Miscellany
Animal cognition researcher Irene Pepperberg wrote in her study of the African gray parrot Alex that the intelligent bird often became restless when asked to focus on a single task: “He will cease to work, begin to preen, or interrupt with many successive requests.” In 1996 Alex appeared on the television show Turning Point to demonstrate that he could name the colors, shapes, sizes, and materials of different objects. In the middle of this exercise, he began to respond to Pepperberg’s questions with remarks like “Want to go back” and “Want to go eat dinner.”
