Autism / Autism Spectrum Support Group
Autism is classified as a neurodevelopmental disorder which manifests itself in markedly abnormal social interaction, communication ability, patterns of interests, and patterns of behavior. Although the specific etiology of autism is unknown, many researchers suspect that autism results from genetically mediated vulnerabilities to environmental triggers.
That reward theory really is good advice. I practice that on myself, I will only reward myself when I feel that I really deserve it. On a very busy day I will always schedule little rewards in, like getting a drink after I do x amount of work, eating after I do x amount of tasks. I constantly do that and it makes me look forward to simple rewards.
We have got the visual schedule that sambod has mentioned. It's used at school where children go with many types of disabilities and they've found it to be a great help.
