Stimming sounds vary widely but often include repetitive noises like humming, grunting, squealing, clicking tongues, or throat clearing, along with repeating words, song lyrics, or movie lines (echolalia), all used for self-regulation by people with autism or ADHD to manage sensory input or emotions. These vocalizations can range from quiet murmurs to loud shrieks, depending on the individual and situation.
Stimming (self-stimulatory behaviour) is something that autistic people do, to channel and manage excess energy and to self soothe. It can include things like body movements, making vocal noises or engaging in other stimulation of the senses.
Vocal stimming includes sounds created with one's own voice or throat, such as repeated throat clearing, coughing, repeating a word, or humming. Tactile stimming encompasses touch-based actions, such as rubbing or scratching the skin, opening and closing fists, tapping fingers on surfaces, or flapping hands and arms.
Auditory stimming involves repetitive engagement with sounds or noises. This can include tapping, humming, or even listening to sounds repeatedly.
Perhaps they vocalize and make the same sound or sound patterns over and over again. These behaviors have a name: stimming. The term stimming is shorthand for self-stimulatory behavior. Every person “stims” in some way.
One common misconception is that stimming is solely associated with autism. However, stimming can occur in individuals without autism as well. It is a natural expression of self-regulation and can serve various purposes, such as managing emotions, releasing energy, or promoting concentration.
Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
The ADHD "2-Minute Rule" suggests doing any task taking under two minutes immediately to build momentum, but it often backfires by derailing focus due to weak working memory, time blindness, and transition difficulties in people with ADHD. A better approach is to write down these quick tasks on a separate "catch-all" list instead of interrupting your main work, then schedule specific times to review and tackle them, or use a slightly longer timeframe like a 5-minute rule to prevent getting lost down "rabbit holes".
In autism, self-stimulating behavior includes activities like hand-flapping, finger-flicking, rocking, jumping, and head-banging, among others. On the other hand, people with ADHD may manifest stimming behaviors such as humming, pacing, and teeth grinding to improve focus, self-soothe, or channel energy.
Five key signs of autism spectrum disorder (ASD) involve challenges with social interaction (like difficulty with eye contact or small talk), repetitive behaviors (such as hand-flapping or lining up toys), intense focus on specific interests, sensory sensitivities (to sounds, lights), and strict adherence to routines, often leading to distress when things change. These signs appear differently in children and adults, but generally center around communication, behavior, and sensory processing.
Hidden stimming refers to regulatory behaviours that fly under the radar, these are often subtle, socially acceptable, or deliberately concealed. These are the stims many children use when they don't feel safe to be visibly autistic.
The "6-second rule" for autism is a communication strategy where a speaker pauses for about six seconds after asking a question or giving information, giving the autistic person extra time to process it without feeling rushed, which helps reduce anxiety and allows for a more thoughtful response, reducing frustration for both parties. Instead of repeating or rephrasing, which can be confusing, you wait, and if needed, repeat the exact same words after the pause.
When this occurs, you may observe an autistic girl:
Stimming, which is a nickname for “self-stimulatory behavior” is a repetitive behavior such as head banging, hand flapping, rocking, or making noises or sounds that helps a child with Autism Spectrum Disorder (ASD) to self-soothe.
Palilalia, the delayed repetition of words or phrases, occurs frequently among individuals with autism and developmental disabilities.
Chinning is a form of repetitive self-stimulatory behavior (stimming) that you may notice in children or adults with autism. It involves pressing, rubbing, or holding the chin against objects, surfaces, or even hands to gain sensory input or comfort.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
Stimming behaviors often begin by age 3 and frequently occur when a child is engrossed in an activity or is excited, stressed or bored.
People with ADHD may also be shaking or experience ADHD chills, where they seem to shiver from hyperactivity. Substance use and abuse: A 2015 study indicates that individuals with ADHD have an increased risk of developing a substance use disorder (SUD).
The 5 C's of ADHD, developed by psychologist Dr. Sharon Saline, is a framework for parents and individuals to manage ADHD challenges, focusing on Self-Control, Compassion, Collaboration, Consistency, and Celebration. This approach builds skills for better emotional regulation (Self-Control), empathy (Compassion), working together (Collaboration), establishing routines (Consistency), and recognizing progress (Celebration) to foster a supportive environment and reduce stress.
Unlike traditional ADHD, which is characterized by visibly disruptive behaviors and severe impairments, high-functioning ADHD allows individuals to maintain a semblance of control in daily life. However, this comes at a cost.
The one-touch rule
Teach your child to only pick up each item one time and put it away immediately. It could take some time to get used to, but once they do, this is a simple habit to keep things neat. For example, coloring books go onto their bookshelf, dirty socks go into the hamper, and so on.
While the exact reasons are not yet clear, changes in how the disorder is defined, increases in screening, and more awareness certainly contribute to this increase. If you have any concerns about your child's development, speak to a healthcare professional about diagnostic tests.
Understanding the 6 stages of an autism meltdown can help parents, caregivers, and educators respond with empathy and support.
Additionally, inherited genetic variations contribute greatly. Research shows that both mothers and fathers can carry autism-related gene variants. Some of these are common variants that increase the risk of autism, while others are rare mutations causing more severe effects.
