Abstract

Sensory preconditioning means that reinforcement of stimulus A after unreinforced exposure to a compound AB also leads to responses to stimulus B. Here, we describe and analyze sensory preconditioning in an insect, the honeybee Apis mellifera. Using two-element odorant compounds in classical conditioning of the proboscis extension reflex, we found (i) that sensory preconditioning is not due to stimulus generalization, (ii) that paired, but not unpaired, presentation of elements supports sensory preconditioning, (iii) that simultaneous, but not sequential, exposure to the elements of the compound supports sensory preconditioning and (iv) that a single presentation ofthe compound yields maximal sensory preconditioning, The results are discussed with respect to configural and chain-like associative explanations forsensory preconditioning, We suggest an experience-dependent step of compound processing, establishing configural units, as an additional explanation for sensory preconditioning.
