Document Summary
His parents split up when he was 9. Analyzed the personality of voters and contributed heavily to political psychology. Concerned with discovering underlying dimensions of personality, advocated factor analysis. Suggested three source traits as opposed to cattell"s 16. Denotes a hierarchical trait model of personality. Evidence of cortical arousal in introversion and extraversion. Individual who is introverted has higher cortical arousal rate at rest than extraverted individual. Introverts need less stimulation to achieve the desired level of cortical arousal, however. It takes extroverts longer to learn (in school, in classical conditioning task, those in jail more likely to be populated by extroverts) Extroverts report higher levels of subjective well-being. Extroverts socialize are more active/vigorous and more sensitive to positive comments. Happiness requires increase in positive affect and decrease in negative affect. Heritability index= degree to which characteristic has travelled genetically. Eysenck"s theory is comprehensive, but it is primarily biological.
