Introduction to Dr. Raymond Cattell (01:24)

FREE PREVIEW

Dr. Raymond Cattell has taught at Clarke, Harvard, and the University of Illinois, exploring multivariate methods of analysis in personality structure. His books include "The Description and Measurement of Personality," "Factor Analysis," and "Personality: A Systematic, Theoretical, and Factual Study." He challenges other professionals to bring more objectivity and concreteness to the subject area.

Nature Versus Nurture (09:14)

The three phases of the origins of the field of personality include literary intuition, clinical observation, and experimental study. Psychologists debate the role of culture and genetics in the shaping of an individual's personality. Dr. Cattell discusses differences between fluid and crystallized intelligence factors.

Shaping Personality (08:52)

Limits are set by heredity and environment. Dr. Richard Evans and Dr. Cattell discuss research conducted by Edouard Seguin, Beth Wellman, Barbara Stoddard, Sigmund Freud, and William McDougall. Measure motivation objectively first through projective test, physiological measures, and learning phenomena.

Specification Equation (06:37)

The term erg does not have the preconceived associations connected to it. Cattell discusses experimental psychology nomenclature such as sentiment structures and attitudes. Plotting vector quantities allows psychologists to build additional calculations; there is no motivational theory today but there are methods.

Concept of Self (05:38)

Dr. Cattell discusses how his method of using specification equations accounts for the concept of self. Questions include how the self-sentiment controls other sentiments and the ergs, and how it came into existence. Cattell advocates measuring self-concept from year to year to watch it develop before creating laws and incorporating the Motivational Analysis Test.

Perception (05:05)

Study perceptual phenomena within a system by introducing a particular experimental condition and judgment. The Thematic Apperception Test (TAT) studies the drive caused by misperceptions. The stimulus response framework dictates response equals the function of organism and stimulus.

Learning (05:13)

Integrating learning and personality theory is premature because the reflex model needs to be reexamined. Cattell explains how a psychologist needs to study the organism before and after a change. Any experience is multi-dimensional.
