The same is true for stars; by observing. the color of stars, we can determine which stars are hot and which stars are cool. If we know the temperature of a star, and how far away it is (see the âMeasuring. Distances Using Parallaxâ lab), we can determine how big a star is.
Attitudes can positively or negatively affect a person's behavior. A person may not always be aware of his or her attitude or the effect it is having on behavior. A person who has positive attitudes towards work and co-workers (such as contentment, friendliness, etc.) can positively influence those around them.
That said, psychologists who study attitudes agree that environmental factors--in particular, the nonshared environment, or a person's individual experiences outside the family, usually examined via twin studies (see page 46)--are consistently stronger in predicting attitudes than genetic ones, at least among adults.
