Helpful Hopefulness: The Effect of Future Positive Emotions on Consumption
研究发现，体验未来导向的积极情绪（如希望）能减少不健康零食消费，而过去或现在导向的情绪（如自豪、快乐）则无此效果，且未来导向的消极情绪（如恐惧）也无此作用。
Although positive affect may enhance self-control, some research suggests that this is not always the case. To clarify this relationship, we investigate the role of temporal focus on the effect of specific positive emotions on self-control dilemmas in snack consumption. In four studies, we demonstrate that participants experiencing a future-focused positive emotion (i.e., hopefulness) consume less unhealthy food and have lower preferences for unhealthy snacks than those in a past- or present-focused emotional state (i.e., pride, happiness). We demonstrate the role of temporal focus through its natural occurrence in emotion-induction essays (study 1), chronic temporal focus (study 2), and manipulation of anticipated versus retrospective emotional states (study 3). A fourth study demonstrates that self-control benefits do not arise from future-focused negative emotions (i.e., fear) as they do from future-focused positive emotions. These results suggest that consumers may benefit from adapting the temporal focus of positive emotions to the future.
