ABSTRACT
Both historically (Strelau, 1987), and in modern theory (Buss, 1991), temperament has been viewed as that biologically based domain of personality that appears early in life and is stable across time. If temperament traits are the earliest manifestation of later personality characteristics we should expect to find specific linkages between early temperament and later personality (Buss & Plomin, 1984). The hypothesized linkage between temperament and personality is thought to be direct and biologically driven; specifically, it is assumed that common genetic structures drive physiology, neurology, and hormones, which in turn govern the expression of both personality and temperament (Eysenck, 1991; Netter, 1991; also see introduction to this section).
