  • Title: Uncertainty processing in bees exposed to free choices: Lessons from vertebrates.
    Author: Anselme P.
    Journal: Psychon Bull Rev; 2018 Dec; 25(6):2024-2036. PubMed ID: 29435964.
    Abstract:
    Bees tend to avoid or to show indifference to uncertain ("risky") relative to certain ("safe") food rewards, whether in nectar volume or in nectar concentration. The unattractiveness of uncertain food rewards is also sometimes independent of the energy budget of bees. This pattern of responses seems to differ from that observed in mammals and birds, which may exhibit a strong preference for the uncertainty over the certainty of food delivery on a given trial in dual-choice tasks. Upon analysis of the conditions that determine preference and aversion for uncertain food rewards in "higher" vertebrates, I attempt to demonstrate that bees react to uncertainty in a similar way. It is argued that, because of their social organization and of the type of resources they seek, bees are essentially exposed to situations in which "higher" vertebrates find reward uncertainty unattractive as well. The nature of their representation of food distribution is discussed, and it is suggested that scout bees may differ from recruits with respect to uncertainty processing.
