Closed system disorder. A child profoundly and repetitively engaged with an object (action-object system) who cannot permit people to become part of his or her action-object systems demonstrates a closed system disorder. We refer to it as a "disorder" because such behavior actively interferes with coping.
There are two types ofclosed system disorder: Type A (involvement with one or two action-object systems) and Type B (involvement with multiple action-object systems).
System-forming disorder. A child who has great difficulty forming systems because he or she is constantly driven by various stimuli in the environment, or because poor coordination interferes with the ability to engage with objects or events, demonstrates a system-forming disorder.
There are two types ofsystem-forming disorder: Type A (related to poor coordination) and Type B (stimulus-driven).
