Document Summary

Identifies which acts belong in which trait category: e. g. category impulsive think of someone who is impulsive and their actions, 2) prototypicality judgment. If we find a trait that is important in identifying individual differences than we should be able to see that identifier in our culture , and also in others. Lexical approach: limitations: very tedious to go through the dictionary, many traits are ambiguous, obscure, or difficult, e. g. Identifies groups of items that covary (go together), but tend not to covary with other groups of items: factor loading: Index of how much a factor explains a variable in factor analysis (-1 to 1) Dads vs. cads critical individual difference: strengths coincide with strengths of a theory, and weaknesses coincide with the weaknesses of a theory, evaluating approaches for identifying important traits. Heritability and 2) identifiable substrates (where they come from: behavioral genetic evidence, p, e, and n have moderate heritability.
