Figure S3 from Perception of contextual size illusions by honeybees in restricted and unrestricted viewing conditions

Individual and pooled performance of bees during the learning phase in experiment 2. Black crosses indicate pooled data for all bees (n = 10) in the restricted viewing condition (means ± SEM). Dashed coloured lines represent each individual bee's performance over the 80 conditioned trials. Dashed line at 0.5 indicates the chance level performance.
