Helping behavior is roughly defined as providing aid or benefit to another person in which it doesen't matter what the motivation of the helper is, only that the recipient is assisted. In this experiment, that is the dependent variable. Young children will attempt to imitate those models when they are helping, like a teaching of sorts, but won't have nothing to see in them if the models aren't engaging in this helping behavior.
In The Crucible, the idea of goodness is a major theme. Almost every character is concerned with the concept of goodness, because their religion teaches them that the most important thing in life is how they will be judged by God after they die.
