DISSERTATION RESEARCH: Jumping spiders and aposematic prey: testing the ecological consequences of a context shift effect during learned avoidancePI: Dr. Elizabeth M. JakobCo-PI: Christa D. SkowMany animals, including insects and spiders, can learn to associate environmental details with events that are important to their survival, such as the location or palatability of a food item. Numerous studies have shown that environmental background cues can be stored in memory as part of an event. This can create a problem when an animal tries to recall an important association across a changing environment. If background cues change between the time that an animal learns an association and when its memory of the association is tested, recall of the association can be compromised. Previous work by the authors demonstrated that the jumping spider Phidippus princeps can learn to avoid distasteful aposematic prey, but lose the association when environmental cues shift. They propose to broaden their study by testing the following: whether relearning the same association after a shift is faster than initial learning, whether subtle shifts in vegetation across environments result in impaired memory recollection as do more dramatic shifts, if background environmental cues alone can be used to make beneficial foraging decisions, and whether it is easier to recall an association after an environmental shift when a food item is more unpalatable and forgetting becomes more costly. This work will contribute to the understanding of the ecological consequences of attending to background cues during learning, predator psychology, and adaptive strategies of prey. The principle investigators have a strong track record of mentoring undergraduate researchers, and will involve undergraduates in all aspects of this research.

论文研究：跳跃蜘蛛和载体猎物：在学习回避的过程中测试上下文转移效应的生态后果：Elizabeth M. Jakobco-pi博士：Christa D. Skowmany动物，包括昆虫和蜘蛛，可以学会学会将环境细节与生存的事件相关联，例如食物或食品物品的生存。 大量研究表明，环境背景提示可以作为事件的一部分存储在内存中。 当动物试图回忆在不断变化的环境中的重要关联时，这可能会产生一个问题。 如果背景提示在动物学习关联的时间与测试关联的记忆之间发生了变化，则可以妥协关联的召回。 作者先前的工作表明，跳跃蜘蛛Phidippus Princeps可以学会避免令人讨厌的言语猎物，但在环境提示转移时失去了关联。 他们建议通过测试以下测试来扩展研究：转变后同一关联是否比初始学习更快，是否会导致跨环境中的植被的微妙变化会导致记忆回忆性受损，以及如果单独的背景环境提示可以使用更巨大的转变，那么如果可以将有益的伪造决定和在环境变化后更容易忘记，那么又一次地将其更容易忘记。 这项工作将有助于理解在学习，捕食者心理学和猎物的自适应策略期间参与背景线索的生态后果。 原则研究人员在指导本科研究人员方面有很强的记录，并将在本研究的各个方面涉及本科生。
