Could anyone help with these three quick questions please?

1. Under what conditions would you expect self-ratings to be most similar to informant ratings? When would you expect these two sets of ratings to be most different from each other?

2. The findings of Gosling, et al. (2002) demonstrate that we can obtain important clues about students' personalities from their dorm rooms. What other aspects of people's lives might give us important information about their personalities?

3. Suppose that you were planning to conduct a study examining the personality trait of honesty. What method or methods might you use to measure it?
