PSY 216 Chapter Notes - Chapter 14: Hans Eysenck, Sensory Threshold, Municipal Disinvestment
Document Summary
Worked at hospital treating patients with a variety of psychological symptoms. Found many clinical psychology programs inadequate and unscientific. Argued for the efficacy of factor analysis as the best method of representing the known facts of human personality. Based his taxonomy in biology and factor analysis. Derived only 3 dimensions of personality extraversion/introversion, neuroticism/stability, and psychoticism/superego. Evidence for the biological basis comes from temperament, behavioral genetics/heritability, and brain measure research (eeg when brain activity occurs and fmri where brain activity is). Criteria for identifying factors (1) psychometric evidence for the factors existence must be established. (2) the factor must possess heritability and must fit an established genetic model (3) the factor must make sense from a theoretical view. Defined in terms of significant intercorrelations between different habitual behaviors (4) types/superfactors: made up of several interrelated traits. (most general) All three factors are part of normal personality structure.
