Understanding Why Autistic People May Reject Social Touch

One of the hardest challenges for families facing autism is the problem of touch. Often, autistic children resist hugging and other types of physical contact, causing distress all around.
Now, a new study offers insight into why some people shrug off physical touches and how families affected by autism may learn to share hugs without overwhelming an autistic child’s senses.
Yale neuroscientists recruited 19 young adults and imaged their brain activity as a researcher lightly brushed them on the forearm with a soft watercolor paintbrush. In some cases, the brushing was quick, and in others slow: prior studies have shown that most people like slow brushing and perceive it as affectionate contact, while the faster version is felt as less pleasant and more tickle-like.
