This is a new unit for Access, and the resources should build as the year passes.  Here are some items I have used on other occasions:

• Classification systems mindmap
• Deviation from norms - a mindmap and a powerpoint which should be taken together.
• Similarly, a mindmap and powerpoint for the medical model which should be taken together.
• Evaluation of the behavioural model - a mindmap
• A powerpoint for abnormal behaviour.  Not mine, I found it on the net.
