Active child vs. Active parent
This scenario is thought to produce Enneagram type 8.
The child and parent experience open conflicts on a regular basis. They both have different agendas and oppose each other, thus giving rise to power struggles and explosive arguments. The Active parent is impatient and intolerant of the child's rebellious nature and tries to impose his will in an authoritarian fashion. The Active child, on the other hand, becomes aggressive, argumentative and persistent in getting his own way. The relationship becomes a sort of battlefield, which is how the child will later perceive the world around him (type 8).
Such a childhood scenario encourages the child to develop a keen eye for spotting other people's weaknesses and a thirst for imposing their will in an overly aggressive fashion. They learn to be assertive, strong and deny their fears and feelings of intimidation. These are the traits they needed to have in order to stand up to their domineering parents and still keep their own Active inborn approach.
Active child vs. Responsive parent
This scenario is thought to produce Enneagram type 7
The demands and concerns of the Active child are usually received with benevolence and a supportive, encouraging attitude. This creates a tolerant environment in which the child can express himself openly and receive attention without much effort from his part. The Active child becomes self-confident, carefree and expects his interactions to be positive and favorable to his needs. The Responsive parent is sympathetic and loving, thus stimulating the child's playful, self-expressive side and giving him a good deal of personal freedom.
This childhood scenario promotes a cheerful, optimistic type who knows how to charm and manipulate others into easily getting his way. Entertaining and expressive, such a child may later expect instant gratification for all his needs and desires and avoid investing time and effort into long-term goals.
