Children with ASD also act in ways that seem unusual or have interests that aren’t typical, including:
- Repetitive behaviors like hand-flapping, rocking, jumping, or twirling
- Constant moving (pacing) and “hyper” behavior
- Fixations on certain activities or objects
- Specific routines or rituals (and getting upset when a routine is changed, even slightly)
- Extreme sensitivity to touch, light, and sound
- Not taking part in “make-believe” play or imitating others’ behaviors
- Fussy eating habits
- Lack of coordination, clumsiness
- Impulsiveness (acting without thinking)
- Aggressive behavior, both with self and others
- Short attention span
