Test Description

The questionnaire consists of 220 statements, with which the user can either agree or not. Each statement relates to one of 18 scales, the combination of which will form the result.

The scales in the test are three values: deficit, constructive and destructive for each of the 6 functions being examined.

Ammon believed that the leading role in the formation of the structure of the personality is played by various relationships, through which certain values of a particular function are formed. Therefore, the statements that are presented in the test are examples of different situations involving interpersonal interaction.

Characteristics of the functions that form the personality:

  • Aggression. It implies the active interaction of man with the world around him. The desire of the individual to learn something new, to make various contacts, to achieve goals.
  • Anxiety (or fear). The ability to preserve my self in crisis situations, accumulate experience, change due to external circumstances, evaluate cause-effect relationships.
  • External self-delimitation. The ability to distinguish oneself from the surrounding world, to realize oneself as a separate person, to no one is alike and whole. At the same time, the notion is formed that others are also individuals.
  • Internal self-delineation. Function, in fact, is a reflection of the inner world. With its help emotionality, sensitivity, experiences about the occurred events, logic are realized. That is, a complex-organized personality is formed.
  • Narcissism. The function implies an attitude towards oneself, an understanding of one’s own value, as a result of which relations with the outside world are formed. The function realizes not only a mental attitude towards oneself, but also the realization of one’s own parts of the body, for example, hands or feet.
  • Sexuality. The function determines the manifestation and satisfaction of sexual desire, evaluation of one’s own appearance.

Description of the scales forming the results

In the description of each function, constructive, destructive and deficit values alternate.


  • Active desire to interact with people, achieve something, learn something new. Man is building his own life.
  • Interruption of all contacts, decrease in the importance of other people, vindictiveness, cynicism. Destructive activity is directed at itself and everything around. Poor control of outbreaks of aggression.
  • The activity is completely absent. A person withdraws into himself, stops interaction with the outside world.


  • Adequate response to a critical situation, proper risk and hazard assessment.
  • Constant anxiety, fear of yourself and the world around you. Fear of doing something, because of what the development is delayed.
  • No protective reaction or insignificant. The assessment of danger and risk does not correspond to reality. Also, the ability to perceive anxiety / fear of encirclement is lost.

External distinction

  • Adequate control over relationships with people, keeping distance with them and vice versa, rapprochement, depending on the situation.
  • Isolate yourself from people. Decrease or absence of emotions, perception of feelings and desires of others.
  • Inability to control between themselves and others. Excessive adaptation to the feelings, interests and requirements of people.

Internal distinction

  • Ability to distinguish dreams and fantasies from reality. Differentiation of past and present. Adequate understanding of your feelings, emotions and desires.
  • Lack of dreams and fantasies, blocking access to your own unconscious. Barrier between themselves and their lives.
  • Absence of a distinction between reality, fantasies and dreams. The difficulty of differentiation between the conscious and the unconscious.


  • Positive assessment of one’s own personality, appearance, qualities. Satisfying desires and needs in an adequate degree.
  • Negativism, inability to accept help and criticism, to open up to others. Tenderness and a feeling of misunderstanding by others.
  • Negative attitude towards yourself. Refusal of own needs and desires.


  • Ability to enjoy sex and deliver it. Understanding the partner and an adequate relationship with him.
  • Negative attitude towards sexual relations. Perception of them as burdensome, depriving personal space, and therefore rejection of them.
  • Aversion to sexual relations, lack of desire and desire to have sex. Low assessment of their own sexuality, but also the sexuality of others is also estimated low.

Interpretation of results

After passing the test, a score is calculated for each of the 18 scales, in which only affirmative answers are taken into account. Then, using a special formula, T-scores are calculated, from which the results for each scale are evaluated. If you pass the test online on our site, the T-scores will be calculated automatically.

While interpreting the results, a complex evaluation of the obtained data is of far greater importance than that of each criterion alone. All indicators of the scales in their combination form either a “health factor” or a “pathology factor”.

An example of a complex assessment: in destructive aggression, a person does not necessarily have a deviation, since the combination of the criterion with the constructive scales of other functions indicates that the personality is able to cast off old foundations and keep up with the new trends.

The test is of great importance in the clinical practice of psychotherapists. You cannot diagnose it with your help, but you can make assumptions about the mechanism and causes of the pathology and accordingly assign treatment to them. The Ammon test allows you to decompose the structure of the personality into components and evaluate each individually, discovering in the end where the deviation from the norm is hidden.
