Does bee vision work at a range of speeds?

One way in which the visual systems of vertebrates and invertebrates may differ is in the relative role of active vision strategies. Some aspects of human vision are parallel which goes some way to explaining the speed at which we can make scene judgements. Active visual strategies are likely to be slower because either a particular filter has to be moved over the scene, or a particular pattern of movement is required to generate input. Nityananda et al address this question by asking which perceptual judgements can be made by bees when stimuli are presented for very brief periods. They find that ‘simple’ colour and orientation judgements can be made with a 25ms presentation time. However, more complex judgements (perceiving a complex predator-like shape) are not made even with 100ms presentation times. This raises the fascinating question of how bees shape their perception (i.e. active vision) when making such judgements and whether such strategies are learnt at the same time as the patterns themselves.
