Chimp vs human! - Working Memory test



"Ayumu the chimpanzee has made headlines around the world for his ability to beat humans on memory tests, in both speed and accuracy. Does Ayumu's ability force us to reconsider our assumptions about human superiority to other primates?"

I've seen these experiments before. There are even apps where you can attempt to beat the scores and times of Chimpanzees (such as 'Ape Test'). Their cognitive abilities, i.e. 'intelligence', are clearly superior to homo sapiens in this particular area. But why? How does this ability benefit them in their natural habitat? I've yet to read of a convincing answer. As our favorite Vulcan would say, "Fascinating".

The Discovery of Dolphin Language

BREAKING NEWS


We Are Not Alone

The Discovery of Dolphin Language

For immediate release—November 2011

Key words: Dolphin, Cetacean, Echolocation, Cymatics, Holography, Language, CymaScope.
Researchers in the United States and Great Britain have made a significant breakthrough in deciphering dolphin language in which a series of eight objects have been sonically identified by dolphins. Team leader, Jack Kassewitz of SpeakDolphin.com, ‘spoke’ to dolphins with the dolphin’s own sound picture words. Dolphins in two separate research centers understood the words, presenting convincing evidence that dolphins employ a universal “sono-pictorial” language of communication.
The team was able to teach the dolphins simple and complex sentences involving nouns and verbs, revealing that dolphins comprehend elements of human language, as well as having a complex visual language of their own. Kassewitz commented, “We are beginning to understand the visual aspects of their language, for example in the identification of eight dolphin visual sounds for nouns, recorded by hydrophone as the dolphins echolocated on a range of submersed plastic objects.”
The British member of the research team, John Stuart Reid, used a CymaScope instrument, a device that makes sound visible, to gain a better understanding of how dolphins see with sound. He imaged a series of the test objects as sono-pictorially created by one of the research dolphins.

In his bid to “speak dolphin” Jack Kassewitz of SpeakDolphin.com, based in Miami, Florida, designed an experiment in which he recorded dolphin echolocation sounds as they reflected off a range of eight submersed objects, including a plastic cube, a toy duck and a flowerpot. He discovered that the reflected sounds actually contain sound pictures and when replayed to the dolphin in the form of a game, the dolphin was able to identify the objects with 86% accuracy, providing evidence that dolphins understand echolocation sounds as pictures. Kassewitz then drove to a different facility and replayed the sound pictures to a dolphin that had not previously experienced them. The second dolphin identified the objects with a similar high success rate, confirming that dolphins possess a sono-pictorial form of communication. It has been suspected by some researchers that dolphins employ a sono-visual sense to ‘photograph’ (in sound) a predator approaching their family pod, in order to beam the picture to other members of their pod, alerting them of danger. In this scenario it is assumed that the picture of the predator will be perceived in the mind’s eye of the other dolphins.
When Reid imaged the reflected echolocation sounds on the CymaScope it became possible for the first time to see the sono-pictorial images that the dolphin created. The resulting pictures resemble typical ultrasound images seen in hospitals. Reid explained: “When a dolphin scans an object with its high frequency sound beam, emitted in the form of short clicks, each click captures a still image, similar to a camera taking photographs. Each dolphin click is a pulse of pure sound that becomes modulated by the shape of the object. In other words, the pulse of reflected sound contains a semi-holographic representation of the object. A portion of the reflected sound is collected by the dolphin’s lower jaw, its mandible, where it travels through twin fat-filled ‘acoustic horns’ to the dolphin’s inner ears to create the sono-pictorial image.”
The precise mechanism concerning how the sonic image is ‘read’ by the cochleae is still unknown but the team’s present hypothesis is that each click-pulse causes the image to momentarily manifest on the basilar and tectorial membranes, thin sheets of tissue situated in the heart of each cochlea. Microscopic cilia connect with the tectorial membrane and ‘read’ the shape of the imprint, creating a composite electrical signal representing the object’s shape. This electrical signal travels to the brain via the cochlea nerve and is interpreted as an image. (The example in the graphic shows a flowerpot.) The team postulates that dolphins are able to perceive stereoscopically with their sound imaging sense. Since the dolphin emits long trains of click-pulses it is believed that it has persistence of sono-pictorial perception, analogous to video playback in which a series of still frames are viewed as moving images.
Reid said, “The CymaScope imaging technique substitutes a circular water membrane for the dolphin's tectorial, gel-like membrane and a camera for the dolphin's brain. We image the sono-picture as it imprints on the surface tension of water, a technique we call ‘bio-cymatic imaging,’ capturing the picture before it expands to the boundary. We think that something similar happens in the dolphin’s cochleae where the sonic image, contained in the reflected click-pulse, travels as a surface acoustic wave along the basilar and tectorial membranes and imprints in an area that relates to the carrier frequency of the click-pulse. With our biocymatic imaging technique we believe we see a similar image to that which the dolphin sees when it scans an object with sound. In the flowerpot image the hand of the person holding it can even be seen. The images are rather fuzzy at present but we hope to enhance the technique in future.”
Dr Horace Dobbs is Director of International Dolphin Watch and a leading authority on dolphin-assisted therapy. “I find the dolphin mechanism for sonic imaging proposed by Jack Kassewitz and John Stuart Reid plausible from a scientific standpoint. I have long maintained that dolphins have a sono-visual language so I am naturally gratified that this latest research has produced a rational explanation and experimental data to verify my conjectures. As early as 1994, in a book I wrote for children, Dilo and the Call of the Deep, I referred to Dilo's ‘Magic Sound’ as the method by which Dilo and his mother pass information between each other using sonic imaging, not just of external visual appearances, but also of internal structures and organs.”
As a result of Reid’s bio-cymatic imaging technique Kassewitz, in collaboration with research intern Christopher Brown, of the University of Central Florida, is beginning to develop a new model of dolphin language that they are calling Sono-Pictorial Exo-holographic Language, (SPEL). Kassewitz explained, “The ‘exo-holographic’ part of the acronym derives from the fact that the dolphin pictorial language is actually propagated all around the dolphin whenever one or more dolphins in the pod send or receive sono-pictures. John Stuart Reid has found that any small part of the dolphin’s reflected echolocation beam contains all the data needed to recreate the image cymatically in the laboratory or, he postulates, in the dolphin’s brain. Our new model of dolphin language is one in which dolphins can not only send and receive pictures of objects around them but can create entirely new sono-pictures simply by imagining what they want to communicate. It is perhaps challenging for us as humans to step outside our symbolic thought processes to truly appreciate the dolphin’s world in which, we believe, pictorial rather than symbolic thoughts are king. Our personal biases, beliefs, ideologies, and memories penetrate and encompass all of our communication, including our description and understanding of something devoid of symbols, such as SPEL. Dolphins appear to have leap-frogged human symbolic language and instead have evolved a form of communication outside the human evolutionary path. In a sense we now have a ‘Rosetta Stone’ that will allow us to tap into their world in a way we could not have even conceived just a year ago. The old adage, ‘a picture speaks a thousand words’ suddenly takes on a whole new meaning.”
David M. Cole, founder of the The AquaThought Foundation, a research organization that studied human-dolphin interaction for more than a decade said, “Kassewitz and Reid have contributed a novel model for dolphins' sonic perception, which almost certainly evolved out of the creature's need to perceive its underwater world when vision was inhibited. Several conventional linguistic approaches to understanding dolphin communication have dead-ended in the last 20 years so it is refreshing to see this new and highly-nuanced paradigm being explored.”
The human capacity for language involves the acquisition and use of a complex system of vocal sounds to which we attribute specific meanings. Language, the relationship between sounds and meanings evolved differently for each tribe of humans and for each nation. It is generally believed that the human language faculty is fundamentally different from that of other species and of a much higher complexity. The development of vocal language is believed to have coincided with an increase in brain volume. Many researchers have wondered why dolphins have brains comparable in size with those of humans, considering that Nature creates organs according to need. The Kassewitz team’s findings suggest the large dolphin brain is necessary for the acquisition and utilization of a sono-pictorial language that requires significant brain mass.
Dolphins enjoy constant auditory and visual stimulation throughout their lives, a fact that may contribute to their hemispheric brain coordination. The dolphin’s auditory neocortical fields extend far into the midbrain, influencing the motor areas in such a way as to allow the smooth regulation of sound-induced motor activity as well as sophisticated phonation needed for production of signature whistles and sonopictures. These advantages are powered not only by a brain that is comparable in size to that of a human but also by a brain stem transmission time that is considerably faster than the human brain.
Kassewitz said, “Our research has provided an answer to an age-old question highlighted by Dr Jill Tarter of the SETI Institute, ‘Are we alone?’ We can now unequivocally answer, ‘no.’ SETI’s search for non-human intelligence in outer space has been found right here on earth in the graceful form of dolphins.”

HOW DOES OUR LANGUAGE SHAPE THE WAY WE THINK?

By Lera Boroditsky

"For a long time, the idea that language might shape thought was considered at best untestable and more often simply wrong. Research in my labs at Stanford University and at MIT has helped reopen this question. We have collected data around the world: from China, Greece, Chile, Indonesia, Russia, and Aboriginal Australia. What we have learned is that people who speak different languages do indeed think differently and that even flukes of grammar can profoundly affect how we see the world. Language is a uniquely human gift, central to our experience of being human. Appreciating its role in constructing our mental lives brings us one step closer to understanding the very nature of humanity."

Being married to a someone from Hong Kong and a woman, I can attest to the conclusion above. :-)

Belgian says he was alert but mute for 23 years

"By RAF CASERT
BRUSSELS (AP) - For 23 torturous years, Rom Houben says he lay trapped in his paralyzed body, aware of what was going on around him but unable to tell anyone or even cry out.
The car-crash victim had been diagnosed as being in a vegetative state but appears to have been conscious the whole time. An expert using a specialized type of brain scan that was not available in the 1980s finally realized it, and unlocked Houben's mind again.
The 46-year-old Houben is now communicating with one finger and a special touchscreen on his wheelchair.

"Powerlessness. Utter powerlessness. At first I was angry, then I learned to live with it," he said, punching the message into the screen during an interview with the Belgian RTBF network, aired Monday. He has called his rescue his "renaissance.""

Pigs Prove to Be Smart, if Not Vain

Recent discoveries from the nascent study of pig cognition offered evidence that pigs were quick learners, slow to forget and similar to humans in many ways.

"We’ve all heard the story of the third Little Pig, who foiled the hyperventilating wolf by building his house out of bricks, rather than with straw or sticks as his brothers had done. Less commonly known is that the pig later improved his home’s safety profile by installing convex security mirrors at key points along the driveway."

Girl, two, with IQ of 160 praised for 'wonderful imagination'

A two-year-old girl has been found to have an IQ of 160, making her among the top 0.03 per cent of the population in Britain.

"Karina Oakley was asked to question numbers and complete challenges in several different categories, including verbal ability, memory, handling a pencil and numbers and shapes.



Some of the answers showed a "wonderful imagination", according to Prof Joan Freeman, the child psychologist who used the Stanford-Binet IQ intelligence test.

When asked, 'What do you use your eyes for?' Karina answered: 'You close them when you go to sleep' and then also said: 'You put your contact lenses in them'.

Karina, from Guildford, Surrey, has an IQ 60 points above the mean for the population.

Prof Freeman said a score of 160 was rare, but was not unheard of. The test goes up to 170.

Her mother, Charlotte Fraser, who previously worked in marketing, and her father, Nick, a computer programmer, said their daughter had a very good memory.

Her mother said: "Quite a lot of people had said to me that Karina is quite smart, quite bright, quite clear with her speech and quick to pick things up.

"So I looked Prof Freeman up on the internet, and gave her a call to see if she would see her and get her tested. It was just a bit of fun really."

She added: "She seems to be quite aware of her surroundings, what's going on around her, she is very observant, she talks all the time, asks questions all the time.

"The nature verses nurture argument is a very interesting one.

"I have stayed at home with her for almost three years, I have always talked to her a lot, always tried to answer her questions, we do a lot of things, we go to the park and we are part of various groups. That must make a difference.

"I do not know whether it is that, combined with something that she was born with."

After the test, the professor concluded: "Karina is a lovely, responsive and friendly little girl. She is more than very bright and capable, she is gifted."

She added: "Karina enjoyed the test. The pleasure she took in the mental challenge in itself I have found to be a sign of intelligence."

Another two-year-old girl, Elise Tan-Roberts, from Edmonton, north London, was recently found to have an IQ of 156. She can count to 10 in English and Spanish and recite the phonetic alphabet. She could also name 35 capital cities."

Two-year-old girl with IQ of 156

A two-year-old girl has become the youngest member of Mensa with an estimated IQ of 156.

"Elise Tan-Roberts was five months when she spoke her first word, calling her father "Dada". She was walking three months later and running two months after that.

Before her first birthday should could recognise her written name and by 16 months she could count to 10. She is now able to do the same in Spanish.

Inspired by the story of Georgia Brown, who also joined Mensa when she was two, her parents Louise and Edward, from North London, took her last month to see Professor Joan Freeman, a specialist education psychologist.

After Elise completed a 45-minute IQ test, Prof Freeman concluded in a written report that Elise was "more than very bright and capable - she is gifted."

Only those with an IQ of 148 and above, the top two per cent, qualify for Mensa. The average IQ is 100. For a child her age, Elise is in the top 0.2 per cent.

Her father, a 34-year-old motor consultant, said: "Our main aim is to make sure she keeps learning at an advance pace.

"We don't want to make her have to dumb down and stop learning just to fit in. But she's still my baby. I just want her to be happy and enjoy herself."

Carol Vorderman has an IQ of 154."

Two-year-old with same IQ as Einstein

Season 10 saw the first of Stephen Hawking's t...Image via Wikipedia

Oscar Wrigley, a two-year-old with the same IQ as Albert Einstein and Stephen Hawking, has become the youngest boy in Britain to be accepted into Mensa.

Published: 8:00AM BST 10 Oct 2009

"Assessors at the Gifted Children's Information Centre in Solihull said Oscar, with an IQ of at least 160, is one of the brightest children they have every come across.

He has been ranked in the 99.99th percentile of the population and has been ranked off the scale as the Stanford-Binet test cannot measure higher than 160.

Oscar's father Joe, 29, an IT specialist from Reading in Berkshire, said: "Oscar was recently telling my wife about the reproductive cycle of penguins.

"He is always asking questions. Every parent likes to think their child was special but we knew there was something particularly remarkable about Oscar.

"I'm fully expecting the day to come when he turns around and tells me I'm an idiot."

Mother Hannah, 26, told The Daily Mail: "He amazes everyone. We knew at 12 weeks he was extremely bright. He was unusually alert."

Mrs Wrigley, a housewife, added: "His vocabulary is amazing. He's able to construct complex sentences.

"The other day he said to me, 'Mummy, sausages are like a party in my mouth'."

Dr Peter Congdon, who assessed Oscar, said he was a "child of very superior intelligence".

"His abilities fall well within the range sometimes referred to as intellectually gifted. He demonstrated outstanding ability," he said.

John Stevenage, Mensa's Chief Executive confirmed Oscar had been accepted aged two years, five months and 11 days.

"Oscar shows great potential. Converting that potential to achievement is the challenge for his parents and we are delighted that they have chosen to join the Mensa network for support", he said.

The youngest British child to join Mensa is Elise Tan Roberts, from Edmonton, North London, at two years, four months and 14 days, with an IQ of 156."

Dolphin Speak Relies on Brevity

"Among the words we use most often, short ones like "I," "a" and "the" top the list. It turns out we're not the only ones who strive for this type of efficiency in the way we communicate. Dolphins, found a new study, do it, too.



It's the first evidence that another species follows one of the basic rules that defines all human languages: the law of brevity."
