This study aims to assess the effects of the degree of self-centredness/selflessness and age on human values priorities according to Schwartz model. This model displays two main dimensions which oppose on one hand, self-enhancement to self-transcendence and on the other hand, openness to change to conservation. The sample consisted of 307 adults aged 18 to 65 who filled in two questionnaires: the Self-Transcendence Inventory (STI) and the Questionnaire of Values by Portraits (QVP). The results show that the more people were selfless, the more they gave greater importance to self-transcendence and less importance to self-enhancement; and inversely. Moreover, the older the participants were, the more they valorised collective values compared to individual values. Finally, age appeared as a more relevant predictor of values priorities than the degree of self-centredness. Such results could be of first importance in terms of designing moral education strategies.
