Stimming (self-stimulatory behavior) feels like repetitive actions or sounds used to regulate emotions, sensory input, and focus, often calming, exciting, or overwhelming, and can range from hand-flapping, rocking, humming, and repetitive words to finger-flicking, pacing, or watching lights, serving as a coping mechanism for both neurodivergent (like Autistic or ADHD) and neurotypical individuals.
Examples of stimming: Movement/balance: hand flapping, rocking, swinging, jumping, spinning. Sight: watching spinning toys, patterns, glitter, colours or lights (possibly making the light flicker); repeated blinking.
Examples of stimming behaviors
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.
ADHD stimming, short for "self-stimulatory behavior," is a term that encompasses a wide range of repetitive actions and movements. These behaviors, such as nail-biting, leg-bouncing, hair-twirling, and repeating sounds, are observed in some individuals with ADHD.
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.
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.
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.
Stimming behaviors often begin by age 3 and frequently occur when a child is engrossed in an activity or is excited, stressed or bored. An estimated 44% of people with autism report some type of stimming action.
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.
Why do autistic people stim? For autistic people, excess energy can build up for a variety of possible reasons – such as sensory, social, emotional or information overload – or even boredom. Autistic people can also find it hard to move from one activity to another.

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.
People with ASD often have problems with social communication and interaction, and restricted or repetitive behaviors or interests. People with ASD may also have different ways of learning, moving, or paying attention. It is important to note that some people without ASD might also have some of these symptoms.
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.
There is not just one cause of ASD. Many different factors have been identified that may make a child more likely to have ASD, including environmental, biologic, and genetic factors.
While stimming behaviors are often associated with autism, it's important to recognize that they are not exclusive to individuals on the spectrum. Neurotypical individuals, including infants, young children, and adults, may also exhibit stimming behaviors.
Five key signs of autism (ASD) involve difficulties with social communication, repetitive behaviors, intense interests, sensory sensitivities, and strict routines, such as trouble with small talk/eye contact, hand-flapping/lining things up, deep focus on specific topics, sensitivity to sounds/lights, and distress over schedule changes, though these vary widely.
Research tells us that autism tends to run in families, and a meta-analysis of 7 twin studies claim that 60 to 90% of the risk of autism comes from your genome. If you have a child with autism, you are more likely to have another autistic child. Your other family members are also more likely to have a child with ASD.
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.
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.
Individuals with HFA typically have normal to above-average intelligence and may excel in certain areas, such as academics or specific interests. However, they often struggle with social interactions, communication, and understanding social cues, which can impact their daily lives.
The 24-hour rule for ADHD is a self-regulation strategy to combat impulsivity by creating a mandatory waiting period (often a full day) before reacting to emotionally charged situations or making significant decisions, allowing time for reflection and reducing regretful snap judgments, especially for things like impulse purchases or arguments. It's a pause button that gives the brain space to process, move from impulse to intention, and evaluate choices more logically, helping manage ADHD's impact on emotional regulation and decision-making.
The DSM-5 introduced three ASD levels of severity: level 1 (“requiring support”), level 2 (“requiring substantial support”), and level 3 (“requiring very substantial support”).
They might be living with Silent ADHD, also known as high-functioning ADHD —a condition that hides behind ambition, productivity, and achievement. These individuals seem perfectly organized on the outside but often battle scattered focus, racing thoughts, and emotional fatigue beneath the surface.
