    Study Notes

    Factor Analysis

    • Factor analysis is a statistical method used to reduce a large set of variables into a smaller set of underlying factors that summarize the data.

    Principal-Components Method

    • The Principal-Components Method is a type of factor analysis used to extract the most important information from a large dataset and condense it into a smaller set of factors.

    Guilford's Factor Analytic Approach

    • Guilford's factor analytic approach focused on identifying the structure of cognitive abilities, particularly in the area of intelligence.

    Cattell's Source Traits

    • Cattell's Source Traits represented the underlying, stable aspects of personality that are relatively enduring and resistant to change.

    NEO PI-R

    • The NEO PI-R is a personality inventory used to evaluate individual differences in personality across six domains: neuroticism, extroversion, openness, agreeableness, conscientiousness, and honesty-humility.

    NEO PI-R: Extroversion (E) Domain

    • The extroversion (E) domain of the NEO PI-R measures aspects of personality such as Assertiveness, Excitement-seeking, Anger, Activity, and Gregariousness.

    NEO PI-R: Openness (O) Domain

    • The openness (O) domain of the NEO PI-R comprises six facets: Fantasy, Aesthetics, Feelings, Actions, Ideas, and Values.

    NEO PI-R: Likert Format

    • The NEO PI-R uses a 5-point Likert format, ranging from "Strongly Disagree" to "Strongly Agree", to measure an individual's level of agreement with a particular statement.
