I recently presented an hour-long lecture to veterinary students on the cognitive and communicative abilities<\/a> of African grey parrots<\/a>. Given that I had only about 45 minutes to present the material (so as to leave time for questions) and lots to say, I organized the talk as I often do these days: I provided very little background and immediately went into the descriptions of the various current studies in my laboratory.<\/p>\n

I wasn\u2019t thinking about the fact that many of these young adults, although familiar with my work in general, had never read my journal articles nor had previously heard me speak. So when one of them asked about how I had actually trained<\/em> Alex, Griffin, and now Athena, to use English speech meaningfully, I was momentarily surprised. Then I realized that it had actually been quite some time since I had described my techniques in talks, and even in professional papers, preferring just to refer to earlier publications. As a consequence I thought I would take this opportunity to provide this information, along with a bit of background.<\/p>\n

Training Referential Communication<\/h3>\n

In the 1970s, after reviewing what was then known about vocal learning in parrots (actually, not very much at the time), language acquisition in children, and psychological constructs of social learning in humans, I formulated a type of instruction, termed the model\/rival <\/em>(M\/R) system. The approach efficiently teaches a parrot both how to speak and how to use its speech appropriately. It is based on methods developed by Todt (1975) and Bandura (1971), and it uses three-way social<\/em> interactions among two humans and a parrot, as a way to demonstrate the vocal behavior that is to be learned (Pepperberg, 1981; see photos).<\/p>\n

The parrot observes two humans handling and speaking about one or more items and how these individuals interact with each other. As the parrot watches and listens, one trainer presents objects and queries the other trainer about these items, with such expressions as \u201cWhat\u2019s here?,\u201d \u201cWhat color?,\u201d giving praise and transferring the named item to the human partner as a reward for correct answers. Incorrect responses are punished by scolding and by temporarily removing items from sight.<\/p>\n

Thus the second human serves both as a model for the parrot\u2019s responses and its rival for the trainer\u2019s attention, and also illustrates the consequences of errors. The model must try again or talk more clearly if the response was deliberately made incorrectly or garbled; that is, the model is subject to what we call the \u201cprocess of corrective feedback\u201d and the bird observes this process in action. The parrot is also included in the interactions: it is queried and rewarded for successive approximations to correct responses, and training is adjusted how well it is performing. If a bird is inattentive or its accuracy regresses, trainers threaten to leave.<\/p>\n

Unlike M\/R procedures others have used (Todt, 1975; see discussion in Pepperberg & Sherman, 2000), we interchange<\/em> roles of trainer and model, and include the parrot in interactions. This procedure shows that a questioner can also be a respondent, and demonstrates the specific effect of particular vocalizations. Role reversal also counteracts an earlier problem: birds whose trainers always maintained their respective roles responded only to the particular human questioner (Todt, 1975). With our technique, birds will respond to, interact with, and learn from any human.<\/p>\n

M\/R training uses only intrinsic reinforcers<\/em>: to have the closest possible link between labels or concepts to be learned and the appropriate vocalization, the reward for uttering \u201cX\u201d is access to X, the object to which the label or concept refers. Earlier unsuccessful attempts to teach birds to communicate with humans used extrinsic<\/em> rewards (Pepperberg, 1999): a single food was used that neither related to, nor varied with, the label or concept being taught. This procedure delayed label and concept acquisition by confusing the label of the targeted item or concept being trained with that of the food reward. We never used extrinsic rewards. Use of the label to request the item from the start also shows the bird that uttering labels is really useful.<\/p>\n

Later, when we had to train more complex tasks but had to use the same objects (e.g., for studies on labeling the number of items in a set), and the birds were no longer terribly interested in these objects, we trained them to use the phrase \u201cI want X\u201d and \u201cWanna go Y\u201d so that they could request whatever reward they wanted\u2014be it a piece of cashew, a tickle, or to return to their cage and an end the session.<\/p>\n

Although training a bird in this manner may seem to be something relevant only to scientific studies, it can be quite important in the daily life of a companion bird. One wouldn\u2019t accede to all of a parrot\u2019s requests (much like one wouldn\u2019t do so for a young child\u2014just so many cookies can be consumed in a given day!), but it seems only reasonable to give a parrot at least some control over its daily life. Think of how you would feel if absolutely every aspect of your day was decided by someone else.<\/p>\n

One of my friends actually asks her bird to choose among the acceptable fruits and veggies that can be put in its bowl each morning. We don\u2019t do that for our parrots, but we\u2019ve thought about it, as she claims that it cuts down on a lot of waste. We do, however, let our birds choose where to spend their free time, and to decide which toys they want as rewards. We find that our birds really seem to like having some choice in their lives.<\/p>\n
