Although autistics usually appear physically normal and have good muscle control, unusual repetitive motions, known as self-stimulation or "stimming," may set them apart. These behaviors might be extreme and highly apparent or more subtle. Some children and older individuals spend a lot of time repeatedly flapping their arms or wiggling their toes, others suddenly freeze in position.
As children, they might spend hours lining up their cars and trains in a certain way, rather than using them for pretend play. If someone accidentally moves one of these toys, the child may be tremendously upset. Autistic children often need, and demand, absolute consistency in their environment. A slight change in any routine—in mealtimes, dressing, taking a bath, or going to school at a certain time and by the same route—can be extremely disturbing.
Repetitive behavior sometimes takes the form of a persistent, intense preoccupation. For example, the child might be obsessed with learning all about vacuum cleaners, train schedules, or lighthouses. Often they show great interest in numbers, symbols, or science topics.
