When presented in an introductory course such as TA 101, the ego states seem simple and easy to understand and apply. And that, in fact, is their reality at a first level. The set of thoughts, feelings and behaviors that characterizes each ego state is, by design, easy to identify. The theory was deliberately written so that even a child could understand it. However, we must stress that there is enormous complexity behind that simplification, which points to a very beautiful sophistication in the theory as a whole.

In this article, we propose to present the ego states according to the classic base created by Eric Berne. Although this base has been refined over the years, this starting point is important so we can understand that the foundations of this theory are solid enough to have lasted to this day. As the book What Do You Say After You Say Hello? points out, to appreciate what follows in transactional analysis (TA) one must first understand its principles, with structural analysis, the study of the ego states, as the indispensable first step.

The personality theory of TA rests on the premise that every human being has three types of ego states, defined as “coherent systems of thought and feeling manifested by corresponding patterns of behavior” (our translation). They are psychological realities. The diagram of any human being’s complete personality is therefore represented by three circles housing the Parent, the Adult and the Child. Let us hold to TA’s rigorous nomenclature: ego states are always capitalized (Parent, Adult, Child), while lowercase words (parent, adult, child) refer to real people.

The first type, the Parent ego state (P), is the one derived from our parental figures. In this state, we feel, act, speak and react as one of our parents did when we were small. It is an active state, for example, in raising our own children. Even when we are not actively externalizing the Parent, its behavior influences us in the form of a parental influence, which performs the functions of a conscience. A closer analysis reveals that, functionally, the Parent shows up in two main ways: as the Critical Parent (also called Controlling or Structuring Parent), which sets limits and judgments, and as the Nurturing Parent (also called Protective or Natural Parent), which offers care, permission and safety.

The second is the Adult ego state (A). In it, the person analyzes their environment objectively, calculating possibilities and probabilities from past experience. The Adult works like a computer, processing data from present reality, from the Parent and from the Child, and makes logical, rational decisions. It is guided not by emotion or archaic precepts but by objective evaluation of the here and now.

Finally, there is the Child ego state (C), which represents a little boy or girl who feels, thinks, acts, speaks and reacts in a way similar to how we did as children, usually between ages two and five. In What Do You Say After You Say Hello?, Berne warns that it is important for individuals to understand their Child, not only because it will accompany them throughout life but because it is “the most valuable part of their personality” (our translation). It is the center of spontaneity, creativity, intuition and joy.

At this point, the theory imposes conceptual rigor on us: it is imperative to avoid Parental terms when describing the Child ego state. Words such as childish or immature are judgments of the Parent. The correct description is child-like, which denotes a quality, not a flaw. Functionally, the Child also subdivides: the Adapted Child is the one that follows parental directives to adjust to the world, while the Natural Child is autonomous, spontaneous and free. A variation of the Adapted Child is the Rebellious Child, which systematically opposes parental directives.

The apparent simplicity of this three-circle model, however, hides deeper layers. So-called second-order analysis does not produce new ego states but reveals subdivisions within the basic states. A careful study, as Berne points out, shows that the Parent ego state has two main components: one from the real father and one from the real mother. Even more fascinating is the discovery that the Child ego state itself, at the time of its fixation, already contained within it the rudimentary components of a Parent, an Adult and a Child (the so-called Little Professor). This shows the recursiveness and elegance of a theory that, in its simplicity, manages to map the complexity of personality formation.

We return, then, to the initial paradox. The ego states are, in fact, an accessible model, designed to be a practical, easily applied tool. Yet that accessibility does not diminish their depth. It is, on the contrary, the result of a sophisticated abstraction that condenses years of clinical observation into a functional diagram. Understanding this structure is not an end in itself but the foundation on which the whole edifice of transactional analysis is built. It is the map that lets us navigate transactions, identify psychological games and, finally, analyze and redecide the scripts that govern our lives. The classic base, with its solidity and rigor, remains the indispensable starting point for any journey toward autonomy.
