 Videos of animals engaged in surprising behaviors, such as an orangutan washing clothes and sawing wood or a dog using buttons to “speak” (see  Other Internet Resources),  might suggest that these animals are smart or intelligent. The idea that some animals are smarter than others might also lead you to expect that research in animal cognition focuses on animals such as chimpanzees, elephants, dolphins, dogs, or ravens—all species that often make the news with reports of their amazing abilities. But animal cognition research is just as interested in research on worms, honeybees, snakes, stickleback fish, chickadees, and spiders, though there remains quite a bit of cognition research on the behaviorist standbys of pigeons and rats.
