The Effect of Unpacking and Valence on Future Time Estimates

Prior research on support theory has shown that unpacking events leads to subadditivity of subjective probability judgments. The present research extends these findings to time estimates. We propose that the time estimate for a target event is systematically influenced by its representation (i.e., presenting a single event versus many sub-events) and its valence. Specifically, unpacking pleasant events leads to higher overall time estimates, corroborating findings in support theory. However, unpacking unpleasant events reverses this effect. Further, we demonstrate that perceived enjoyment (or pain) of an event mediates this pattern of results.
