Document Summary
Desires/needs carry across settings & are presumed to be casual. Two basic formulations of traits: internal causal properties. Helps to rule out other causes for behaviour: descriptive summaries causality. (they summarize behavioural trends) Traits are descriptive summaries of one"s attributes without assuming internality/ Traits=categories of acts: categories. prototypical of, each trait category. individuals in their daily lives. Pros: act nomination: a procedure designed to identify which acts belong in which, prototypicality judgement: identifying which acs are most central to, or most, recording of act performance: securing of information on the actual performance of. Helps study the meaning of hard to study traits. The lexical approach to identifying traits starts with the lexical hypothesis: all important individual di erence have become encoded within the natural language. Cons:-some traits are ambiguous: cross-cultural universality: the more important is an individual di erence in human. The statistical approach is to identifying important traits starts with a pool of personality items.
