There are a host of personality traits linked with four brain systems. The dopamine, testosterone, estrogen, and serotonin systems.
The four traits of temperament are Explorers, Builders, Directors, and Negotiators. Note that any of these can pertain to a man or a woman. Each temperament has its own traits and is driven by a particular neurotransmitter or hormone.
Robina 7 Day Doctors and Acupuncture recommend this video by Dr Helen Fisher on 4 Styles of Personality:
Each person’s personality type is in part determined by his or her dominant brain chemical: a product of the two sex hormones (oestrogen and testosterone) and two neurotransmitters (dopamine and serotonin). The chemical with the highest activity in your brain is the most influential in determining not only your personality, but who you are likely to fall in love with.
Explorers are curious and energetic. They’re driven by dopamine—the pleasure neurotransmitter. It gives us a sense of elation, accomplishment, and reward. Pretty much anything that gives us pleasure from food to alcohol to sex gooses dopamine production. Explorers are thrill seekers who are open-minded, creative, and cerebral. They crave adventure and novelty, and are easily bored. They may be impulsive and lack introspection however, as they are forever outward looking.
Builders are cautious. They’re driven by serotonin which gives us a sense of relaxation, belonging, and comfort. They’re sociable, follow the rules, and are respectful. These folks are meticulous, orderly, methodical, good with numbers, and may be religious. They are creatures of habit and practice self-control. Dr. Fisher calls this type “cautious/social norm compliant.”
Directors are driven by the testosterone system. They are honest, confident, assertive, and analytical. As a result of receiving fetal testosterone, they have a tendency to understand math, music, computers or any “rule-based systems.” They also have higher visual-spatial perception, which may make them good at sports. These are detail-oriented. Directors become experts in a certain field, but may not have too many interests beyond that. They may lack empathy or sensitivity, be less verbally astute, less understanding of others emotions, and give less eye contact. They also may prone to being flooded by their emotions, making them prone to outbursts, particularly of anger.
Negotiators received a hearty helping of prenatal estrogen. Estrogen is closely related to oxytocin, the “calm and cuddle” hormone. This type is trusting, generous, imaginative, social, and open-minded. They’re also very nurturing and empathetic. Negotiators have excellent verbal skills. Dr. Fisher calls them, “prosocial/empathetic.”
