the underlying biological mechanisms behind Helen Fisher's 'Four primary temperament dimensions in the initial phase of mate choice'.

Abstract

This thesis seeks to provide empirical support for the biological systems behind Fisher’s four primary temperament dimensions. Fisher’s theory consists of two parts, first, the broad interrelated dopamine-, serotonin-, testosterone-, and estrogen systems are responsible for four temperament dimensions in human beings. Second, next to proximity, timing, familiarity, same socio-economic status, ethnic background, level of education and other environmental factors, also these four temperament dimensions play a role the initial phase of mate choice; individuals seek for a mate that has similar dopamine- and serotonin levels but complementary testosterone- and estrogen levels. In this thesis, the underlying biological systems are explained in more depth and the association with personality traits are discussed as well as parallels between Fisher’s theory and different personality theories. Further investigation of the link between personality and mate choice is important because 80% of human population in the world only make that choice once or twice in their lives, as they are monogamous. A better understanding of one’s temperament and that of the partner would facilitate the detection of relationship problems, which could enhance the couple’s happiness.
