just happened to be:

Just happened to be in a Gestalt therapy group session. The session involved exploration of the Johari Window, a model invented by a couple of psychologists called Jo and Harry* that is used in self-help groups and for corporate purposes to explore the process of self-disclosure. The window divides interpersonal relationships into four quadrants that define whether or not two communicating parties know information about one of them.

The first quadrant is called the "Arena" and is an open area of knowledge that is common to both parties about one of them. Examples could be name, sex and physical characteristics. In the second quadrant, called the "Facade", the first person knows information about her or himself that the second is unaware of. The third quadrant is called the "Blind Spot". Here, the first person is unaware of information that the second knows. The fourth quadrant is called the "Unknown" and represents information that is unknown to both parties.

Like me, most people in the group were interested in having saucy info about their Blind Spot revealed to them. Others in the group gave me details that ranged from verbal abuse to flattery. Such information also depends on the details others are prepared to give (which reveals the extent to which they are willing to disclose information about themselves). A very useful fact I did learn was that the suit and tie that I believed I was wearing was in reality a nun’s habit and wimple.
