Temperament is generally identified with: a) the compo- Rothbart and Derryberry (1981) defined temperament as nents of personality that are biological in origin (e.g., Buss & constitutionally based individual differences in reactivity and Plomin, 1984); b) traits that are relatively stable, cross self-regulation (influenced over time by heredity, maturation, situationally consistent, and evident throughout the age span and experience). Reactivity refers to the activation of motor, and diverse cultures (Rothbart & Derryberry, 1981); and c) the affective, autonomic, and endocrine systems.
