Dr. Kolevzon dicusses the range of sensory interests and aversions apparent in some children with autism. These sensory issues occur across senses, including sight, sound, touch, taste and smell, and can be simultaneous, such that the same child may seek out some sensations and avoid others. Further, some children demonstrate a reduced sensitivity to pain that may also be an indicator of overarching sensory issues. Notably, though many children with autism display sensory issues, these issues can be apparent in earlier stages of typical development and are common in children with a range of developmental and intellectual impairments.
"Common problems when a child is over sensitive to sensory imput can include crying or avoiding sudden loud sounds in over stimulating environments. Children with autism may also have predictable negative responses to common household sounds..."
