通过考察解释水平，诠释时间间隔和未来事件效价的双向关系。结果发现：时间间隔会影响人们对未来事件效价的感知，高解释水平事件在长时间间隔后发生的感知效价更好，而低解释水平事件在短时间间隔后发生的感知效价更好（研究1）；同时，未来事件效价也会反向影响人们对时间间隔的感知，相对于未来发生的正效价事件，负效价事件的感知时间间隔更短（研究2）。无论是时间间隔对未来事件感知效价的影响，还是未来事件效价对感知时间间隔的影响，解释水平均在其中起到中介作用。

英文摘要：

Consumers are constantly faced with decisions about the events that over time, and time seems to pervade every aspect of consumptive activity. However, the association between event valence and future time perception as well as the mechanism underlying the effects are still not clear. This study investigates thebi-directional relationship between the event valence and time interval perception and a possible mental construal process that may play a role in the associations. This research spans two studies. Study 1 was two 2×2 between-subjects experiments in which we manipulated the time interval （long, short） and event type （high-construal, low-construal）. One hundred and four undergraduate students from a major university in Beijing participated in experiment la and eighty three undergraduate students from a major university in Beijing participated in experiment lb. The results showed that the high-construal event was perceived more attractive perceived more attractive in near future. The results also of time interval on event valence perception. in distant future, while the low-construal event was demonstrated that construal level mediated the impact Study 2 was designed to investigate the inverse relationship of time interval and event valence. Forty-nine MBA students from a major university in Beijing participated in the study, in which we manipulated the event valence by ending with gain or loss. The results confirm previous research findings that event ending with loss looms shorter than event ending with gain occurred in the fixed time interval. Moreover, the mechanism underlying this effect is mainly driven by the construal level. That is, the event ending with gain will be construed at a high-level, which in turn makes time interval seem longer than the event ending with loss. These findings may have some important implications. First, the results extend the scope of construal level theory by showing that the association between event valence and temporal distance is a bi-directional relations
