The classical olfactory conditioned response of the honey bee, involving the extension of the proboscis on tarsal contact with sucrose solution, has been investigated. The bee showed generalization between two similar aromas but distinguished the third. The bee clearly showed experimental extinction, differentiation, and conditioned inhibition, all of which were temporary and not retained until the following day. Thus, spontaneous recovery was observed. The experiments also suggest the occurrence of a conditioned response of the second order.
