As with many autistics Alex has sensory sensitivity, itself in a couple ways touch and balance. Alex can obsess for hours over videotapes, his favorite being Elmo, he will stop and rewind and play them over and over again always stopping at the same scene. It can occupy him for hours always stopping on the same scene without watching the buttons he's pushing on the VCR. Alex will also use the dialogue on the tapes express things since he is a nonverbal communicator.
