Character, on the other hand, is defined in terms of individual differences in self-concepts that develop across the lifespan in response to socio-cultural influences. It includes three dimensions: (1) Self Directedness (SD), which is the ability to regulate and adapt behaviour to the demands of a situation in order to achieve personally chosen goals; (2) Cooperativeness (C), which expresses the degree to which a person is generally helpful and agreeable in his/her relations with others; and (4) Self Transcendence (ST), which is associated to the ability to recall the past and imagine the future in developing one's life narrative, as well as to experience an unity with nature and to develop spiritual values.
