Figure 4. Deficits in olfactory learning predict lack of intact extinction performance.

(A) No association between sensitivity to sucrose (US) and orientation behavior was found. (B) In contrast, reduced olfactory learning ability, a population-level characteristic of old foragers (Fig. 1A,B), is a predictor of orientation behavior in a cohort comprising mixed-age forager groups. Workers that oriented towards a novel location C had the higher median learning ability, outperforming the workers that oriented towards location A, the location bees were trained to extinguish. Graphs indicate medians and interquartile ranges, the asterisk denotes significance (Kruskal-Wallis test).
