Desires that conflict with overarching goals or values are known as temptations. Self-control dilemmas occur when long-term goals and values clash with short-term temptations. Counteractive Self-Control Theory states that when presented with such a dilemma, we lessen the significance of the instant rewards while momentarily increasing the importance of our overall values. When asked to rate the perceived appeal of different snacks before making a decision, people valued health bars over chocolate bars. However, when asked to do the rankings after having chosen a snack, there was no significant difference of appeal. Further, when college students completed a questionnaire prior to their course registration deadline, they ranked leisure activities as less important and enjoyable than when they filled out the survey after the deadline passed. The stronger and more available the temptation is, the harsher the devaluation will be.
