Preverbal constructs can produce psychosomatic disorders.
Like a muscle, a construction system that is used, is developed. A person chooses for himself that alternative in a dichotomized construct through which he anticpates the greater possibility for extension and definition of his system.

The variation in a person's construction system is limited by the permeability of the constructs within whose ranges of convenience the variants lie.
