Pigeons responded in a successive-encounters choice procedure in which accessibility of the less profitable of two outcomes varied either in terms of probability of encounter or search time to encounter (keeping search time to the more profitable outcome constant). When the less profitable outcome was made more probable its acceptance became more likely. However, when search time to encounter the less profitable outcome was shortened, its acceptance became less likely. Both results are consistent with the delay-reduction hypothesis and with an optimality model developed for application to the successive-encounters choice procedure.
鸽子在连续遭遇选择程序中做出反应，在该程序中，两个结果中较不有利可图的结果的可及性在遭遇概率或遭遇搜索时间方面有所不同（使获得更有利可图结果的搜索时间保持不变）。当较不有利可图的结果更有可能出现时，接受它的可能性就更大。然而，当遇到较不有利可图结果的搜索时间缩短时，接受它的可能性就更小。这两个结果都与延迟减少假说以及为应用于连续遭遇选择程序而开发的最优模型一致。
