The Systematic Tool for Analysing Thinking (STAT) offers such a system. It provides a step-by-step method for forming a hypothesis about a child's behaviour, by laying bare the thinking behind it. It then suggests appropriate ways of responding, in order to try and both explain and eventually remedy the difficult behaviour.
This book will be invaluable for parents and professionals working with children with NLD, Asperger's, HFA, PDD-NOS, and other Neurological Differences.
