Document Summary
Lexical and theoretical approach to figure out how many traits there are. Lexical approach- dictionary- 20,000 different trait terms: narrow down to the core traits. Statistical starts off with terms (lexical), then collect data (look for patterns of covariation- factor analysis- correlations in data: factor analysis shows the traits that are strongly related (synonymous) We don"t really do theoretical approach anymore we"re more in statistical: statistical approach to identify basic traits, factor analysis lumps things together- just different components of larger. Taxonomies: eysenck- boiled down 20,000 trait terms to three main traits (everything else is subcomponent, cattell- narrowed down 20,000 to 16 clusters/groupings (one cluster would be nice, warm, kind, polite, etc. ) Each of the 16 would have a fair amount of variation within it: costa and mccrae- 5 factor model. We call it a model because we"re modelling a solution- how to group together all the different correlations. Eysenck and cattell modelled them with 3 and 16 factors,
