Honey bees can rethink learned behaviours

Honey bees can adapt to changing situations and relearn tasks, but distractions can interfere with the process in a "strikingly similar" way to how it does in humans, according to new French research. Scientists trained bees to associate smells with rewards, then reversed the rules to test how flexibly the insects could adjust. Bees exposed to visual distractions struggled more, especially when the task required remembering information across a short time gap. Researchers say the findings suggest bees use more complex “awareness-like” learning processes than previously understood, adding to ongoing debates about consciousness in animals.

Can bees be aware? Using a demanding learning task, we show that honey bees behave as if awareness plays a role in their learning. Bees learned to reverse odor–reward associations, but only struggled when the task required linking events separated in time and when their attention was distracted. In this situation, learning broke down in a way strikingly similar to what happens in humans when awareness of cause–effect relationships is disrupted. These results suggest that bees do not rely solely on automatic learning but may engage awareness— pointing to an unexpected dimension of consciousness in an insect.
