The trial-spacing effect in olfactory patterning discriminations in honeybees.


Harnessed bees conditioned to associate odors and sucrose reward learn to discriminate between olfactory mixtures and their odor components in negative (NP: A+, B+, AB-) and positive (PP: A-, B-, AB+) patterning experiments. They thus extend the proboscis to the reinforced (CS+) but not to the non-reinforced (CS-) stimuli. Using the same protocol, we… (More)
