Objects are often not fully visible in everyday life. Human beings are capable of processing the complex visual information related to “incompleteness” because our visual environment is primarily composed of opaque objects that can overlap and partially hide each other. Scientists believe that many nonhuman species are also able to deal with “incompleteness”…
Dr. Pepperberg is a Research Associate and Lecturer at Harvard University working in the field of animal cognition and communication, specifically in African Grey parrots. In 1977, Dr. Pepperberg began her work with Alex, her first Grey parrot research subject. For 30 years, Irene and Alex investigated concepts such as shapes, colors, sizes, and numbers, revolutionizing what the world knows about avian cognition. Following in his footsteps are the Grey parrots, Griffin and Athena. Currently, Dr. Pepperberg’s work is entirely supported by The Alex Foundation.
“Griffin”, a grey parrot in Dr. Irene Pepperberg’s animal behavior and avian cognition lab, could wait up to 15 minutes for a better quality reward, even though both treats offered were preferred food items. Griffin displayed delayed gratification for longer than any previously tested avian subject including Goffin’s cockatoos. Fifteen minutes was the longest time evaluated, not necessarily the longest length of time Griffin could wait.
