Ch. 14 Biologically Based Factor Theory Flashcards
biological basis for personality
genetics, heredity y biology
- fetal activity + heart rate = predictor of temperament
- twin adoption studies (identical vs. fraternal)
- biological family members vs. adopted members
- brain imaging (EEG + MRI)
Hans J. Eysenck
Berlin, Germany
- moved to England to escape Nazies
- published “Dimensions of Personality”
- one of the most prolific/creative + controversial psychologists in the world
- researched that “intelligence was inherited” esp. intellectual capacities btwn ethnicities
- thought psychotherapy/counseling no benefit
**all evidence based research
four criteria for identifying a factor
requirements
(1) psychometric evidence
(2) heritability
(3) makes sense from theoretical view (deductive reasoning)
(4) must possess social relevance, related to social variables (ie, behavior, addiction)
psychometric evidence
reliable + replicable
- one of the requirements to be a factor
heritability
not learned characteristics
- one of the requirements to be a factor
hierarchy of behavior organization
most specific to most general:
(1) special acts or cognitions
(2) habitual acts or cognitions
(3) traits
(4) types or superfactors
special acts or cognitions
individual behaviors or thoughts that may or may not be characteristic of a person
- lowest level/most specific
(ie) student finishing a reading assignment
habitual acts or cognitions
consistent responses that recur under same conditions
- must be reasonably reliable or consistent
(ie) procrastination
traits
when habitual acts/cognitions are demonstrated across different conditions or situations
types/superfactors
cluster of primary traits
- made up of related traits
(ie) extraversion, neuroticism, psychoticism
general bipolar superfactors/types (3)
extraversion
neuroticism
psychoticism
factor
independent of each other
(ie) can be high extraversion but low neuroticism
extraversion
/intraversion
superfactor
- high score = high sociability, impulsiveness y optimism
- differences due to cortical-arousal level (inherited)
- extravert = low cortical-arousal level
- low baseline CAL/stimulation, need stimulation, seek it out to reach normal levels
neuroticism
/emotional stability
superfactor
- high score = anxiety, hysteria, depression y somatic symptoms
- diathesis-stress model
**think emotions
diathesis-stress model
genetic predisposition when combined w/ stressor elevate vulnerability to neurotic disorders
