“…Temperament traits (novelty seeking, harm avoidance, reward dependence and persistence) represent basic emotional responses, which are manifested early in life, are stable throughout life and are moderately heritable. Character traits (self-directedness, cooperativeness and self-transcendence) represent concepts about self and personal relations, which are regulated by supervisory cognitive processes that develop throughout life (Cloninger et al, 1994;Cloninger et al, 2005). When compared to healthy individuals, bipolar patients achieve higher scores on novelty seeking (Young et al, 1995;Osher et al, 1999;Evans et al, 2005), harm avoidance (Young et al, 1995;Osher et al, 1996;Engstrom et al, 2004a;Evans et al, 2005) and reward dependence (Osher et al, 1996), and lower scores on persistence (Osher et al, 1996;Osher et al, 1999) and self-directedness (Engstrom et al, 2004a;Evans et al, 2005).…”
