverbal Autism And SPD

What You'll Learn

This chapter introduces the core features of nonverbal autism and sensory processing disorder (SPD) and shows how they often appear together in children and young people. You will learn clear, everyday definitions of each condition, typical behaviors to watch for, and why understanding both together matters for therapy, schooling, and daily life. Knowing these basics helps you interpret behaviors without blame and choose practical supports that fit your child's needs.

We connect this material to later chapters on communication strategies, sensory diets, and school planning: once you can recognize the signs and how they overlap, you’ll be ready to choose communication tools, set up sensory supports at home, and talk with therapists using shared language.

Learning Objectives:

• Identify three key characteristics of nonverbal autism and three common sensory differences in SPD.
• Describe one way autism-related communication differences and sensory processing challenges can interact.
• Use observation to note at least two context-specific behaviors to share with professionals.

How It Works

term - nonverbal autism: when a child has autism and uses little or no spoken language to communicate. Nonverbal does not mean non-communicative; many children use gestures, eye gaze, AAC devices (like a simple picture board or a tablet app such as Proloquo2Go), or behavior to express needs, feelings, and choices.

term - sensory processing disorder (SPD): when the brain has difficulty organizing sensory input (sight, sound, touch, movement, smell, taste, body position). This can make ordinary sensations feel overwhelming, dull, or confusing.

Common behaviors - nonverbal autism:

• Limited or no spontaneous words. Example: a 6-year-old who does not use spoken words consistently but signs "more" during snacks.
• Unusual eye contact or gaze patterns. Example: looking at an adult's hand rather than face when asking for help.
• Repetitive actions or intense interests. Example: lining up toy trains for long periods.

Common behaviors - SPD:

• Over-responsiveness (hyper): covering ears at moderate noise levels; refusing certain fabric textures.
• Under-responsiveness (hypo): not noticing when name is called; high pain tolerance.
• Seeking sensory input: constant movement, chewing on clothing, or heavy pressure.

How they intersect

1) Sequence: Sensory overwhelm can reduce a child’s ability to use whatever communication they have. If a child with SPD is exposed to loud classroom noise, their breathing may quicken, they may rock to self-soothe, and speech attempts or AAC use can drop.

2) Example interaction: A child who is nonverbal and sensitive to touch may avoid hand-over-hand signing support, which caregivers might misread as refusal. Instead, using a visual first (a picture card) and gradual touch with calming pressure can help.

3) Practical point: Assess both conditions together. When you note a behavior-like sudden aggression or withdrawal-ask whether it followed a sensory event (a bright light, scratchy shirt) or an unmet communication need.

Concrete tools and terms you may see in reports

• AAC (Augmentative and Alternative Communication): tools from picture cards to speech-generating devices.
• Sensory diet: a planned set of activities (e.g., 10 minutes of trampoline jumping mid-morning) to regulate sensory systems.
• OT (Occupational Therapist): professional often assessing SPD and recommending sensory supports.

Worked Example

Scenario: Maya, age 8, is nonverbal and in a mainstream classroom. Her teacher reports frequent outbursts during transitions. You want to figure out whether these outbursts are sensory, communicative, or both.

1. Observe and record for 7 school days: note time of day, what happened right before each outburst, sensory triggers (noise level, lights, physical contact), and Maya’s available communication attempts. (Example log entry: Day 1, 9:10am, cue: sudden fire drill, noise spike from 50 dB to 95 dB, Maya covered ears and then threw chair.)

2. Count patterns: you find 5 outbursts in 7 days; 4 happen during loud, sudden noises (recess bell, fire drill) and 1 happens when a classmate took Maya’s tablet. This suggests 80% sensory-triggered, 20% communicative need.

3. Trial targeted supports for 2 weeks: give Maya noise-reducing headphones during noisy times and a visible transition schedule (picture sequence) for moving locations; teach a single-button switch that says “help” next to her tablet for communication when frustrated.

4. Collect outcome data: after 2 weeks, outbursts drop from 5 in 7 days to 1 in 7 days. The remaining outburst occurred when the tablet was taken and no one offered the "help" switch.

Final result: The primary cause was sensory (loud noises) with a secondary communication need; targeted sensory supports plus a simple AAC reduced outbursts by 80%.
