Definition of stimming

: a self-stimulatory behavior that is marked by a repetitive action or movement of the body (such as repeatedly tapping on objects or the ears, snapping the fingers, blinking the eyes, rocking from side to side, or grunting) and is typically associated with certain conditions (such as autism spectrum disorder) Stimming is seen by many therapists as a protective response to less predictable environmental stimuli that some can be overly sensitive to.— Kayla Jane Jeffers When a person with autism engages in self-stimulatory behaviors such as rocking, pacing, aligning or spinning objects, or hand-flapping, people around him may be confused, offended, or even frightened. Also known as "stimming," these behaviors are often characterized by rigid, repetitive movements and vocal sounds.— Teka J. Harris Subtler forms of stimming such as tapping a pencil, biting one's nails or twirling one's hair are common in most people's behavior patterns.— Megan Sheet
