Document Summary

Theoretical issues: meaningful individual"s differences (traits help us identify, differential psychology, no two personalities exactly identical, so much variability, so few traits, subtraits, different scores, stability over time, consistency across situations. Stability over time: traits are consistent overt time, but, manifestation of trait may vary, how it looks across time may differ, but same personality (i. e. , child playing alone, vs adult not going out) Consistency across situations: trait, situation (situationalism, situation x trait. Behaviour: trait: people do things because of certain traits, situation: where people find themselves in, to decide what they do; the context, context that contributes to behaviour, not the trait, different types of trait/situation interaction. Measurement issues: carelessness, faking on questionnaires, response set* (*discussed in lecture 2, barnum statements. Duplicate questions: people who take part in research study might not care, they might want credit in something, people might make honest mistakes on things.
