Those rooms look like torture rooms and then that music.
- allovernow 7y ago
  Honestly the choice of music could make this a response to an unusual stressor, but an expert could probably infer from posture and facial expression whether they are in distress.
  - dmix 7y ago
    Agreed, this is a lot of speculation from short clips by people who probably don't know what they are talking about or what conditions these animals were really in. But I have to say the article description: > He was subjected to periods of piano music with a repetitive bass note for 24 days. combined with the choice of music in the videos is just asking for the internet outrage machine to react.
mrtweetyhack 7y ago
That's not music and those actions could be coping mechanisms.

This is kinda disturbing. Animal experimentation that saves lives is being disrupted while this kind of thing, with no observable value, and clear detriment to the animal, persists? Sure, I am curious about animals and music, but this just seems to misrepresent both. Someone please explan how I am wrong and overreacting, since that is usually my rally cry in comments.
- ggm 7y ago
  What if understanding innate brain response to music helps inform brain science and cognition and in turn leads to better understanding of e.g. locked-in or coma patients? What if dancing helps improve the lives of animals held for scientific experimentation?

  Sometimes science involves learning things for which an immediate economic benefit is not apparent. It could very well be that a decade or two from now, our knowledge that animals brains universally react to rhythms is a useful datum in cracking some critical piece of knowledge about how brains work and, potentially, how to fix them. Or, alternately, it could turn out to be practically worthless. But we don't know, and knowing more things is almost always not worse than knowing fewer things. Also, your argument assumes a lot of things: 1.) animal experimentation is being disrupted, 2.) playing music for chimps is clearly detrimental to them, and 3.) the resources that went into this study (these particular chimps, these researchers, and their funding) could have gone into some specific but unidentified better study which did have an pre-observable value. If all of those things are true, which has definitely not been established, than I would grant that science is likely not being conducted in a way that is maximally efficient, but unless there's some hugely valuable experiment that is being overlooked for this, I don't see why you're disturbed.

    tho if there is one field that almost always results in nothing from random experimentation, it’s psychology.

    > Sometimes science involves learning things for which an immediate economic benefit is not apparent. Exactly. That's why I want to find out how you would react to being stimulated with a powerful current 5 minutes after you fell asleep. My thesis is that you wouldn't last long, but who knows what use could come from the experiment decades down the road? So instead of delaying, strap on those electrodes so we can make some progress up in this bitch. As you yourself said, knowing more things is almost always better than knowing fewer things.

You'd think they'd play them better music. Abstracted to the point of silliness.

This looks a lot like stereotypical behavior seen in many captive animals: https://en.wikipedia.org/wiki/Stereotypy_(non-human) https://en.wikipedia.org/wiki/Stereotypy_(non-human) FTA: "Many stereotypies can be induced by confinement; for example, cats pace in zoo cages.[11] Pregnant sows whose feed is restricted bite at their stalls' bars and chew without anything in their mouths.[12] In laboratory rats and mice, grooming is the most common activity other than sleep, and grooming stereotypies have been used to investigate several animal models of anxiety and depression.[13] Examples of stereotypical behaviours include pacing, rocking, swimming in circles, excessive sleeping, self-mutilation (including feather picking and excessive grooming), and mouthing cage bars."

  Yeah seriously. Imagine being locked up and loud music blasted at you. This isn't science, this is inhumane; imagine doing this to a human. Some things aren't worth knowing, considering the suffering it would take to learn.
  - djtriptych 7y ago
    I do think it's worth knowing why we dance.
    - thatcat 7y ago
      We dance to display fitness to mates and increase agility.
      - improbable22 7y ago
        But then why don't chimps dance? Or any other mammals really. I mean it seems clear that fitness display is a part of why we do it, but it can't be the whole reason.
        thatcat 7y ago
        Humans are the only mammal that uses distance running for hunting, resulting in different injuries than chimps, etc.

I spent a lot of time with Chimps in West Africa, getting to play with, carry and interact with them a couple of different times [1] Sitting with a fully-grown chimp on your lap with her face inches from yours while she grooms your beard is a very, very special experience. It's impossible to spent more than 10 minutes with them and not clearly see they are us and we are them. Their facial expressions, they happiness, their playfulness, their grief. Everything about them is like looking in a mirror, or watching a ~5 year old child play. Absolutely amazing. I have no doubt they would dance to music, and do a lot more things that show intelligence and higher thinking.

  I am certain we are them. Emotions and feelings are entirely an animal trait in us. Whether they are us is a more complicated question. What are their language and reasoning abilities? Apparently no animals ask questions, even after being “asked”. Seems that questioning and reasoning is what makes us human (sapient). I’m pointing this out because most people would say that it’s the emotions and feelings that distinguish us. That’s not the case.
  - simonh 7y ago
    I think it’s clear mammals and certainly primates exhibit emotional behaviour, in which case it’s clear our common ancestors must have exhibited such behaviour. The question is, is our experience of those emotions similar? I see no reason to doubt it. The question boils down to whether animals have a sense of self and experience a ‘first person’ view of the world. Experimental evidence suggests that several species, including primates do have a sense of self and there’s so evidence they also have a theory of mind [0]. It has been argued that a first person experience of the world is not required for advanced reasoning, language, etc in discussions of AI. That may be the case. In which case our first person experience may be independent of and pre-date our advanced reasoning skills. Even if it is required for reasoning ability that’s also consistent with us having it first. I just don’t see any reason to see them as necessary for each other either way. Finally, if the experience of the world and the basis of our responses to stimulus did undergo such a dramatic shift at some point, that seems like an extremely dangerous transition. An awful lot could go wrong with that, and in fact everything about such a shift would have to go extraordinarily well or the result would be catastrophic failure. All evolutionary transitions have to progress through stages that are each viable at every step. Huge leaps don’t happen, because the odds of success are impossibly low. It seems more likely to me that our emotional responses are similar to closely related species, because the neurological basis for them, and mental experience of them are also similar. Otherwise we need to figure out why a radically different mental experience evolved, and why, and how come it leads to no appreciable difference in emotional behaviour.

This is not music, but machine noise. And the animal moves in a rhythm unrelated to said noise. So I'd guess it's a sign of stress.
- a3n 7y ago
  I had the same thought. If I was subject to that noise for long enough I'd be rocking back and forth too. But, maybe that's not a sign of stress in chimps.
- pmoriarty 7y ago
  There is a genre of music called "noise", which is much like what the term sounds like. I remember coming home from a noise concert with a friend one day, and going down in to the subway, where there was a construction worker hammering away with a jackhammer. My friend and I found ourselves really enjoying it, and appreciatively nodded our heads to the beat. Lots of experimental and avant garde music is also frequently described as "noise" to people who aren't fans of it. Back at the dawn of the rock-and-roll genre and of jazz, people to whom these were new types of music also frequently characterized them as "just noise". I've heard the "that's not music" accusation being thrown at heavy metal and dissonant traditional Japanese music. That's not to say that chimpanzees must be fans of what was played to them, but the realm of music is much wider than most people that listen only to mainstream music appreciate.
  - mc32 7y ago
    I don't think that is a fair comparison/conclusion because you could also then argue that torture is pleasurable because we can find some people who feel that (at least a subset of torture) is pleasurable to them and therefore people who feel that torture is torture should learn to enjoy it as pleasure.
    - nsomaru 7y ago
      I think this points to the conclusion that you can literally enjoy anything if you contact it repeatedly with the right attitude.
trhway 7y ago
upon hearing some very rhythmic joyfull children music our dog when he was younger would jump on his feet and start kind of happily bouncing around, not just like running or jumping, more like rhythmically walking and turning while swinging body (very profoundly shifting weight between the paws of different sides) from side to side - it was as close to dancing as i suppose a dog untrained to dance can get, reminded a lot how very young children do it.
stephc_int13 7y ago
I checked the video and it sounds like torture to my hears. I wouldn't be surprised if they used the same tracks in Guantanamo...
amelius 7y ago
They never tested this before??
stewbrew 7y ago
"researchers played music to a group of chimps (three adult males and four females) and found that all of the chimps responded to the music by moving in dance-like ways—though the degree to which they danced varied greatly between them. [...] the chimps had different moves." So, we have 7 chimps that responded to an unusual sound (we really don't want to call that danceable music) from a source unknown to them in 7 different ways, and we have n researchers that were set out to interpret that as dance? And these researchers can make a living out of that and get published? p.s. I skimmed through the original article. It looks like science and this might even be a standard approach in this field (I don't know) but ... I cannot describe what I think of it.
- nikkwong 7y ago
  No kidding. This is a quintessential example of what is wrong in research. If you were to just read the paper you’d definitely come to the conclusion that the researchers want to make—that monkeys dance much like we do. Then you go and watch the video and find their conclusion...biased at the least. The instances in which this type of tomfoolery becomes truly malignant are the ones in which it’s less obvious. I.e researchers have hidden or hashed the original data and then published something that we can’t unscramble. I’m literally expecting to hear “everybody dance now” and end up hearing that charade instead. Lol.
  - ChuckMcM 7y ago
    Which is the really super awesome part of science. You find chimps that don't care when they hear music. You find chimps that make "dance like moves" when you play atonal non-syncopated note structures, you find chimps that make "dance like moves" when you play dialog. Then you go through and plot your results and you show that this particular study isn't really indicative of what is going on. My mother once lamented "How can they call that science? That isn't a valid way to test that statement." And I reminded her, publishing a paper isn't "science", forming a hypothesis and a set of experiments to prove or disprove that hypothesis, and then having others test your hypothesis in different ways and getting the same result. THAT is the scientific process. And after that happens you know something new and you can demonstrate it on demand, each time, every time, because you know what is going on.
firefoxd 7y ago
I haven't gone through all the research to fully understand the argument, but I watched the videos. Not convincing at all. If I were to make this claim, I'd show a chimpanzee at rest in the video, without any music, then start the music. And actual music, not this loud machinery that would make me sway left and right due to stress. Edit: not saying that chimps don't dance. Just that this is a very unusual setting.
hetspookjee 7y ago
The cages these animals are in looks horrendous and I think that any result that comes forward from such an experiment is biased at the very least. With the current state of technologyouldnt it be more possible to set up these experiments in their natural habitat? I'm thinking about a large amount of cameras that track the animals. At least the animals have a better habitat to live in because this view is abhorrent, and so far I've het to see an animal experimention plant that has a beter environment for animals. And in another light, how valuable is this kind of research where an extremely intelligent animal is out in solitary confinement and is given tests? There is so much information lost in the process due to interpretation and external factors. Let alone the hilariously low N size. Also horses, elephants and a large swath or other animals have been shown to appreciate music. I don't even get why this party got funded to study an even higher echelon animal of which it is very reasonable to assume it is able to dance.
dr_dshiv 7y ago
What is truly bizarre is how rare rhythmic entrainment seems to be [1]. Powered oscillators naturally entrain to one another, like the synchronization of metronomes. Since neurons are powered oscillators, it would seem that even simple animals would be able to move to a beat. Yet, we are unable to train mice, birds or primates to tap out the beat to a song! My theory is that all animals have extensive defense mechanisms to prevent motor entrainment to external stimuli, since that would make one very vulnerable. Therefore, they only exhibit entrainment during ritualized mating, etc. Humans have evolved to let down our defenses, on occasion, to support social entrainment. Yet, it is still really hard to dance or appreciate music when we are uncomfortable or stressed. One test of this theory would involve giving animals drugs like mdma to see if it helps them loosen up and appreciate the beat. It works with people, after all. But I suppose proposals like that would be taboo science. Or, perhaps it would be unethical to give chimps mdma?

  > to support social entrainment Possibly. I can't find the write-up of this, but there's a nice idea that this may have another purpose: Dancing as a group might be a way to fool savannah predators that your tribe is one large animal, not individual hairless tasty meals.

  >>> My theory is that all animals have extensive defense mechanisms to prevent motor entrainment to external stimuli, since that would make one very vulnerable. Therefore, they only exhibit entrainment during ritualized mating, etc. Wow, seems very reasonable! It made mi think about it in a bit different way: as other animals are thought as "following instinct" and "closer to nature" maybe this inhibition systems are way more advanced in humans than in other animals. It would make explaining dance harder, but would fit great to big literary topos "men vs nature". Is it completely your theory or was it inspired by something that you could recommend?
