In this model where a person represents a personification dictates the quality of the relationship that they have with them. Someone that might you might be close too will quite literally be close to you. Someone that you might not keep in touch with or what others might dictate as having a distance relationship will be represented at a great distance from the person representing them.
A person's entire past/current relationship with their family can be mapped out geographically revealing quite a tremendous amount of information regarding the quality of their relationship with their family. This model is amazing simple and yet in depth and would require a great deal more than this single blog post in order to fully give the reader an appreciation for all of the intricacies of Derks work. A person would do well read Derks book Social Panorama and to test out all of the exercises that he outlines on them self and others, I did and I was impressed.
