To: primate-talk@primate.wisc.edu (from newtrogs@ionet.net [ Bob and/or Belle Ball Ingersoll ]) Here are a few comments and questions regarding Washoe and her display of "teaching" behavior or her ability to "teach" her infant sign based on my experience with her. Several things should be made clear here. Unless she has had a baby since she left Oklahoma, the last baby that she was with left Oklahoma with her and was almost one year old when she left. That infant would now be over 10, hardly an infant.That infant was named Loulis and he was acquired from Yerkes after Washoe's baby died (see Silent Partners for an account).When Washoe was in Oklahoma I was fortunate to be around during the time when Washoe was pregnant, on 2 occasions. Washoe has had, I believe, only 3 births. The first 2 infants were stillborn. Her third, Sequoyah, was born and lived for about one month. I believe that there exists a diary of data taken during the time that Sequoyah was alive, however, I have not seen this mentioned in the literature. Perhaps someone has a copy of it still. The second baby was born not long after I became a "chimp person," and during this time Washoe actually assigned a name sign to me. This is what happened. I was observing Washoe during a late evening during her second pregnancy. She was lying down on a bench in her cage, mostly resting but occasionally signing to me. I would respond when I knew what she was saying (I was new to signing and Washoe appeared to know that) During this interaction Washoe asked me "Name you"? and at that time I did not have a name sign so I shrugged my shoulders and signed "can't, "no" "name" "sign" then told her verbally what my name was, "Bob, Bob." She then looked at me and signed "Name you" and made this sign: The first two fingers of the right hand extended from the fist (like the boy scout hand signal), pulling the two fingers across the brow ridge. I later found out this is also the sign for black. Washoe never called me anything else after that, And from that point on when Washoe was asked my name or when it came up she always signed that sign. It's to bad that this was not caught on video as with most chimp signing, without hard evidence, we are reduced to stories like the one I just told. Anyway, back to the baby. As far as teaching her baby directly like a teacher to a student I only observed one incident that might be considered teaching. After the death of Sequoyah, her biological son, another infant slightly older was placed with Washoe. His name was Loulis, and he came from Yerkes. His name is a combination of the names of two Yerkes employees. Shortly after Loulis was placed with Washoe, there was an incident in which Washoe and Loulis were sitting across from one another. Both were very agitated, and at one point Washoe looked at and got Loulis's attention, then she signed "Hug" "Hug" "Hug" to Loulis, who then approached and jumped into the arms of Washoe. Several observers saw this and it was quite clear what had happened. Was this teaching? I don't know. That was the only time I know of where Washoe did what might be considered teaching. You must remember now that we could not sign to Washoe in the presence of the baby. That included prompting her to sign. What we had hoped was that Washoe would exibit some behavior that would look like teaching, ie. molding, like she was taught. If she did not sign directly to the infant we hoped that his being around her and her constantly signing (immersion), that he would pick sign up simply by observation. In order to facilitate this, the chimp Ally (the reported father of Sequoyah) was placed in the cage adjacent to Washoe and Loulis in hopes that Washoe and Ally would sign together, thus increasing the amount of sign that the baby was exposed to. Before Sequoyah was born we would sit with Washoe and Ally and sign with them in order to create a better signing environment, thus creating more sign between Ally and Washoe when the baby came. We theorized that if Washoe and Ally were at a high level of both proficiency and output of sign, the infant would see more signing. The original grant submission talked about the three chimps, Ally, Washoe and infant as a family. When Sequoyah died and Washoe was first moved from IPS to the OU campus and then to Washington, Ally remained at IPS. I do not know why Ally was excluded at that point. He remained behind, later was moved to LEMSIP, back to OU, and eventually became lost.(see Primate Talk, March 15, 1995 and Silent Partners by Eugene Linden). I understand and have read that Loulis uses many signs. Loulis may have learned those from Washoe in the traditional teacher-student relationship. However, I believe that it is much more likely that a signing context and the constant use of sign is more important than Washoe or any other signing chimp actually "teaching" another chimp to sign. After all, most human mothers don't actually teach babies, they immerse them in the language environment. In the wild I don't believe that you could say that for example the chimps that break the nuts with an anvil and stone are actually taught how to do that, they observe it and then start practicing until they are proficient at it. If language is made important in daily life it is usually picked up quickly by chimps in my experiance. If Washoe has exhibited more "teaching" behavior, I haven't seen any video or other hard evidence to indicate that. If that information is available, could someone make me aware of it, please? I would be the first to admit that it is possible that Washoe may have actually taught some sign to her infant, however, I believe it is far more likely that her infant learned sign because he was immersed in the signing envirorment. The chimps' ability to use and understand sign is not diminished to me because they did not learn it in a school-like setting. I would not expect that anyway. It is just as interesting to note that even though there is no evidence to speak of to indicate teaching, most chimps exposed to sign language pick some of it up. Many of the adult chimpanzees at the IPS, even though they did not participate directly in sign studies, somehow acquired sign. As you would expect the signs the non-signing chimps acquired included the sign for food and drink, also the sign for hurry and for come gimme. That is not unexpected, for Washoe lived in the same colony for many years with some of the chimps that ended up at Lemsip. I understand that several of them still sign at that lab. I believe that all chimps have the capacity to learn at least some sign. I hope this gives you some insight into what actually happens with signing chimpanzees.
