Psychological indicators for high giftedness are, among others, the quickness of thought and understanding and the great sensitivity since the first years of life (
15-
19). These children may react impatiently to other persons who need longer explanations and may be rejected by others. Whilst most of them develop quite positively (
20-
22) and show their intellectual creativity in many realms, some of them are confronted with various psychological problems (
23-
28). If a highly gifted adolescent fails at school, a thorough psychological assessment is necessary to uncover the origin of his difficulties. A retrospective evaluation of ten years, performed in the psychology service of a secondary school, shows that with a total group of 185 highly gifted underachievers, there has been a diagnosis of borderline functioning for 20% of them, depressive reactions to recent events (for instance emigration, death of a beloved person, or a serious somatic disease) for 35%, and minor problems attributed to the neurotic level or linked to the current identity quest for the rest 45% (
5).
The inhibition we encounter among these students meets the criteria of Marcelli & Braconnier (
29) that distinguish three realms covered by the inhibition:
It is important to stress that the intellectual inhibition impedes exclusively the school results but not the results in the intelligence test. The students in our experimental group had an I.Q. of minimum 128, and yet their intelligence was judged mediocre by their teachers, their parents and often by themselves as well. We should emphasize that, according to the European standards, an I.Q. of 128 is the conventionally accepted inferior limit for the definition of highly gifted pupils.
