We generally think of learning as a means to track change in the environment. How will economics and change favor tracking and which conditions favor constant choice, like the flower constancy we see in bumblebees? How does change in the environment affect how animals weight different types of information? We are using both bumble bees and flies to address some of these questions. With bees we are applying classic tracking models from foraging theory to look at how change, innate bias, and other factors affect when new information will be acquired and applied. We are also looking at decision rules and theories from human economics to predict patterns of behavior in foraging bees.
