Join Kate as she talks to Dr. Annaliese Beery, professor and member of the Psychology, Biology, and Neuroscience programs at Smith College. I wanted to talk to Dr. Beery because of her work on sex, gender, and estrus cycles in animal research. People often avoid studying females because they believe we are all too variable because of the effects of the menstrual cycle on physiology and behavior. Dr. Beery tells us how that isn't at all true! She also tells us about the research that shows that males are often the ones who are more variable.
