Product Description:
The Alex Studies Cognitive and Communicative Abilities of Grey Parrots Irene Maxine Pepperberg Can a parrot understand complex concepts and mean what it says? Since the early 1900s, most studies on animal-human communication have focused on great apes and a few cetacean species. Birds were rarely used in similar studies on the grounds that they were merely talented mimics--that they were, after all, 'birdbrains.' Experiments performed primarily on pigeons in Skinner boxes demonstrated capacities inferior to those of mammals; these results were thought to reflect the capacities of all birds, despite evidence suggesting that species such as jays, crows, and parrots might be capable of more impressive cognitive feats. Twenty years ago Irene Pepperberg set out to discover whether the results of the pigeon studies necessarily meant that other birds--particularly the large-brained, highly social parrots--were incapable of mastering complex cognitive concepts and the rudiments of referential speech. Her investigation and the bird at its center--a male Grey parrot named Alex--have since become almost as well known as their primate equivalents and no less a subject of fierce debate in the field of animal cognition. This book represents the long-awaited synthesis of the studies constituting one of the landmark experiments in modern comparative psychology. Irene Maxine Pepperberg is Associate Professor of Ecology and Evolutionary Biology, Associate Professor of Psychology, and Affiliate in the Program in Neuroscience at the University of Arizona.

Amazon.com Review:
When Irene Pepperberg, a professor at the University of Arizona, says goodnight, she typically hears the reply 'Bye. I'm gonna go eat dinner. I'll see you tomorrow.' Though the response itself is not unusual, the source is, for it comes from Alex, a gray parrot, Pepperberg's main research subject for the past 22 years. That parrots can talk is well known; what Pepperberg set out to study was their cognitive abilities. By teaching the bird the meaning--not just the sound--of words in order to communicate, she hoped to discover how his brain worked. She exhaustively details her fascinating results in The Alex Studies.
Pepperberg bought Alex--a parrot of average intelligence and without lofty pedigree or training--from a pet store when he was 1. Since working with Pepperberg, he has developed a 100-word vocabulary and can identify 50 different objects, recognizing quantities up to six, distinguishing seven colors and five shapes, and understanding the difference between big and small, same and different, over and under. He can tell you, for instance, that corn is orange even if there is no corn in view, as well as correctly select the square object among various shapes and identify it verbally. What this all means, stresses Pepperberg, is that Alex is not merely parroting but actually thinking; he bases answers on reason rather than instinct or mimicry.
Though the anecdotes are rich and Alex makes a lively subject, this is principally a research paper relying on intricate details and a prodigious amount of data (the notes and references alone run to 79 pages). This is not light reading, particularly for the layperson. Still, The Alex Studies manages to be more than a valuable contribution to science, for in providing ample evidence of our similarities to other creatures, the book ultimately calls into question the concept of human supremacy over the animal kingdom. Pepperberg's stated goal is 'to provoke awareness in humans that animals have capacities that are far greater than we were once led to expect, and to remind us that all we need to examine these capacities are some enlightened research tools.' She has provided such tools in this seminal work. --Shawn Carkonen

I have followed Irene Pepperburg's articles on her African Grey Parrot, Alex, for years, both learning and teaching my own African Greys with her methods. I was so happy to see her write this book as her own personal tribute to Alex who was not just a lab specimen but a friend as well. Thank you, Irene. Alex will be missed by many.

I read Alex & Me very first and I'm glad I did. This 'studies' book is NOT for the lay person as it is very scientific and technical. I read one page and put it back on Amazon. Unless you want to duplicate these studies you probably will not enjoy this book.

Animals have magnificent powers of communication. I'm convinced of it. We humans just have not taken the time to ask them questions. All too often we treat all animals as livestock, here on earth as decorations or food. Again and again I've seen people make amazing communications with their pets, ones you wouldn't think pets were capable of -- because we have to change our thoughts about animals. We are the weak ones because we have cognition and communication skills but have not chosen to bring out the same skills in animals. For more on these kinds of ideas I would recommend Paws & Effect: The Healing Power of Dogs, which shows how amazing dogs can predict heart attacks and diagnose cancer. The book shows that probably all dogs can do these things -- we just haven't asked them. Animals are amazing.

This is a great book about how Alex came to be and how he became so smart. Dr Irene Pepperberg chose Alex as a young parrot and began teaching him language and to associate words with objects. Alex became very smart and could hold a pretty decent conversation. This book shows just how intelligent parrots are and they are more than just pets, they are our lifelong companions. The Alex Studies is an excellent read, I reccomend this book highly.

What can a bird learn? Irene Pepperberg set out to find out. As with children, the best way to assess what has been learnt is to ask. Primarily for that reason, she chose birds capable of forming human words. An African Grey parrot, who she dubbed Alex [Avian Learning EXperiment], became the subject of her investigations. Earlier efforts in laboratories were unsatisfactory. Why should Mynahs, reputedly excellent mimics, fail to learn speech in laboratory conditions? When in homes with several people providing input, they chatter endlessly, almost to distraction. The solution, Pepperberg decided, was the intense social environment. To that end, she developed a training method that produced astonishing results.
This book thoroughly documents the author's methods and results, providing a fascinating account of the cognitive abilities of at least one psittacine species, the Grey Parrot. Incorporating a technique she calls M/R - for Model/Rival, Pepperberg would "teach" an assistant what she wished Alex to learn. The bird observed this, then was encouraged to emulate the learning experience. This meant the bird had to understand what was to be learned and use its innate abilities to achieve it. Speech was the very first lessons, but things moved well beyond simple words quickly. Shapes, colours and materials were the subsequent level, with Alex discriminating among them both singly and in groupings. The object was to understand what Alex could comprehend and act on. Alex also learned to differentiate - "larger", or "different" or, most significantly for a bird - "abscence". He could note when something was missing, naming the missing object. The method resulted in Alex's expressing his own needs and wants, even ending a training session by declaring he wished to quit.
Pepperberg's research findings are in direct contradiction to past scientific efforts. The book is therefore richly detailed with the methods used and was information was obtained. There are photographs of test object layouts, even stills from X-ray videos of how Alex forms his speech. She is clearly challenging the received wisdom of established opinion. She's careful to avoid terms like "consciousness" or even "intelligence", although the latter comes in for some discusion late in the book. She finds only one example of Alex's communication she thinks can be deemed "creative". Much more important, in her view, is that we need to understand previously under-evaluated cognitive capabilities in parrots. They are a long-lived and social species, conditions which lead to interaction among individuals and reinforced learning. Social interaction, combined with carefully devised teaching methods are essential to proper learning, whether with children, other primates or psittacines. The capacity is there, and we need to recognise it. The Alex studies clearly demonstrate that at least these psittacines are capable of far more than the simply mimicry we've long attributed to them. Human primacy in learning, once considered fundamental to our place in Nature, is clearly at an end.
Pepperberg's narrative is thoroughly detailed and supported by an equally thorough bibliography. The reading may be a bit of a slog for the novice reader. The citation method breaks up sentences, a common technique with ethography studies, but cumbersome to cope with. The method is in line with her concern for academic acceptance. She excuses the approach as not desiring "to overwhelm readers with facts and figures" [although there are still plenty of those] but to encourage an enlarged sensitivity to the abilities of non-human species. She has certainly accomplished that task, and admirably. [stephen a. haines - Ottawa, Canada]
