The document discusses object theory and describes genograms and family circles. It defines a genogram as a genetic map that visualizes hereditary patterns and psychological factors in relationships. The key components of a genogram are listed as 3 or more generations, all family members, birth/death dates, diseases, living situations, marriages/separations, children ordered left to right, and a key to symbols used. Genograms are useful for fast family evaluation, risk factor comparison, early detection of high-risk patients, and patient education. A family circle shows behavioral relationships from the perspective of a family member by placing relatives in concentric circles around the patient.
