Physiological Measures l o P h p a r g y “Meet the Fockers” (2004)
Electrodermal Activity (EDA) Derma= skin n Sweat conducts electricity (“GSR”) n Sweating due to Sympathetic Arousal n Emotional arousal (pain, anxiety, fear, guilt…) n Elevated baseline EDA & personality: n – Neuroticism
Lying & Sympathetic Arousal – Ancient Arabia n lick hot iron… if burn tongue, you are lying. – Ancient China & India n chew rice powder, spit out… if dry, you are lying. – Sympathetic arousal n inhibit digestion (e. g. saliva ) n activate metabolism respiration heart rate ventilation
Cardiovascular activity n Blood pressure —measure of stress reactivity n Heart rate —increases with anxiety, fear, arousal, cognitive effort
Cardiovascular activity n Cardiac reactivity – greater than normal increase in blood pressure and heart rate in response to a challenge – Associated with Type A personality: (impatient + competitive + angry/hostile) – Cardiac reactivity & Type A is associated with elevated risk of coronary heart disease
Brain Activity n Brain spontaneous electrical activity n Measure by electrodes on scalp (EEG) – Evoked Potential technique – Stimulus given, EEG measured – Evoked Auditory Potential (Auditory stimuli) – Evoked Visual Potentials (Visual Stimuli) – Waves patterns analyzed n Augmenting vs Reducing
P 300 a positive electrical potential that reliably occurs 300 milliseconds after a stimulus
P 300 n Discovered in 1964 n “Context updating” signature Schizophrenia - weak (abnormal amplitude) Borderline Disorder - delayed (abnormal latency)
P 300 impulsiveness - longer latency creativity, openness, curiosity “need for cognition” (intellectual curiosity) - higher amplitude P 300 a novelty orienting P 300 b surprise orienting
Brain Imaging Mapping brain structure and function l Positron emission tomography (PET) l Functional magnetic resonance imaging (f. MRI) l Deffusion Tensor Imaging l neural connectivity, mapping circuits

De Young et al. (2010)
Positron Emission Tomography
Neuroscience of extraversion ■ Johnson et al. (1999) • PET • 9 low (I), 9 high (E) • resting state only ■ RESULTS • Thalamus • Insula • Broca’s Area I: ↑ Anterior, E: ↑ posterior I > E ( talking to yourself !!)
Neuroscience of spiritual feelings Borg et al. (1999)
Neuroscience of spiritual feelings Borg et al. (1999) • Measured “self-transcendence” • Measured serotonin receptor density Conclusions • Weak serotonin binding • Weak gating of sensory stimuli [? ]
Other Physiological Measures n n Blood-born metabolites Monoamine Oxidaze (MAO) Immune system (e. g. , saliva swabs) e. g. Master et al. (2009). . . “Emotional Approach”
Emotional Approach Scale Master et al. (2009) n n After a profoundly upsetting event, I take time to figure out what I’m really feeling In especially trying circumstances, I delve into my feelings to get a thorough understanding of them When dealing with unusual challenges, I realize that my feelings are valid and important When coping with a really stressful experience, I acknowledge my emotions
Masters et al. (2009) Higher scores on the emotional approach scale significantly predicted… 1. Stronger immune response to laboratory stressor (physiological challenge) 2. Reduced recovery time after heart surgery
Other Physiological Measures n Cortisol –Kagan & Snidman (1991) n Testosterone (Ts) –Dabbs & Dabbs (2000) “crafty”, “sly”, “manipulative”
Hormones and Personality n Gender differences in personality – Agreeableness – Neuroticism (d=. 50) n Large gender differences in testosterone n Indivdual differences in testosterone within sex aggressiveness ? ?
Testosterone and dominance n Masur et al, 1992 – Post-victory surge n n High Ts Jobs: – Trial Lawyer – Actors – Athletes High Ts traits – Boastful, arrogant, devious
Testosterone and 2 D: 4 D l Fetal testosterone levels influence length of third finger. Estrogen influences length of first finger. l Adult digit ratio is useful in research as a proxy for fetal Ts exposure levels l Gender differences exist in 2 D 4 D: lower ratio in men.
Testosterone and 2 D: 4 D Meindl et al. (2012) l 2 D 4 D is correlated with adult facial masculinity. l 17 boys, aged 3 -11. l Facial dimensions recorded. l Data used to construct computer model of 2 D 4 D effects on facial shape.
Meindl et al. (2012) 2 D: 4 D
Testosterone and 2 D: 4 D l Most consistent personality correlates of Low 2 D 4 D: Sensation-Seeking Impulsiveness Aggression Interpersonal dominance / boldness Psychopathy l However, the associations are typically not very strong in magnitude and often fail to replicate.
Physiological Perspective Measures Theories • Eysenck, Gray: Extraversion • Zukerman: Senation-Seeking • Oxley / Amodio: Political Brain • Cloninger: Neurotransmitters • Davidson: Brain Asymmetry
Physiological-Based Dimensions of Personality Extraversion-Introversion Eysenck’s Theory: Introverts are characterized by higher levels of activity in the brain’s ascending reticular activating system. ARAS
Ascending Reticular Activating System 1950 s: ARAS controls amount of Cortical Arousal
Yerkes-Dodson Law: Optimal Arousal for a Task
Extraversion-Introversion n When given a choice, extraverts prefer higher levels of stimulation than introverts n Classic study by Russ Geen (1984) – Compared Extrav (E) and Introv (I) – Noise level preferences – Autonomic reactvity
Geen (1984) n Learning task n Distracting noise over headphones n Hi E, Low E subjects n Noise level chosen by Self, Intr, Extr n Measure stress reactions (physio)
Extraversion-Introversion n Geen (1984) Introverts and extraverts perform task… Best under their own chosen stimulation level Poorest under level chosen by opposite personality
Eysenck’s Theory of E No baseline differences in arousal. n Revised theory: n Extraversion-Introversion= Differences in arousal reactivity, not average levels of arousal
Reinforcement Sensitivity Theory (Gray, 1972; 1990) Jeffrey Gray, biopsychologist (rats) n Alternative theory of Extr and Neur n Focuses on two different brain systems: n v Beh Activation System BAS v Beh Inhibition System BIS
Approach Avoidance
Sensitivity to Reward and Punishment Behavioral Activation System (BAS): • Sensitive to reward cues • Activate/Energize/Get • Personality? impulsive Behavioral Inhibition System (BIS) Sensitive to threat cues n Inhibit/Stop/Evaluate n Personality? Anxious n
Integration of Gray and Eysenck theories n Impulsive =High extraversion, moderate neuroticism n Anxious =Moderate introversion, high neuroticism
BI S Gray’s Rotation of Eysenck N BA S E
But data supports a closer alignment to Eysenck BIS E S BA N
Larsen, Chen, Zelenski (2003) Learning task (fast colour naming) n Manipulate type of trial feedback: n – Punishment for wrong answer – Reward for correct answer n Measure BAS and BIS traits. RESULT? – BIS people did better in punishment condition – BAS people did better in reward condition
Size of bets placed after punishment vs reward n Pierce-Mc. Call & Newman (1986) IV= won versus lost. DV= Size of bet on next task. Result: After gain: After loss: E=I E>I

Sensation Seeking Marvin Zuckerman 1970 s-80 s n Sensory deprivation studies: Extraversion n Hebb’s Optimal Level of Arousal theory n SSSK =Diff in optimal level of arousal n Zuckerman’s Sensation Seeking Scale n Moderate positive correlation between extraversion and sensation seeking n
Sensation-seeking 4 factors (DEBT) n. Disinhibition n. Experience-Seeking n. Boredom Susceptibility n. Thrill and Adventure Seeking
Sensation Seeking n Physiological basis for sensation seeking – Monoamine Oxidase (MAO) – Enzyme that regulates neurotransmitters – After neurotransmitter binds to receptor need to stop it somehow – MAO puts the brakes on (at the receptor)
Sensation Seeking n Physiological basis for sensation seeking – Too much MAO= strong braking – Too little MAO= weak braking – High SSK have low MAO – Stimulation seeking is due to weak synaptic braking
Cortical Evoked Potentials and Sensation-Seeking n Augmenting is evident among high SSkers n Reducing is evident among low SSkers
MAO, Child Abuse, and Antisocial Tendencies n Interaction of gene and child maltreatment experiences n Low MAO + maltreatment= high risk to become antisocial n Caspi et al (2002)
