Is he visual spatial perhaps? We use a lot of pictures to communicate here. I feel like there are some days I can't get the words out right and other days DS7 is trying to create pictures with words that don't necessarily have a picture. Example: If I need him dressed and out the door, I show him a picture of himself dressed (coat, shoes, etc) first then a picture of him in the vehicle buckled up. That seems to be much more effective than multiple step verbal instructions. HTH
