Final answer:
Conscientiousness has all the characteristics that define temperaments, fitting within the Five Factor Model as a personality trait characterized by self-discipline and thoughtfulness, correlated with positive life outcomes.
Step-by-step explanation:
Recent evidence suggests that conscientiousness has all the characteristics Buss and Plomin use to define temperaments. Temperament refers to inborn, genetically based personality differences and characteristic ways of behaving. Conscientiousness fits within the broader Five Factor Model of personality traits and is characterized by competence, self-discipline, thoughtfulness, and achievement-striving. Numerous studies have found a positive correlation between conscientiousness and various life outcomes, including academic success. Reactivity and self-regulation are two dimensions of our temperament and conscientiousness plays a role in our ability to regulate and control responses to environmental stimuli.
