If we look at Dr. Ayres studies on sensory integration and we understand that all of us by virtue of being on the spectrum have some modicum of sensory integration problems, then our answer is evident. Some of us obviously are more integrated in space than others. I bump into walls, trip up stairs, often lose my balance walking down stairs, have no depth perception. All sensory integration issues. Some children have such severe sensory integration issues that they cannot cross midline with their bodies or their brains. My son was so impaired that he could not even cross midline during drawing. Drawing a circle involved starting at the top and middle of a circle and progressing to the bottom and middle of one half and then repeating the process on the other half.
So, as adults, these sensory integration issues, which basically amount to understanding where our bodies fit into space and reality, translate as bumping into walls, tripping over air pockets, etc. I think it makes sense. The more that I know and the more that the missing pieces fit in the more I understand about autism in general.
