    In this episode, we described a channel factor as an aspect of the situation that bridges between an intention and action and has a major impact on behavior. In Milgram's obedience study, a channel factor was the "gradual escalation" of shocks. In the Good Samaritan study, "time to help" was critical. Which of the following aspects is a channel factor that we described in the case of organ donation?
