What is the goal of physiological approaches?
try to find physiological factors that influence and are influenced by personality characteristics
What are the pros of measuring electrical responses by using electrodes?
noninvasive
no discomfort
What is the con of measuring electrical responses by using electrodes?

measures electrical impulses generated by movement of muscles
facial electromyography
Galvanic Skin Response (GSR) measures _________ activity
electrodermal
GSR measures responses to what 3 things?
- sudden noise
- pain
- high arousal emotions
measure of stress reactivity
blood pressure
increases with anxiety, fear, arousal, and cognitive effort
heart rate
degree of increase in blood pressure and heart rate under stress
cardiac reactivity
Cardiovascular activity is tested with what?
backward serial subtraction
People with a type A personality have greater _________
reactivity
Electrical activity in the brain is measured with _______
electrodes (EEG)
maps structure/function of brain; PET, fMRI
brain imaging
Brain imaging measures _______
blood flow
hormone associated with risk-taking, sexuality, and dominance
testosterone
hormones associated with affiliation and agreeableness
progesterone and oxytocin
hormone that increases with distress
cortisol
Differences in physiology indicate difference in _______ functioning, and create differences in _________
psychological; personality
The relationship between personality and physiology will depend on your ________ to your physiological responses to the environment
adaptation
What does the reticular formation detect?
changes in physiological arousal
claimed that the Ascending Reticular Activation System (ARAS) is the gateway from sensation to arousal
Eysenck
individuals vary in how much arousal they need to feel comfortable
optimal arousal (Hebb)
What are the 2 hypothesized brain systems?
behavioral activation system (BAS)
behavioral inhibition system (BIS)
brain system responsive to reward; regulates approach behavior; leads to high impulsivity; associated with extraversion
behavior activation system (BAS)
brain system responsive to punishment; regulates “avoidance” behavior; leads to high anxiety; associated with neuroticism
behavior inhibition system (BIS)
The ______ system (amygdala) produces automatic emotional responses from incoming sensory input
limbic
The ___________ allows conscious attempts at emotion regulation
prefrontal cortex
The left hemisphere of the prefrontal cortex is associated with ________ motivation and _______ affect.
approach
positive
The right hemisphere of the prefrontal cortex is associated with _______ motivation and _________ affect.
avoidance
negative affect
BAS sensitivity is associated with ________ and ________
impulsivity
reward seeking
BIS sensitivity is associated with _______
anxiety
The amygdala, hippocampus, and parahippocampal circuit are associated with what big 5 personality trait?
Neuroticism
part of the brain associated with memory; compares current vs. previous experience; OK not OK check
hippocampus
greater activation of the cingulate gyrus and dorsal (medial) prefrontal cortex is associated with what big 5 personality characteristic?
neuroticism
