Inside Pepperberg’s Lab: Do Parrots Show Remorse?
When a prestigious behavior journal welcomed scientists to submit anecdotal observations of nonhuman actions that suggested possible comparisons with those of humans, a recent episode with African grey Griffin sprung to mind. Did Griffin show signs of remorse after delivering an unexpected bite?
Inside Dr. Pepperberg’s Lab: Can Parrots Win at the “Shell Game?”
How good are you at the “shell game”… can you follow an object that is shuffled around under shells or cups? Imagine being tested on your ability to track not just one colored object but four! Dr. Irene Pepperberg shares the results of how African grey Griffin’s visual working memory stacks up when compared to adults and children.
Inside Pepperberg’s Lab: Parrots Adapt During Coronavirus Lockdown
Dr. Irene Pepperberg fills us in on how African greys Griffin and Athena, as well as she and her staff, are handling their “new normal,” albeit hopefully a temporary one. She also dishes on how they found some creative ways to celebrate two big milestones — the birds’ birthdays!
Inside Pepperberg’s Lab: Life In The Time Of Coronavirus
What’s an academic science lab to do when e-mails from the administration start popping up stating in-person instruction was to cease immediately, followed by directives to vacate the campus in light of the ongoing COVID-19 crisis? What if said science lab was home to a flock of parrots known around the world for their contributions to the study of cognitive behavior? Dr. Irene Pepperberg and her research assistants found themselves in a scramble to ensure everyone— birds and humans — found safe places to stay. See where everyone is now.
Comparative Cognition — The Joys & Difficulties
A lot of planning goes into creating ways to test the parrots’ intelligence to see how they perform on tasks compared to the results of those undertaken by children and primates. But what happens when two hands are required to solve a problem? Dr. Pepperberg describes the challenges and possible solutions to an intelligence test to circumvent the fact that parrots are hands-free.
Inside Dr. Pepperberg’s Lab: Can African Greys Spot Which Container Holds More Liquid?
African grey parrots Athena and Griffin are tasked with the challenge of tracking the larger amount of liquid that is poured into various containers to test their grasp of the concept of “overconservation,” where the experimenter starts with different amounts and tests whether the subjects can track the larger amount after various transformations. See where the parrots succeeded as well as what tended to slip them up on this highly challenging task.
Friends or Frenemies—How Well Do Parrots Interact with Each Other?
For parrots in the wild, flock dynamics include bonded pairs, siblings, and flockmates who forage for food together, play together, or simply co-exist with one another (and, of course, help keep a lookout for predators). What about companion parrots? Will two parrots get along? Dr. Pepperberg dishes on the interactions among her African grey parrots, as well as explains why it can be challenging so to predict how flock dynamics will play out inside the home.
Inside Pepperberg’s Lab: Vet Visits Are Essential
Dr. Pepperberg shares her experiences with taking African greys Griffin and Athena (and Alex before them) to the vet for their well-bird health checkups, which, with their verbal communication prowess, has led to some interesting vet interactions.
Inside Dr. Pepperberg’s Lab: African Grey Athena’s Unexpected Health Issue
Dr. Pepperberg dishes on a recent health scare she experienced with African grey Athena. She gives us a first-hand account of dealing with Athena’s sudden feather issues to remind us that seemingly minor or temporary changes in a parrot’s environment can affect the bird’s health in unexpected ways.
Inside Pepperberg’s Lab: Vocal Turn-Taking In Parrots
Do birds take turns when conversing or is this a uniquely human skill? Dr. Irene Pepperberg addresses birds’ use of “countersinging” and “duets” as forms of vocal communication.
Let’s Talk About The Weather: Parrots & Rainstorms
Dr. Pepperberg dishes on how her birds, African greys Griffin and Athena, and Alex before them, have noticeably different reactions to inclement weather. She also reveals that some wild birds have a special pressure-sensitive organ that makes them particularly in tune with barometric pressure.
Do Parrots Understand What You Are Saying?
Can birds understand what their people are saying and/or understand what he or she is saying? Dr. Irene Pepperberg says the answer depends on the type of interactions parrots have with their owners. Discover how the way you interact with your feathered companion, as well as flock dynamics, can influence parrot communication.
Pepperberg’s Lab: African Greys Get a Skyline View
Dr. Pepperberg takes us inside her Harvard lab, where African grey parrots Griffin and Athena call home. We also get a look at their cushy temporary quarters on the building’s eighth floor, complete with a breathtaking view of the Boston skyline. The panoramic view comes with potential visual encounters with a pair of red-tailed hawks—see how the greys react.
Pepperberg’s Lab: When Parrots Go “Off-Script”
Dr. Pepperberg’s work with parrots revolves around reproducing behaviors using scientific methods to attain statistical significance. Of course, parrots being parrots, there are plenty of incidents where one of her African greys says or does something that perfectly captures their mood or preference, but which cannot be scientifically documented. African grey Griffin, like Alex before him, certainly knows how to get his point across to Pepperberg and her research students. See how these anecdotes provide interesting insights into how the mind of a parrot may work.
Inside Dr. Pepperberg’s Lab: When Favored Treats Aren’t Enough
What happens when a parrot is asked to repeat a task over and over …will the prospect of receiving a favorite treat be enough to keep him going? Or do parrots, even when lavishly rewarded, reach their boiling point? See how African grey parrot Griffin fared when tasked with verbally labeling the same objects repeatedly during the course of several days.
Inside Dr. Pepperberg’s Lab: Why Study Parrot Cognition?
Studies of nonhuman cognition have made, and continue to make, major contributions to our understanding of the origins and evolution of human cognitive processes, and much more. Parrot cognition studies in particular have a positive impact on pet bird care, conservation, child cognitive therapies, and even artificial intelligence. See what drives Dr. Irene Pepperberg’s passion for parrot research.
Inside Pepperberg’s Lab: Mutual Exclusivity In Parrots — A Special Case Of Inference
Dr. Irene Pepperberg tests African grey parrot Griffin’s cognitive skills, going beyond the concept of “inference by exclusion” to the trickier concept of mutual exclusivity (ME). Would Griffin understand that an object could, for example, be both “green” and “wool,” or “blue” and “wood?”
How Good is a Parrot’s Long-Term Memory?
How well do parrots remember situations, other parrots, and people over the course of their long lives? Dr. Pepperberg, gives us a rundown on research that points to parrots as having brain areas that function in ways similar to the human cortex, and how their extremely high neural densities enable advanced cognitive processing—which requires good memory.
Inside Pepperberg’s Lab: Putting Parrots’ Inferential Knowledge To The Test
When her colleagues at Harvard questioned Dr. Irene Pepperberg’s 2-cup test success that showed parrots are capable of inferential knowledge to make decisions, Pepperberg and students at her cognitive behavior research lab upped the ante from the 2-cup test to 3- and 4-cup tests. They once again put African grey Griffin to the test. See how Griffin fared, especially when a coveted Skittle treat reward was at stake.
Inside Pepperberg’s Lab: Fish & Parrots Outperform Apes & Monkeys
If you put parrots (specifically, African grey parrots), fish, monkeys and apes to the test on who could figure the fastest way to procure two rewards instead of one, who would come out on top? Dr. Pepperberg and friends of her cognitive behavior research lab recently modeled a test for her flock to see how they would fair in a choice-themed task inspired by wrasse fish, and tested on primates as well.
