Most environments confront human and other animals with choices.
These can range from a major corporation making financial decisions to ducks foraging for food on a lake. My research examines the way the distribution of resources in an environment determines humans and animals choices. Controlled environments are arranged in which animals forage for food by making different responses. Each response might produce, for example, different rates, amounts, or delays of food. Other research investigates how the consequences of choices influence judgements about ambiguous stimuli.
