Therapy
One therapeutic target may be the expansion of the Open (Arena) square at the expense of both the Unknown square and the Blind (Blind Spot) square, resulting in greater knowledge of oneself, while voluntary disclosure of Hidden (Facade) or Blind (Blind Spot) squares may result in greater interpersonal intimacy and friendship. ==See also==
