对动物和人类的大量研究表明，学习受到形成关联时出现的背景或次要线索的影响。然而，很少有研究探讨关注情境的功能价值。我们首先证明，跳蛛（Phidippus Princeps）可以经过训练来躲避令人厌恶的、令人厌恶的马利筋虫（Oncopeltus fasciatus）。蜘蛛在第一次接触虫子时很容易攻击虫子，但在八次试验后明显不太可能这样做，尽管它们随后攻击并吃蟋蟀。接触以葵花籽饲养的无毒马利筋虫的蜘蛛，其攻击率并未出现同样的下降。接下来，我们通过训练蜘蛛在两种环境之一中避开马利筋虫，研究了次要上下文线索对蜘蛛学习的影响。当蜘蛛在不同于训练环境的环境中进行测试时，攻击率会增加，并且蜘蛛不再表现出对关联的保留。在与训练相同的环境中进行测试的蜘蛛继续避免攻击这些虫子。这些结果对捕食者和猎物的进化都有潜在的影响，并指出了研究情境依赖学习的重要性。版权所有2006。
A large number of studies on both animals and humans have demonstrated that learning is influenced by context or secondary cues that are present when an association is formed. Few studies, however, have examined the functional value of attending to context. We first demonstrated that jumping spiders, Phidippus princeps, could be trained to avoid aposematic, distasteful milkweed bugs, Oncopeltus fasciatus. Spiders readily attacked bugs on first exposure but were significantly less likely to do so after eight trials, although they subsequently attacked and ate crickets. Spiders exposed to nontoxic milkweed bugs reared on sunflower seeds did not show the same decline in attack rate. We next examined the effects of secondary contextual cues on spider learning by training spiders to avoid milkweed bugs in one of two environments. When spiders were tested in an environment different from the one in which they were trained, attack rates increased, and spiders no longer demonstrated retention of the association. Spiders tested in the same environment in which they were trained continued to avoid attacking the bugs. These results have potential consequences for the evolution of both predator and prey and point to the importance of studying context-dependent learning. Copyright 2006.
