How does Temple Grandin use imagery in Emergence: Labeled Autistic?

Grandin uses the repeated imagery of a sliding glass door to illustrate the way she is separated from other people and "normal" sensory experiences such as certain fabrics or even the touch of her own skin. She points out that autistics need touch just as much as other people but cannot receive it. Temple quotes scientists that say that any tactile stimulation is better than none, that lacking touch can cause "hyperactivity, autistic behavior, violence and aggression."
