What Is Stimming?

Stimming is short for self-stimulation. Stimming is a repetitive body movement, such as hand flapping. Stimming is commonly found in Autism and Sensory Processing Disorder, but also found in other developmental disabilities. This behavior may involve any or all of the senses in various degrees in different individuals.

When children are hypersensitive, or overly sensitive to stimuli they possibly may engage in stimming because they want to reduce stimulation, because they perceive their environments and surroundings  to be too loud, bright or too much to handle. 


When children are hyposensitive, or under-responsive to stimuli they have the opposite effects and stimming may actually increase arousal. You may notice they are engaging in self-stimulatory behaviors that are providing them with sensory excitement. You may notice flapping their arms, spinning, licking and sucking on toys. 

Stimming may become self-injurious behavior such as head banging or biting their hands. Not all self-injurious behaviors are considered stimming. Self-injurious behavior could also be your child trying to tell you that they are frustrated. 

There're a few reasons why individuals may engage in self-stimulatory behavior, and it's not always the same reasons for each person... It may be that the behavior provides sensory reinforcement or sensory stimulation to the individual, or the behavior may be used to regulate sensory input, either increasing stimulation or decreasing sensory overload.

There is visual stimming, olfactory stimming, auditory stimming, oral stimming, vestibular stimming and tactile stimming.
