Four Primary Temperament Dimensions in the Process of Mate Choice

The purpose of this investigation was to examine the role of temperament in the initial attraction phase of mate choice. Cross-cultural surveys, brain imaging studies, population and molecular genetics, comparative research and twin studies suggest that many traits of temperament are heritable, relatively stable across the life course and linked to specific gene pathways and/or hormone or neurotransmitter systems. A literature review of behavior genetics, and studies of neurotransmitters, hormones, medications, illicit drugs, and gender reassignment indicate that a suite of biobehavioral traits are associated with four broad, interrelated yet different neural systems: 1) the related dopamine and norepinephrine systems; 2) the serotonin system; 3) the testosterone system; 4) and the related estrogen and oxytocin systems. Currently biological data are not sufficient to establish the exact biological bases of these four hypothesized dimensions of temperament. Nevertheless, the currently available literature, the reliability of the FRI-NQ measure, and the ten validity measures suggest that four temperament dimensions are likely to be associated with four interrelated yet specific neurochemical systems.

Four Primary Temperament Dimensions Based on Neurochemistry

We investigated the hypothesis that specific suites of co-varying heritable temperament traits are associated with broad yet specific human neural systems. Personality is composed of two basic types of traits: traits that an individual acquires, dimensions of character; and traits with biological underpinnings, dimensions of temperament (Cloninger 1987). This paper examines only those traits the current literature associates with traits of temperament. Many traits of temperament are heritable, relatively stable across the life course and linked to specific gene pathways and/or hormone or neurotransmitter systems. Read More

Lust, Romance, Attraction, Attachment: Do the side-effects of serotonin-enhancing antidepressants jeopardize romantic love, marriage and fertility?

Fisher, H and JA Thomson Jr. (2007)Evolutionary Cognitive Neuroscience. SM Platek, JP Keenan and TK Shakelford (Eds.). Cambridge, MA: MIT Press. Pp. 245-283. Today, millions of people of reproductive age take selective serotonin reuptake inhibitors (SSRIs) and other serotonin-enhancing antidepressants. Approximately 80% of these drugs are prescribed by nonpsychiatric physicians, including internists, general practitioners, pediatricians, […]Read More

Fisher, H, A Aron and LL Brown (2006)“The Neurobiology of Social Recognition, Attraction and Bonding,” Keith Kendrick (Ed), Philosophical Transactions of the Royal Society: Biological Sciences. 361:2173-2186 Mammals and birds regularly express mate preferences and make mate choices. Data on mate choice among mammals suggest that this behavioural ‘attraction system’ is associated with dopaminergic reward […]Read More
