Presents Extraversion-Ambiversion- Introversion  Arlene R. Taylor PhD Brain References

The amount of energy expended in relation to amount of stimulation in the environment It may or may not involve people… 3rd Layer  Arlene R. Taylor PhD Realizations Inc

 Extreme extravert – a special callus allows the brain to function in environments that would overwhelm other brains  Extreme introvert - a special ability shuts out additional input so it can process what has already been absorbed  Ambiversion – does not exhibit the special forms of giftedness A Special Giftedness  Arlene R.

The E:I Continuum  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Ambiverts 70% Introverts 15% You can move along the continuum at will to some degree, but if you spend large amounts of time away from your innate position it will cost you significantly in energy

Generally, who does society reward?

Blood Flow  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Lower blood flow to brain (lower internal stimulation) AmbivertsAmbiverts Introverts 15% Higher blood flow rates to the brain (higher internal stimulation) PET Scan studies by Dr. Debra Johnson

Activation  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Dominant pathway activated by dopamine (a sense of pleasure) AmbivertAmbivert Introverts 15% Dominant pathway activated by acetylcholine (alertness, attention) PET Scan studies by Dr. Debra Johnson

PET Scans Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Shorter, fast-acting, less complicated blood-flow patterns Involve areas related to variety, novelty, sensory processing AmbivertsAmbiverts Introverts 15% Longer, more complex blood-flow patterns Involve areas related to internal pondering

Extraverts 15% Data reduced in size and intensity AmbAmb Introverts 15% Data magnified in size and intensity #1 Data Modification  Arlene R. Taylor PhD Realizations Inc  Incoming data is triaged by the thalamus and sent on to the decoding center  In some brains, the data are altered by the Reticular Activating System

Extraverts 15% Crave stimulation Resistant to punishment Need lower doses of pain/sleeping meds AmbAmb Introverts 15% Overloaded quickly Sensitive to punishment Need higher doses of pain/sleeping meds #1 Modification, Cont’d  Arlene R. Taylor PhD Realizations Inc

#2 Energy Recharging  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Spend energy freely Recharged by interacting with outer world AmbAmb Introverts 15% Spend energy cautiously Recharge by interacting with inner world - takes much longer to recharge

#2 Recharging, Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Energy drained by an under- stimulating environment (bored, restless, delinquent) Need frequent breaks when trying to focus AmbAmb Introverts 15% Energy drained by over-stimulating environment (tired, depressed, sick) Can focus for long periods if interested

#3 Experiences  Arlene R. Taylor PhD Realizations Inc Extraverts 15% The more experiences the better Want to participate Prefer variety, high intensity, and different types of stimuli AmbAmb Introverts 15% Ponder experiences Want to observe Prefer less variety / intensity and more depth situations

#3 Experiences, Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Generally score higher on “positive” current-mood scales AmbAmb Introverts 15% Tend to dwell on the negative features of life / social situations

“Appointment? No, Thursday is out. How about never—is never good for you?”

#4 Aperture  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Can zoom in (as it were) Less easily distracted by surroundings when interested in the goal or task AmbAmb Introverts 15% Take in large amounts of data second for second More easily distracted by surroundings

#4 Aperture, Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Better short-term memory Tolerate high-tension situations better (e.g., exams) AmbAmb Introverts 15% Better long-term memory but recall may fail under stress or pressure Tend to be more sensitive to stimuli at all levels

#5 Norepinephrine  Arlene R. Taylor PhD Realizations Inc  A hormone synthesized by the adrenal medulla and implicated in resisting stress; and a neurotransmitter secreted in the brain stem that influences alertness, attention, moods, sleep, dreaming…  Levels tend to rise in the presence of chronic anxiety (e.g., two or more years)

#5 Norepinephrine, Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Lower levels innately Tend to do well at high-stimulation / high-excitement tasks (e.g., swat teams, ambulance) AmbAmb Introverts 15% Higher levels innately Tend to do better at tasks requiring careful attention (e.g., radar-screen tracking)

Impact on Teamwork  Arlene R. Taylor PhD Realizations Inc Anyone can choose to function on a team but your energy expenditures, comfort levels, and relative success may differ Society currently rewards two positions – both in ambiversion Some try to function in ambiversion regardless of innate preference to obtain societal rewards

Teamwork, Cont’d  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Ambiverts 70%Introverts 15% Like to be the boss Like teams and teamwork Resource specialists Independent workers, star performers, deal makers Independent workers, researchers, and writers

Empowerment  Arlene R. Taylor PhD Realizations Inc Extraverts 15% Ambiverts 70% Introverts 15% Introverts who try to keep up with extraverts may get sick; extraverts who try to function in introverted environments may fall asleep When possible, select environments that are optimum for your brain—and be sensitive to the differences of others
