Octopuses Have No Personalities and Enjoy HDTV
Whiteox writes about an Australian researcher named Renata Pronk, who has discovered that octopuses prefer HDTV. She recruited 32 gloomy octopuses from the waters of Chowder Bay. Previously, researchers have reported little success when showing video to octopuses. Miss Pronk's insight was that the octopus eye is so refined that it might see standard PAL video, at 25 fps, as a series of stills. She tried HDTV (50 fps) and her subjects reacted to the videos of a crab, another octopus, or a swinging bottle on the end of a string. A further discovery is that octopuses show no trait of individual personalities, even though they exhibit a high level of intelligence. It would certainly be possible to quibble about the definition of "personality" employed, and whether Miss Pronk had successfully measured it.
...your standard geek.
What, too close to home? :)
Only Australians would be cruel enough to give Vegemite to poor defenseless octopi.
When I read that headline, I thought it applied to many of the people I know as well...
just remember that.

That is all.
I think that by understanding a creature as alien to us as an octopus, we're learning more about what is 'intelligence'. While they're not going to be developing a civilization any time soon, its cool to have an invertebrate that on many levels is closer to primate intelligence than many mammals.
FTFA:
"The definition of personality," she said, "is having repetition in your responses, for example, being consistently bold, or consistently shy, or consistently aggressive."
She went on to say that any individual octopus had random, inconsistent, reactions to the same stimuli on any random day.
So octopus are like women?
Oceanianica News (Deep under Chowder Bay): In an important press release today the octopuses involved in the Cowderbay Excursion report on their scientific excursion into the ape territory to assess the intelligence and personality of the horrific to look at four creatures with four limbs that only move on two of them that call themselves humans. The 32 members of the scientific team were specially trained in observational techniques that emphasized uniform behaviors so as to minimize the impact of their presence on the lower life forms being studied.
A four limbed creature who self identifies as "Miss Pronk" was extensively interviewed and examined. She attempted to use primitive externalized colored skin image projectors to get the 32 excursion members to react. Her primitive attempts at communication failed with what she called "PAL". Then the subject attempted to communicate using something she called "HDTV" by showing images of food. At the sight of a captive octopus the excursion members elected for a quick withdrawal back to the forward base camp in Chowder Bay (human's name for it). The members of the excursion ensured at all times to not reveal any individuality by using the uniform motion training instilled in all octopus from birth.
An assessment from the team after their safe return to Aquatica City was that the human subject lacked any personality during any of the tests. She failed to move on her two upper limbs and also failed to use her lower limbs except for moving about. In addition she had enclosed herself inside an flexible and rigid outer shell and refused all attempts to leave her shell so that we could examine her personality up close.
Naturally the humans require additional study. Under no circumstances should attempts be made to communicate with them until the safe return of the captive octopus hostages can be executed.
In addition it was discovered that while some humans have an additional appendage that is usually kept in the shell the human self identified as Miss Pronk failed to accept any of the advances by the others to have her interact with this appendage. For this reason we conclude that Miss Pronk has no personality.
The plural is octopodes, not octopi.
Ok, a couple of problems here:
- Standard video is not 24 frames per second, as the original article states. That's the speed for film, not video.
- 1080i HDTV is displayed at the same frame rate as standard definition TV. In PAL land, that's 50 fields per second, which makes 25 frames per second.
- Even at 720p's 50 full frames per second in PAL countries, that does not give the perception of smoother motion. SDTV will give you 50 half-resolution fields per second, and 720P will give you 50 full-resolution frames per second. The motion smoothness will be essentially the same. The real difference is the resolution delivered with each picture.
So, in other words, they're just like most slashdotters?
Fascism starts when the efficiency of the government becomes more important than the rights of the people.
"that it might see standard PAL video, at 25 fps, as a series of stills. She tried HDTV (50 fps)"
So she changed the resolution, and the framerate... and so she now does not know if it is the pixel desity or the framerate that made the difference. In addition, it would be good to note the display type as analog and digital displays work differently...
I disagree.
How we know is more important than what we know.
You're kidding right? If anything slashdoters would misread HGTV as HDTV.
This almost seems like an Ig Nobel coming in early. But being that this is the holiday season, I'll bite, at the expense of our Australian folks.
She recruited 32 gloomy octopuses from the waters of Chowder Bay.
Um, not for me to peck around at Australian dialect, but I think the proper word would be incarcerated.
Previously, researchers have reported little success when showing video to octopuses.
WTF?!?! Austrailian scientists: "Hey, what should we do this afternoon?" "Ah, let's show some video to the octopi." Try "Buckaroo Banzai," I think that they will like that one. It's kinda funny, if you understand octopi humor. "Miami Vice" is right out.
She tried HDTV (50 fps) and her subjects reacted to the videos of a crab, another octopus, or a swinging bottle on the end of a string.
After this treatment, I'd grab for the bottle in an instant.
A further discovery is that octopuses show no trait of individual personalities, even though they exhibit a high level of intelligence.
Just the other day I tossed a chick out of the bed, and said, "You *really* have a great personality, but you are so cold and slimy."
Schroedinger's Brexit: The UK is both in and out of the EU at the same time!
But whether you'll observe consistent responses to stimuli will depend on whether you're (a) measuring the right responses and (b) using the right stimuli. In this case, the stimuli were video images. Other researchers have found personality differences when using real stimuli. Maybe there is something about video stimuli that overwhelms individual differences?
I also have no personality and prefer HDTV!
No, octopuses are not inherently evil. You are thinking of krakens.
They whose government reduces their essential liberties for temporary security, receive neither liberty nor security.
I want to thank all of the noble Slashdot readers who tagged this story "Pronk," yet again proving their intelligence and foresight in picking a tag which I am sure will occur again and often in the future. Their brave efforts at usefully categorizing articles never ceases to astound.
Slashdot is a pretty cool guy eh posts dupes and doesn't afraid of anything.
Coz when the octopi rise up and enslave us, we will know how to curry favour with our new masters.
Mmmm, curried octopus...
Quidnam Latine loqui modo coepi?
"A further discovery is that octopuses show no trait of individual personalities, even though they exhibit a high level of intelligence."
In other words, they are like 90%+ of the human population. Except for the high level of intelligence part, of course.
What's hindering them from developing a civilization soon ( In geological time of course ;) is the fact that their lifespans are so short.
Humanity has been able to carry on numerous projects on a bigger scale than the average human's lifespan.
My personal idea about the prerequisite for a civilisation are :
- A decent way to interact with the environment (at least octopi have plenty of tentacles - dolphins on the other hand, however big their brain is, don't have the physically mean to put their brain at work on much things)
- A good a quite developed communication system (we humans have speech - octopi seem to have colour-changing communication)
- A life cycle including nurturing the small. If the parents of a specie have to take care of their kids during their first months/years, that gives also a chance to teach them (thanks to good communication) what they have learned to do with their arms. As opposed to animals whose children are 100% autonomous after birth and can immediately wander on their own.
That's where this whole business of "programmed death after reproduction" sucks. Not because 4-5 years is short, but because they are genetically programmed to self-destruct (or starve to death if the self-destruction glands are removed) not long after laying eggs (about the time the eggs hatch according to wikipedia).
There's no nurturing of the kids. Whatever cool and neat trick the parent octopi may have learnt dies with them. They don't get a chance to transmit it to their children.
Because of this no culture can be carried on, and with this : no civilisation.
But don't despair there's a kind of mutation called neoteny where some individual are able to reproduce without having acquired all characteristics of adult and still retaining some juvenile trait. Some future octopi may mutate and be able to reproduce, yet not die once the eggs hatches.

I still prefer octopi, with a light brown crust.
...who can only breathe under water and then you put him in a field of broccoli, refusing to return him to the salty depths until he has picked five times his own body weight. There are few things will motivate a Mexican Octo-man to work harder than such an immediate threat to his mortality. During my days in the Raj we were sure to keep a few brine filled baths of Mexican Octo-men handy come the spring. Harvesting time is upon us, fetch the Mexicans, eh what!
Now wash your hands.
Is that you?
Hail Eris, full of mischief...
E pluribus sanguinem
So I wouldn't pass judgement on octopus personality until somebody compares younger octopuses to older ones.
-1, irrelevant pedantry
We have borrowed words or phrases into this language that include non-native morphology. With the exception of some Latin and Greek plurals, we generally ignore the non-native morphology and use our own endings. So, for example, not only is it acceptable, but it is required to say "the La Nina" or "those La Ninas" and not "*La Nina" or "*the Nina" or "*those Las Ninas" or "*Estas Ninas". The lexical item is "La Nina", which cannot be decomposed into smaller morphemes like it can in Spanish.
Another example, also Spanish-related, is the presence of a number of words of Arabic origin in Spanish that begin with "al-", such as "algodon". Originally, this was the definite article in Arabic, but it is now a meaningless part of the word in Spanish and does not prevent the use of the native definite article.
Or, going back to English, it is generally correct to use a native s-plural for words of Latin origin, except in a small set of common loanwords: "formulas", "nexuses", "moratoriums", etc. Again, this is okay because English isn't Latin and isn't required to use Latin morphology. The fact that it does at all is a more a testament to the high standing Latin had and still has in our culture. Those non-native plurals are actually affectations, rather than the rule. You don't see people generally trying to use non-native plurals with words from other languages (the less important the language, the less likely we are to use anything other than the native s-plural).
So, my point is, it doesn't really matter what the original morphology was in the language we borrowed from. We borrowed the word as "kraken" and it is not decomposable into any smaller morphemes. The correct *English* plural is "krakens" and not "kraker", "kraks" or "krakulations".
For the pedant in all of us, the GP is correct. Etymonline explains how the -pi inflection results from an overgeneralization of the latin -us to -i pluralization (eg. status -> stati, terminus -> termini), but octopus is Greek (oktopous), not Latin, and the plural of pous (foot) is podes.
Unforutunately (of fortunately, depending on your stance), many of these words are losing their original inflectional category and are being "regularized" to the more Englishy -es (octopuses, statuses, terminuses). Many dictionaries (or the one you provided) don't even list "octopodes" as a plural (and they even list "octopi" since it's taken on a kind of folk-correctness). In order of historical correctness, it would be "octopodes" > "octopuses" > "octopi". In order of usage (and general acceptance by the masses) it would be "octopuses" > "octopi" > "octopodes"
Now, if we all spoke Chinese or Japanese, there would almost be no such thing as "plural inflection" (imagine all nouns being like mass nouns... "one octopus", "two octopus").
Sounds a bit like a guy I dated a few years back. He was all over me like an octopus, had no personality and lit up when he saw the latest technology.
But slashdot readers wouldn't be like that, would they !
I don't know. The mods are on crack again. Just go with the flow.
:P
In fact, parent and I are both losing karma for this. We are getting modded up Funny (+0 Karma), and then getting modded down (-1 Redundant/Flamebait/Troll). So even though the resultant post scores are high, we are actually going backwards.
Meh, I have karma to burn
It is a Scandinavian word, so the correct plural form would be kraker.
"Form is a Latin word, so the correct singular form would be forma, with plural formae."
That's about how linguistically defensible your complaint was.
Oh, that's just too punny -- only I'm not sure if you meant it, or just made a typo.
For those not familiar with Japanese, otaku is the word for "nerd" -- generally not in any positive sense. The word stems from the roots o-, being a generic honorific prefix to refer to things not your own (simply speaking), and taku or "residence", the underlying implication being someone who never leaves the house.
Meanwhile, tako is Japanese for "octopus".
I once heard of an idea for opening a chain of Mexican-themed seafood fast-food restaurants around Japan, called "Tako Taco"...
Cheers,
"What in the name of Fats Waller is that?"
"A four-foot prune."
Come to think of it, I think the plural of 'octopus' may be 'sushis'.
Umm, imagine a Mexican with 8 arms.
Octopi have only six arms. The other two are legs. (Six appendages for manipulating objects, two for pulling themselves along. And one of them doubles as a sex organ!)
It is dangerous to be right when the government is wrong.
Except in Japan, where all of them do ;).
Forget magic. Any technology distinguishable from divine power is insufficiently advanced.
