Behavior and Skill Development

Building Skills and Behaviors at Home with NeuroToggle®

If your child is not speaking or has limited speech

Speech is not just about knowing words. It depends on sensory pathways, processing pathways, motor pathways, breathing, facial movement, and coordination working together.

Build

Target the smaller skills involved in speech, such as joint attention, imitation, facial movements, breath-based activities, gestures, and sound attempts.

Strengthen

Use repeated, targeted learning experiences to reinforce these pathways so the signals involved in speech become more reliable over time.

Time

Support speech during critical and sensitive developmental windows, and use consistent repetition so the circuitry for communication is activated again and again.

Expand

Pair physical speech-related activities with language and interaction so motor, sensory, and language circuits begin working together more flexibly.

In the parent PDF, speech support was approached in sequence: joint attention first, then mirroring, then independent initiation, while pairing movement, facial work, breath-based toys, and language at the same time.

Understanding Autism Traits, Neural Circuits, and Regulation

Why Skills and Behaviors Can Be Hard to Access

Autism is a neurodevelopmental condition, which means autism traits are connected to differences in neural development. Skills and behaviors depend on neural circuits that hold the information needed to perform, execute, and express actions. When those circuits develop differently, a child may have difficulty accessing speech, movement, learning, communication, regulation, or adaptive behaviors consistently.

The behavior is not the starting point. The circuit is. Parents can better understand their child when skills and behaviors are viewed as outputs of sensory, motor, and cognitive neural circuitry rather than as isolated behaviors.
Autism Traits

Autism Traits Are Related to Neural Development

Skills and Behaviors Develop Through Neural Circuits

Skills and behaviors do not appear automatically. They develop through neural circuits that receive information, process information, and coordinate responses. These circuits hold information involved in the performance, execution, and expression of skills and behaviors. Because autism is a neurodevelopmental condition, differences in neural development may influence how skills and behaviors emerge, are accessed, and are regulated over time.

Input

Sensory Circuits

Neural circuits receive information from the body and environment through sensory systems.

Processing

Cognitive Circuits

Neural circuits organize, interpret, store, and connect information used for learning and behavior.

Output

Motor Circuits

Neural circuits coordinate movement, speech, gestures, facial expression, and other behavioral responses.

Autism traits are related to neural development. When sensory, cognitive, or motor circuits develop differently, the skills and behaviors they support may become delayed, inconsistent, difficult to access, or dysregulated.
A child may understand more than they can physically show. Sensory, cognitive, and motor circuits do not always develop or function at the same level. A child may demonstrate strengths in some skills and challenges in others because different circuits can be affected differently. Because sensory, cognitive, and motor pathways do not always develop or function equally, what a child can demonstrate may not always reflect what they know, understand, or are capable of learning.
NeuroToggle®

NeuroToggle® as a System for Building Skills and Behaviors

Target the Circuit Behind the Skill

NeuroToggle® is a neuroplasticity-informed instructional system for targeting the neural circuits involved in skills and behaviors. Instead of waiting for development to happen passively, NeuroToggle® uses structured learning experiences to help build, strengthen, expand, and time the neural circuits involved in a specific skill.

Build

Create the connection for a skill that has not yet developed.

Strengthen

Reinforce the circuit so signals travel more reliably.

Expand

Link circuits together so the skill becomes more flexible.

Time

Improve sequencing so the action becomes smoother and more automatic.

The goal is not to force behavior. The goal is to build access. NeuroToggle® focuses on the neural circuit involved in a skill or behavior, then uses targeted instruction and experience to make that circuit more available, coordinated, and repeatable.
Kitzerow's Theoretical Model

Why Autism Traits and Comorbid Traits May Occur Together

Development and Regulation Compete for Biological Resources

Kitzerow's autism and the comorbidities theoretical model proposes that prolonged biological stress may shift resources toward regulation and survival. When that occurs during development, resources available for typical neural development may be reduced. Within this model, autism traits and comorbid traits emerge together because they are influenced by the same underlying biological priorities.

Development

Timing Matters

Neural circuits develop during important developmental periods. Changes during those periods may influence how communication, movement, learning, and regulation develop over time.

Prioritization

Survival Comes First

When the body is focused on managing stress, inflammation, injury, illness, or other biological demands, resources may be redirected toward regulation and stabilization.

Outcome

Traits Cluster Together

Within this model, autism traits and comorbid traits often appear together because they are influenced by the same underlying regulatory shifts occurring during development.

Development and regulation are interconnected. When the body must repeatedly prioritize regulation, the timing and accessibility of skills supported by neural circuits may be affected. BioToggle® was developed to help explain how these broader regulatory shifts may contribute to autism-associated comorbid traits.

Separating Autism Traits and Comorbid Traits

Within Kitzerow’s autism and the comorbidities theoretical model, autism traits and comorbid traits are separated into different categories. Autism traits are related to the development and function of sensory, cognitive, and motor neural circuits. Comorbid traits are related to how the body responds to activation of regulatory system domains and how those responses epigenetically influence function, development, and cumulative wear and tear over time. Different patterns of domain activation produce different patterns of comorbid traits.

Autism Traits

Neural Development

Autism traits are related to the development and function of sensory, cognitive, and motor neural circuits that support skills, behaviors, communication, movement, learning, regulation, and adaptive functioning.

Comorbid Traits

Regulatory System Domains

Comorbid traits are related to how the body responds to activation of regulatory system domains and how that epigenetically impacts function, development, and wear and tear over time.

Clarity

Match Support to the Mechanism

Separating autism traits from comorbid traits can help families think more clearly about whether a concern may need support for neural development, body-system regulation, or both.

BioToggle® organizes comorbid traits across five regulatory system domains. These domains include the immune system, metabolism, cellular repair, nervous system, and genetic regulation. Their activation influences BioDial activity across the body's temporal system domains, including ultradian, circadian, circannual, developmental, and aging cycles. Different comorbid conditions may involve different domains or overlapping patterns across multiple domains.

Why Parents See So Many Different Autism Theories Online

Many Theories Focus on Different Regulatory Systems

Parents often encounter conflicting explanations about autism, nonverbality, diet, genetics, detoxification, therapy, nutrients, and nervous system regulation. Many of these discussions focus on different systems involved in how the body maintains balance, responds to stress, and supports development.

Immune

Inflammation and Defense

Some approaches focus on immune dysregulation, inflammation, gut health, illness, environmental exposures, and protective stress states.

Metabolism

Energy and Nutrients

Some approaches focus on folate metabolism, B vitamins, mitochondrial function, nutrient absorption, and cellular energy production.

Nervous System

Dysautonomia and Regulation

Some approaches focus on autonomic regulation, fight-or-flight responses, shutdown, digestion, breathing, heart rate, and stress physiology.

Cellular Repair

Repair and Recovery

Some discussions focus on cellular repair, regeneration, and emerging therapies that remain controversial or still developing.

Genetic Regulation

Genetic and Epigenetic Factors

Genetics can influence metabolism, immune function, nervous system activity, development, and how the body responds to stress.

BioToggle®

Body System Regulation

BioToggle® organizes these regulatory systems so families can better understand why comorbid traits may cluster alongside autism.

Nonverbality - An Autism Comorbidity

Understanding Nonverbality and Speech Access

A Missing Piece of the Conversation

Research has long focused on language and cognitive processing in nonverbal autism. Kitzerow's work highlighted an additional question: what happens when a child understands language but cannot consistently access the sensory and motor systems required to physically produce speech? That question led to a broader examination of speech access, pathway delineation, and the need for diagnostic and prognostic protocols for nonverbality.

The same outward presentation does not necessarily reflect the same mechanism. Understanding nonverbality requires looking beyond whether a child speaks and examining the pathways involved in speech access. Different mechanisms may require different supports, accommodations, and expectations. The development of sensory, cognitive, and motor circuits may be dysregulated at different times and to different extents. A child may understand language but struggle to physically produce speech. Another child may speak fluently but have difficulty processing information. Because different parts of the pathway can be affected differently, what a child can demonstrate may not always reflect what they know or understand.

Parent Reminder

Move Slowly, Ask Questions, and Support Access

The Goal Is More Accurate Support

Every autistic child has a different developmental profile. What helps one child may not help another. Parents can start by asking what skill or behavior is difficult to access, what neural circuitry may be involved, whether the child is regulated enough to learn, and whether comorbidities may also need support from qualified professionals.

The goal is not to make autism more complicated. The goal is to make support more accurate by separating skills and behaviors from body-system regulation, then matching support to the child’s actual needs.
Nonverbal Autism

Understanding Nonverbality as an Autism Comorbidity

Nonverbality, the inability to produce speech sounds, is not the absence of understanding. It is a breakdown in the pathways required to produce speech.

Speech-Motor Pathways

Speech is produced through speech-motor pathways.

When a child is nonverbal, the issue is not whether these pathways exist, but which part of the pathway is not functioning as expected.

The challenge is that there is currently no clear protocol to identify which mechanism is affected in each individual nonverbal child.
