The global structure in terms of "Parent, Adult and Child" can be in turn split into more precise components...
To put it simply, the "Child" dimension (or state) can be broken down into the Spontaneous Child (emotions and feelings), the Spontaneous or Free Child (creativity and intuition) and the Adapted Child (ways of acting or reacting, or "programs")
Similarly, the "Parent" dimension can be broken down into the Normative Parent (rules and norms) and the Nurturing Parent (relating to others).
In terms of its evolution, your personality is created step by step. At the very beginning, the child essentially feels stimuli (the "Spontaneous Child"). He imagines solutions (the "Imaginative Child"), and he then stores these simple ways of functioning ("Adapted Child") developed by himself or dictated to him through his environment and education. The Child state matures from one's birth to around 6 years of age.
The child will then learn, develop and slowly strengthen his rules of behavior ("Normative Parent") and his rules relating to people ("Nurturing Parent"). This entire values system depends on his parents, social background, and culture. This Parent state goes from age 2 until age 6. In the meantime, the child develops his ability to observe and analyze facts ("Adult"), or his ability to think on his own. This Adult state is particularly strengthened between the ages of 3 and 12, and may continue to develop later on
