PSYB30H3 Study Guide - Midterm Guide: Lexical Hypothesis, Factor Analysis, Impulsivity
Document Summary
Act nomination- procedure designed to identify which acts belong in which trait category. Prototypical judgement- identifying which acts are central to, or prototypical of, each trait category. Recording of act performance- securing information on the actual performance of individuals in their daily lives. Lexical approach- all traits listed and de ned in the dictionary from the basis of describing differences among people. Statistical approach- uses factor analysis or similar statistical procedures, to identify major personality traits. Theoretical approach- in which researchers rely on theories to identify important traits. Lexical hypothesis- all important individual differences have become encoded within the natural language: example people understand description when these words are used: dominant, creative, reliable, cooperative, hot-tempered, self centred. Natural language : according to the lexical approach, trait terms are extraordinary when it comes to communication with others, two criteria for identifying important traits- synonym frequency and cross- cultural universality.
