Fig. 4. Bees failed to use a sequential priming cue to switch their choice of
colour. Top shows the arrangement of training stimuli. A yellow priming
stimulus in a tunnel with frontal baffles indicated that bees should approach
a yellow rather than a blue panel for a reward (+). A blue priming stimulus
indicated that the blue panel was rewarded (+) and the yellow panel unrewarded
(-). Bottom: seven bees failed to perform the task when trained for 180
trials. The group developed a slight preference for the yellow panel.
