In the fall of 2007, as the weather started to get cold, squatters moved into my attic and into the warm crawlspace under my house. I didn't notice them, because they were invisible, didn't make a sound and were very discreet. At least, that's how it seemed to me, after I found out they were there. But from Bow's perspective, none of this was true. According to Bow, they were loud and annoying, and he couldn't stand their wild orgies.

The squatters in my attic were field mice.


The New Quarters and the Scary Drains

In the summer of 2007, our living arrangements changed drastically. The sun room was converted into a series of pens, with long corridors leading from the indoors to the outdoors, and a single corridor feeding into the "potty room", equipped with a shiny metal prison style toilet that Bow was to use.

Each of the two indoor pens had a metal drain in the middle, and the floor had a slight incline to help water drain easily. Gone were our beautiful wooden floors and gone was Bow's freedom to roam from room to room throughout the house.

New interns learned to dread the potty corridor, because in the bathroom there was toilet paper! It was in the potty corridor that Bow did his best to haze new recruits. Give Bow a long corridor and a roll of toilet paper, plus a new intern to terrorize, and we at once experienced complete pandemonium.

On the other hand, if I escorted him there, he held onto my hand or rode on my back and was a complete angel, doing his duty and indicating by an elegant twist of the wrist that he was done, and it was time for me to get  some toilet paper to wipe him with.

I had originally thought that it would be fine if we didn't always use the metal potty. If Bow wanted to pee directly into the drains, I had no objection. It would also save wear and tear on the new interns and by-pass the inherent drama of the potty corridor. But no! There was no way Bow would go anywhere near those scary drains.

At first, Bow was completely inarticulate about his unreasonable fears. He would just gingerly swat at the drain with one hand, keeping the rest of his body at a great distance, lest the drain, or something in the drain, retaliate against him.

After Bow became literate, I asked him why he was afraid of the drains. His answer: "There are animals there."

"Animals?" I repeated. "What kind of animals?"

"Bad animals."

"How do you know they are bad?"

"They want to eat me."

"Bow, come on! Why  do they want to eat you?"

"Because they're bad."

Needless to say, I didn't believe him. After all, he couldn't produce a single shred of evidence to back up his story.  


Bow

Humoring Others and Being Humored in Return

As summer changed to fall, Bow's complaints about the animals under the floor became more frequent and frantic. There were times when he would race around in circles and scream and when I asked him what the problem was, he insisted that it was "animals." There were animals under the floor. There were animals over the ceiling. I didn't see, hear or experience anything that would corroborate Bow's allegations, and what's more, he was a notorious liar.

Very soon after he began spelling words, Bow told me there was a fire in the kitchen. It was a full sentence, in Hebrew, very grammatical, and like any person interested in the truth, I went to investigate. There was no fire.

This happened a few more times before Bow admitted that he only said that because he was hoping I would take him to the kitchen.

On another occasion, Bow told me he saw a mouse in the kitchen. I went to look. I didn't see a mouse, but Bow kept insisting there was one. "So what do you want to do about it?" I asked him, a little weary of all these lies.

"I want to go catch the mouse."

Aha. So it was another excuse to go to the kitchen.

One day Bow said: "Stop feeding me in the pens."

"Why? Where do you want me to feed you?"

"In the kitchen."

It seemed like a very clear pattern. Bow wanted to go to the kitchen. He would say anything if he thought it would get him there.

So, when Bow kept mentioning those animals, I didn't believe him. But since there was no reasoning with him about it, I started to humor him. Instead of arguing that there weren't any animals, I would say things like: "Never mind those animals, what would you like to have for lunch?"

During the same period, as I was having trouble producing any solid proof that it was really Bow who was pointing at the letters, I noticed that a number of people with whom I had regular phone conversations were now avoiding the topic of Bow. If I told them Bow had said something, they just didn't react. They didn't get excited. They would change the subject. They never tried to argue me out of it, but they were amazingly unresponsive to what I had to say.

At first, I didn't know why those conversations were so odd. Nobody had said anything bad to me, but after I hung up I began to feel very depressed. The normal give and take of the conversation just wasn't there. Why weren't they more excited to hear what Bow had had to say. Then it dawned on me: I was being humored.

They didn't believe Bow was spelling at all. I had no proof, and, of course, I knew I had no proof, but I thought what was happening was interesting even without the proof.

After all, knowing that something is true and being able to prove it to someone else are two separate issues. Not being able to prove something is not the same as proving that it's not true.

How could they just assume that I was wrong? But I was doing the same thing to Bow. He kept insisting there were animals, and just because I couldn't hear them, I assumed they weren't there.


It's hard to keep an open mind

It's hard for anyone to keep a completely open mind. We think we know so much about the world already, that any fact that threatens to overturn some of that knowledge is often rejected out of hand. For any proposition X about a real world state, most of us, (myself included), have one of four states of belief:

  1. We believe X is true.
  2. We believe X is false.
  3. We believe X is not a meaningful proposition, so its truth or falsity is logically unascertainable.
  4. We feel X is so insignificant, that any implications to be drawn from it are also unimportant. In such an event, we are willing to concede that we don't know, because we don't care.

People very rarely feel that they don't know whether something is true when it is both meaningful and significant. Why? Because every significant, meaningful proposition about the real world has implications for the truth or falsity of many other significant propositions. There are no facts in a vacuum. We have states of belief about those other propositions, and we would have to change them, if we changed our mind about X.

Whether we can prove Proposition X to be true (or false) is a separate question from whether we believe it to be true or false.

You may have witnessed an event. You may be the sole witness. You believe the evidence of your senses. Somebody else may or may not believe you. You may realize that besides your own testimony, you can produce no other proof. In such a situation, you believe you know the tuth or falsity of the proposition, but you have no proof.

In the case of the mice, Bow's sensory acuity was better than mine. It took some time before evidence that I could take cognizance of could be found. But Bow was right about the mice, even when he could not prove it to my satisfaction. What he claimed was no less true before I noticed the evidence that supported his claim.

It is hard to keep an open mind, because living in the real word requires us to formulate a working hypothesis about many different things. We can't wait until we have absolute, irrefutable proof of the truth or falsity of a proposition until we formulate a belief about it. The facts of reality are a matter of life and death. Being indecisive can cost us.

Corroborating Evidence

One day, Bow became especially frantic and was screaming like crazy. When I asked him what was the matter, he spelled out "Animals Pee". It was in Hebrew, as usual, but this time it wasn't a well-formed sentence, It was just the word "animals" followed by the word for "pee."

"Do you need to pee?" I asked him.

"No. Animals pee." He kept screaming while he spelled.

I ignored the animal part of it, but I thought maybe he needed to pee, even though he denied it. I had learned to my peril that it was not a good idea to ignore the word "pee." So I dragged Bow down the corridor to the metal toilet and made him sit there, but he wouldn't pee.

As we were making our way back to the pen, I noticed some drops of moisture on the cement floor of the adjoining pen, the one we hadn't occupied. Bringing Bow back to his pen, I peered through the glass at the drops on the other side. Nobody had been there. Bow couldn't have made those drops. Where had they come from?

I turned to Bow: "Is that what you meant?"

He answered: "Yes. Pee of animals."

"Where did it come from?" I asked Bow.

"Animals on the ceiling," he spelled..

I went over to other side. There were definitely drops on the cement. They did indeed seem to have fallen from above, rather than seeping from below. Bow's version of the truth was suddenly looking a lot more believable.  

"There's a man whose job it is to catch mice," I told Bow. "Do you want me to call him?"  

"Yes. Right away!"

"Bow, in order to call the man right away, I would have to leave the pen. Are you giving me permission to leave?"

"Yes."

This was a very big deal. Bow hates to be left alone.

Why Didn't they Just Let them Go?

I did not go into the details of what an exterminator really does, because I didn't think Bow needed to know that. He had enough other things to worry about. What I didn't realize at the time was that Bow would have to know. There was no way to keep it from him.

Calling the exterminator and getting him to actually come are two different things. We live out in the country. Repair people and service providers come at their convenience, not ours. I called right away, but it was a few days later when the exterminator finally arrived.

Meanwhile, we were expecting a visit from another primatologist, and Bow continued to worry about the "animals" in our midst. When our guest did not arrive as planned, Bow was very concerned. I told him that the delay was due to car trouble; Bow wanted to know if there were animals in the car who had caused it to stop running. During that period, Bow was inclined to attribute any mechanical failure to animal infestation.

The other primatologist told me that Bow's drain phobia was quite common among chimpanzees and bonobos. It was also pointed out to me that chimpanzee sensory acuity was much better than human, and that Bow could hear things well outside my hearing range, and was probably aware of things that were happening within a radius of miles from our house.

This explained why all this time Bow had insisted on telling me what was going on in the house across the road. He had definite opinions about the characters of all the residents. He tended to identify with the points of view of the children and the dogs. I had taken all of this with a grain of salt, because after all, he did lie.

The exterminator arrived when we still had our guest with us, and Bow was happy about the whole thing. It wasn't until the next day that he began to complain that the mice were screaming.

"Why are they screaming?" he asked me frantically.

"I can't hear them," I said.

"Why can't you hear them! They're dying! It's too bad that they're dying," he told me. "Why did they have to kill them? Why couldn't they just let them go?"

The next few days were very hard. Bow became more and more agitated. If I thought he had been frantic before, he was much worse now. He was distraught. He ran around in circles and screamed and tried to tear his hair out. It was impossible to get him to concentrate on anything. According to Bow, every day, just as one batch on mice had finished dying, new mice would come in, eat the bait, and scream in agony. "This is unbearable," Bow spelled out in Hebrew.

At first, I was shocked that he knew, but I hoped it would all end soon, and we could get back to normal. However, there seemed to be new waves of mice every day or so, and more screaming, according to Bow, and it became a never ending saga of horror. Finally, I asked Bow if he wanted me to call the exterminator back and ask him to put a stop to the dying. He said he did.

I never fully explained it to the exterminator why, but I asked him to remove all remaining poison packets from the attic and the crawlspace.

Mice, Cows and Elephants -- A hearing test!

Things went back to normal, more or less, after the poison was removed. Bow was not frantic, most of the time, but every once in a while he complained about all the noise that the mice were making.

"I can't hear it," I told him.

"Why can't you hear?" he asked.

"My ears aren't so good."

"Why are your ears not so good?"

I had to think how to answer that. "I'm not young anymore, so I don't hear as well as I did when I was a child."

"But Sword also doesn't hear the mice."

"Yes, well, I guess human ears aren't as good as chimp ears."

Bow needed some time to process this information. On a different occasion, he said: "I hear a cow. Does Mommy hear the cow?"

I answered: "Yes. I hear the cow. It goes moo." I tried to imitate the cow's lowing. 

"Yes," he agreed.

We had established that we could both hear a cow out in the neighbor's field, but only Bow could hear the mice in our attic and crawlspace. This was some information about our respective hearing ranges, but it was not enough. Now, if we only had an elephant in the area, we could establish the lower bound!

Not wanting to limit myself to this method of empirical testing, I looked up some statistics on chimpanzee and human hearing.

Comparative Hearing of chimpanzees and humans

A mismatch in speed and a mismatch in frequency

Until the spring of 2007, I had not been aware that chimpanzees process information at a much higher rate than humans. Until the fall of 2007, I had no inkling of the difference in our hearing ranges.

It's so easy to think of a chimpanzee as being a hairier, slower, less advanced version of ourselves. Even those of us who have the most "progressive" attitude can easily fall into this trap. Many animal rights activisits see themselves as the guardians of chimpanzees, who they imagine to be somewhat underprivileged, lesser abled versions of ourselves. Nothing could be further from the truth.

Chimpanzees and humans are different, but the differences are not what you would expect. Chimpanzees are stronger, healthier, and faster than we are. Flash information on the screen for a split second and they will process it before you've had a chance to see that there was anything there.

The higher speed of processing is not completely unrelated to their ability to hear at higher frequencies than we can. Human hearing ranges between twenty to 17,800 HZ, with our best hearing occurring somewhere in the vicinity of 4,000 Hz. We don't know what the lower bound of chimpanzee hearing is. Not enough research has been done. However, it has been established that chimpanzees can hear as high as 28,500 Hz, and that their best hearing is around 8,000 Hz. Best hearing means that one is able to pick out a sound in a particular frequency even if the sound is very faint.

On the face of it, the differences between the human upper bound and the chimpanzee upper bound for hearing may not seem like much. Other primates hear even higher pitched noises than chimpanzees do. (A lemur can hear sounds at 58,000 Hz.) But if you take into account how much softer a high pitched noise can be and still be audible to a chimpanzee, then you see that there is a significant difference.

Maybe I could have heard some of the sounds the mice were making, if they were right there in front of me. Bow could hear them through the insulation in the attic.And it really bothered him!

 

What the mice were doing and why it bothered Bow

After the poison was taken away, Bow relaxed and was able to concentrate better. However, he let me know that there still were mice and that they were still making a lot of noise. Every once in a while he would become very frustrated, and he complained: "I want them to stop making noise."

One day, I asked him why it bothered him so much. He wrote out: "Because I need to also."

"What? You need what?"

"A girl friend."

This confused me. In Hebrew, the world for girl friend is just the word "friend" in the feminine. It's ambiguous. Bow already had lots of female friends. Most of the interns were women.

"What kind of girl friend?"

"An ape girl friend."

That's when I realized that the mice were bothering Bow because they were having loud, raucous sex.

Realizing How Little We Know

The more time I spend with Bow, the more I realize I don't know about the world around me, and about humans and chimpanzees in particular. If Bow were just a slower version of a human, proving what he can do would be easy. It's because he is faster and better able than I am to observe the world we live in that proof is so much harder to come by.

Some people ask, if chimpanzees are so smart that they can understand human language, why don't chimps in the wild have language, too? My answer is: what makes you think that they don't?

If human observers cannot process it, that doesn't necessarily mean that it's not there. I don't hear the mice, but that doesn't mean they're not here.

This fall, when the weather started to turn cold, Bow turned to me and spelled: "Let's not do anything about the mice this time."

I agreed.

I absolutely loved this hub and I didn't even see the link until just now, thanks! These are the kinds of interesting facts that I think many are wanting to learn about the world beyond humans, and our fellow creatures on this planet. We all have so much to learn, if only we open our minds to the endless possibilities.

I would humour you too if you had no proof. How come you can't prove to your friends that Bow can communicate? Surely he must be creating some kind of signal in the physical world that you can process and interpret and document. Poor horny Bow. He is complex enough that he might not like a blind date with some random female chimp. He might find her shallow or of a different philosophical persuasion.

Hot Dorkage, but you're not humoring me! You're asking questions, which is completely different. I would rather deal with a healthy skeptic any day rather than somebody who has already made up his mind.

There is evidence. If you watch the 2007 DVD, you can see Bow pointing by himself, but by and large, most of the time, he hold ours hands in order to make us notice what letters he selects. You have to read the entire series on Bow and watch the videos, in order to form a preliminary opinion. Then, hopefully, a healthy skeptic will propose useful tests.

The short answer is, if he is holding your hand, you know that he pointed and you didn't manipulate him. If you are an onlooker, you can't tell. So if I watch Eden with Bow, just like you, I have to either believe Eden that she didn't choose the letters, or disbelieve her. He has written with more than one person, and he has written alone, but he doesn't answer out of context questions, and so we have no "objective" fool proof, non-anecdotal evidence.

Bow won't bother to point, if he thinks we won't see.

Anyway, read the whole series, including the comments, and watch the DVDs, to get an idea of the problem.

Ajcor, thanks for your comment. My daughter is named Sword and so I named Bow after an even more ancient weapon. The word "QST" in Hebrew can mean either bow as in "bow and arrow" or bow as in "rainbow".

Aya, I'm so fascinated by your hubs about Bow, and I have shown them to my children. My 10 year old is so impressed that he would really like a chimp brother too. In fact he asked me to e-mail you to find out how we could get one! Poor old Bow, living with the frustration of hearing things that no-one else can hear, and being (at least initially) disbelieved. Having Bow must be the experience of a life-time. A lot of hard work, but huge rewards.

Hi Aya,

I'm not sure about the legal side of things here in the UK, but in any case, having seen the way things went with the hamster, I'm not planning on organising a chimp brother any time soon! It's a lovely idea though, and I imagine Sword must love her unusual sibling!

Aya Katz profile image

Aya Katz  says:

Amanda, adopting a chimp is a lifetime commitment, so you are wise not to jump into it lightly. Sword and Bow love each other, but like most siblings, they also experience rivalry and competition. The things they say to one another are not always as nice as I would like. However, it's all part of the normal ups and downs of the sibling relationship.

I love reading about you Sword and Bow in your Hubs. I have to say after spending weeks in a house that was infested with mice I have every sympathy. At least I had the option of lying to my kids and telling them the mice were just being caught and released. On the sibling front my daughter thinks a chimp brother might have better manners than her human brother

Ida-May, thanks! I don't know about the comparison in terms of manners that your daughter made. I guess I'd have to see her brother in action. Anyway, it takes two to quarrel. Neither one of my kids is completely blameless. On the other hand, they can each be very considerate of the other, when the spirit moves them. ;->

Wonderful information about Bow as always. It never fails to amaze me how intelligent chimps (and all the great apes) are !!

This is the first time I've come across one of your hubs about Bow. I must say, b/efore you said Bow was a chimp, I was confused. Thought maybe the new digs were for children (not a bad idea).

But Seriously, totally fascinating. I knew a show business chimp once named Skippy. He was on Letterman a lot many years ago, including the "chimp cam" if anyone remembers. I knew his owner/trainer. Skippy was funny and smart, but he lived in a New York apartment, not enough room for a chimp. He eventually got mean and went to live at a chimpanzee retirement park in Florida.

That's quite an experience raising one, judging by your writing. I have no trouble believing Bow can communicate. So did he get a girlfriend? That would suck having to listen to that non-stop orgy going on upstairs if you needed some companionship yourself.

Thanks for a most interesting hub! Can't wait to read the rest!

Aya Katz profile image

Aya Katz  says:

Misty, thanks! We're only just beginning to know the depth of intelligence that all the great apes are capable of.

Christopher Reilly, thanks for your comment. How old is Skippy now? Is his trainer still in touch with him? A New York apartment is probably not the best place to raise a chimpanzee. Sometimes we have to be flexible about changing the living arrangement, rather than institutionalizing the ape. Maintaining long term relationships is very important.

Bow still doesn't have a girl friend, but we're working on it. I am hoping to invite a female chimp guest to his next birthday party.

Ms. Katz,

I read in another post that you suggested Bow's reactions were too quick for the observer to notice so he began using your hand most often as a guide. Have you ever considered the Clever Hans Effect? That maybe there are unconscious clues that you give to lead him to the correct responses? Maybe to help skeptics you could blindfold yourself while he guides your hand and videotape his answers, or have someone else behind you watching what he does? and mixing up the responses so you don't know where they are.

Aya Katz profile image

Aya Katz  says:
11 months ago

Vida, thanks for your comment. Yes, of course, I've heard of the Clever Hans effect. No one working in ape language studies can have failed to hear about it. There was a big conference about this right about the time that Herbert Terrace denounced Nim Chimpsky.

The idea of using blindfolds (or opaque glasses) has been brought up many times. It won't work, because Bow will not spell for someone who can't see. That was the whole reason he started using our hands -- because we couldn't see what he wrote. (The problem wasn't visual obstruction, but the effect was the same.)

Daniel J. Povinelli has written a book suggesting that young chimpanzees don't know about seeing -- that they will gesture at someone who has his eyes covered -- but my experience with Bow has been quite the opposite. He knows all about seeing -- or rather, perceiving.

We've tried other things, though. We have someone ask him a question that Bow knows the answer to (what' in the box? for example), and the questioner doesn't know the answer. We've had mixed results on that. Nothing conclusive, because Bow does not cooperate with tests.

It sounds bad, but it doesn't prove anything, one way or the other.

Aya - your hubs about Bow are so gripping and so touching as well. How on earth can't people see that he can communicate - and so well too!

A little tip that might work where the mice are concerned - a drop of peppermint essential oil on a cottonball. A few of these scattered in the attic and maybe in holes in the garden tend to keep field mice away. That way, you don't have to exterminate them and upset Bow.

Aya, as others have noted, this is fascinating! If people don't believe that Bow can communicate it's because they don't want to. I had a research methods instructor who was fond of reminding us that you can't ever really prove anything, the best you can do is establish an empirical regularity, and your stories about Bow remind me of that. Fortunately, he has your voice, and your daughter's, and your interns', to share his story with others, and hopefully you'll continue to find new ways to break down barriers of disbelief.

Thanks for another great read! I'm amazed at how much I find myself caring for Bow and sympathizing with him in your stories. It was also interesting to see how much he came to empathize with the mice; no longer seeing them as enemies to be feared when he realized they were capable of experiencing such pain. It seems chimps can be more "humanitarian" than humans in that regard.

Aya Katz  says:

MelissaG, thanks for the support and encouragement! Yes, your instructor was right. We can never prove that an empirical claim is true with absolute rigor, we can only establish facts that tend to support a claim.

I'm not sure tha Bow has more empathy than we do, it's just that he could not help but feel for the mice, when he had to hear their death screams. If we could all hear what he can, maybe we would act differently, too.

Aya- I have one question for you: How much of Bow's intelligence is natural and how much of it is due to the training that you have imparted? I know chimps are intelligent but surely your training must have a great deal of influence in Bow's superior communication and intelligence. Another excellent hub by a great primatologist.

Aya Katz profile image

Aya Katz  says:

Countrywomen, thanks for stopping by again. It's a good question that you pose, but I honestly don't know the full answer. Bow is very intelligent. How much of that intelligence is due to nature and how much to nurture is difficult to determine.

I would like to point out, though, that "training" is probably the wrong word for Bow's upbringing and education. He is very resistant to anything that smacks of "training". He won't do anything for a reward. When he finally did start to communicate spontaneously using the lexigrams and then the letters, it was because he chose to. It was his timetable, not ours. 

I was expecting Bow to start "talking" (by using lexigrams) at the age of three. However, it was not until he was over five that he had the breakthrough. Reading the literature about chimpanzees in the wild, I noticed an article about how young chimps learn to crack nuts. The girls stay close to their mother and learn by imitating, so they are already learning how by thirty-six months of age. However, the boys are much more independent and hyperactive, and they don't settle down to learn how until about two years later. This is so consistent with what I experienced with Bow!

Every child has a different developmental timetable. I believe Bow was following his own. My hunch is that Bow is not more or less intelligent than the average male chimp his age. The only difference is that I provided a language rich environment. But we can't know for sure without much more statistical data on other chimps placed in similar situations.

Hi Dr. Katz, this is your former intern Allie! I was just getting up to speed on Bow and it made me miss him all the more. I am just pondering your dilemna with the speed in which Bow points and his preference for using the researchers hand to point with. I remember this scenario well and the challenges it presents, but I would love to see you find a way to capture his responses without the researchers hand. It's been a while since I've worked with him, but I was wondering if you might be able to find a way to convey the term "slower" or "slow down" to him, perhaps through play, so that the researcher could refuse her hand and insist on Bow slowing down to communicate if he wished to continue with the conversation. You might even be able to build upon your prior, above mentioned conversation with him about the capabilities of human hearing versus chimp hearing and relate it to visual processing.

I am thrilled to see that Bow and the project are doing so well. Please give he and Sword my love.

Hi, Allie. Nice to hear from you again!

Bow can slow down, but when he does, he points at single letters and doesn't spell out words. I think that it's very hard to slow down and still talk, because the rate at which we talk (or write) is the rate at which we process information. Here's an experiment you might try yourself: try to talk very slowly, making each sound separate. You'll see that it makes it hard for you to remember what you were trying to say.

We are hoping that using a touchscreen computer, Bow can point by himself at his own rate of speed, and we can hear what he said because the computer will read it out for us. This project is currently in the works.
