Jordy Vacacela wrote a report for their 1st year B course on October 21st, 2015 about personality. The report discusses that personality has two elements - temperament, which has a genetic origin and determines emotional traits, and character, which is determined by the social environment. It also notes that sociable people find socializing rewarding, and responsible people worry about their obligations. Temperament refers to the relatively stable emotional traits influenced by biology that determine behavioral reactions.
