蜜蜂能够根据执行辨别任务的环境灵活地改变对视觉模式的偏好。这项研究调查了一天中的时间、任务以及两个参数同时作为调节蜜蜂对视觉模式偏好的上下文线索的影响。我们进行了三个系列的实验来研究这些相互作用。第一系列实验表明，经过训练的蜜蜂可以在中午休息以及夜间休息后，在喂食器和蜂巢处扭转它们的模式偏好。第二组实验表明，经过训练的蜜蜂能够在短短几分钟内改变它们的模式偏好，具体取决于它们是出去觅食还是返回蜂巢。第三系列实验表明，经过训练的蜜蜂可以在午间休息后以及过夜休息后显着逆转其在喂食器和蜂巢入口处的模式偏好；蜜蜂还可以学习在每个测试期间在喂食器和蜂巢入口处选择不同的模式。因此，训练对蜜蜂的日常昼夜节律施加了习得的模式偏好。这项研究表明，大脑很小的蜜蜂拥有复杂的记忆力，能够记住特定时间范围内的任务。因此，蜜蜂可以在时间和空间上“规划”它们的活动，并利用上下文来确定执行哪些操作以及何时执行。
Honeybees have the ability to flexibly change their preference for a visual pattern according to the context in which a discrimination task is carried out. This study investigated the effect of time of day, task, as well as both parameters simultaneously, as contextual cue(s) in modulating bees' preference for a visual pattern. We carried out three series of experiments to investigate these interactions. The first series of experiments indicated that trained bees can reverse their pattern preference following midday breaks, as well as an overnight break, at the feeder and at the hive. The second series of experiments showed that trained bees are able to reverse their pattern preference in just a few minutes, depending on whether they are going out to forage or returning to the hive. The third series of experiments demonstrated that trained bees can significantly reverse their pattern preference at the feeder and at the hive entrance following midday breaks, as well as after an overnight break; the bees could also learn to choose different patterns at the feeder and at the hive entrance within each testing period. The training thus imposed a learnt pattern preference on the bees' daily circadian rhythm. This study demonstrates that the bee with a tiny brain possesses a sophisticated memory, and is able to remember tasks within a temporal context. Honey bees can thus 'plan' their activities in time and space, and use context to determine which action to perform and when.
