Answer:
"Temperament is not changeable."
Step-by-step explanation:
When we speak of temperament, we refer to that innate part of our personality that is determined by our genetic heritage. Therefore, it is considered the biological and instinctive dimension of personality. In fact, temperament is the first personality factor to manifest.
Being of genetic origin and fruit of the hereditary constitution, the temperament can hardly be modified, manipulated or changed by the circumstances. Always, somehow, there will be this tendency; though it is no less true that we can use resources to increase or inhibit its manifestation.
Therefore we can conclude that although temperament is difficult, it is somewhat changeable, therefore, that an easy temperament can serve as a protective factor against psychopathology.
