The Cap Pushing Response (CPR) is a free-flying technique used to study learning and memory in honey bees (Apis mellifera). The series of experiments outlined in this paper aimed to test w.ether honey bees exhibit the cognitive concept of “expectancy” utilizing the CPR in a w.ight differentiation paradigm. Five previous experiments in our laboratory have explored w.ether the concept of expectancy can account for honey bee performance and have all failed to support the cognitive interpretation. The first experiment examined if bees could differentiate betw.en the tw. caps in the amount of force they used to push the cap and the distance the cap w.s pushed w.en the caps w.re presented one at a time. The second experiment explored cap w.ight preference by presenting bees w.th a choice betw.en the tw. caps. The third and fourth experiments tested the bee’s ability to expect rew.rd or punishment based on cap w.ight. Results revealed that bees w.re found to have a strong preference for the light cap and therefore w.re not able to expect rew.rd or punishment based on cap w.ight. These experiments contribute to the debate on w.ether bees have “cognitive” representations and continue to support the behaviorist interpretation.
