superfactors or types
Eysenck\'s approach to research that begins w/ a hypothesis, then deduces testable predictions from the hypothesis & then gathers data to determine whether the predictions are accurate
hypothetico-deductive reasoning
the emotional, motivational, and non-ability related cognitive aspects of behavior

*The focus of Eysenck\'s formal theory of personality.

temperament

historical roots of Eysenck\'s theory was based on this
Jung\'s hypothesis:
-Introvert vs. Extrovert


these types of people are usually characterized by symptoms of anxiety, sensitivity & fatigue
(also called Dysthymic)


Neurotic Introvert
these particular types of people are often experience symptoms of hysteria or some other external form
Neurotic extrovert

\'hysteric\'- refers to the disordered neurotic extrovert

Eysenck states that psychiatric patients (& personalities in general) were described by 3 major independent types or superfactors

N- Neuroticism vs. Stability: most severe patients labeled Dysthymic(depression)
E- Extroversion vs. Introversion: most severe patients labeled Hysteric
P- Psychoticism:
those patients who suffered from a psychotic disorder




Eysenck was intrerested in the biological bases of personality and borrowed ideas from Pavlov and Hull
ideas about excitation and inhibition
a decrease in a conditioned response due to muscular/neural fatigue (Clark Hull)
Reactive Inhibition
a general class of theories that assumes behavior is partly a function of the general state of arousal (excitation) or derousal (inhibition) of the cortex and/or other brain structures
Arousal theory

(Introvert\'s brain has higher levels of neural activity; EP\'s are strong and are generated quickly; reactive inhibitions develop slowly and dissipate quickly

Controls introversion/ extro-version

responsible for patterns of excitation and inhibition of the cerebral cortex

Ascending reticular activating system (ARAS)
Controls neuroticism

regulates emotional expression & controls the autonomic nervous system

Visceral Brain (VB) or Limbic System

In order to demonstrate a bio basis for P, E, and N,
4 criteria must be met:
1-data must demonstrate heritability
2-confirm similar traits of P,E, and N in non-human animals
3-evidence of P,E, and N must be found cross-culturally
4-P,E, and N must be found to be stable over time


According to Eysenck, this is caused by abnormally high levels of the 3 superfactors that characterize all personality. Quantitative in nature
psychopathology
Eysenck believed psychotherapy
should always be derived from empirical data and principles that have been shown to be effective
Criticisms of Eysenck:
1- too subjective
2- behavior is not as consistent as factor theories suggest
3- excessive emphasis on groups and averages

Eysenck\'s contribution:

farewell to mythical psychology:



Eysenck emphasized scientific, empirical research and challenged other psychologists to subject their theories to the same scrutiny
