Learning in an insect herbivore: How rewards affect color and odor discrimination in a hungry locust. Dr. Martin S. Shapiro California State University, Fresno Dr. Spencer Behmer Oxford University Corlisa Belt Oxford University
Experiment 2 Odor Discrimination: Peppermint and Lemon. Amount of reward: 3 mg vs. 12 mg. Nine choices: Equated experience with both options. Reversed: Rewards reversed for each option for an additional 9 choice runs (18 choices in total). n = 12
Summary Good choice results. Good discrimination of color and odor. (odor showed less bias.) Approach time was significant in all three experiments. by latency
Continuing work at Cal State Fresno with Schistocerca americana
Future Experiments Delay to Reinforcement. –Self Control. –Risk Sensitivity. –Energy Expenditures. Effects of Carbohydrates and Proteins on Learning. –Nutrient-Specific Deprivation. –Risk Sensitivity with variability in specific nutrients.
