Fig 4. Learning indices.

Fig 4

The learning indices (LI) were averaged across the two test trials for data shown in Fig. 3a-c. The LIs clearly show that in the before section, the CS+ and the CS- trials did not differ, whereas for both during section and after section, bees responded more to the CS+ than to the CS- (positive LIs). There was no statistically significant difference between during section and after section, indicating that bees did not alter their hissing behaviour by much at the predicted timing of the shock. Letters indicate statistical difference, RM-ANOVA followed by Fisher LSD-post hoc test, p<0.0001. n = 104 bees.
