Language

Prof. Evelina Fedorenko speaks with Scientific American reporter Gary Stix about her research demonstrating that “language and thought are, in fact, distinct entities that the brain processes separately.” Speaking about how large language models could be used to help scientists better understand the neuroscience of how language works, Fedorenko explains that "there are many, many questions that we can now ask that had been totally out of reach: for example, questions about [language] development.”

Researchers at MIT have found large language models “often struggle to handle more complex problems that require true understanding,” reports Kirimgeray Kirimli for Forbes. “This underscores the need for future versions of LLMs to go beyond just these basic, shared capabilities,” writes Kirimli. 

A study by researchers at MIT and elsewhere has found that both lawyers and non-lawyers use legalese when asked to write about laws, reports June Casagrande for The Los Angeles Times. The "researchers tested the hypothesis by asking 200 participants to write laws prohibiting crimes like drunk driving and burglary,” explains Casagrande. “Then they asked them to write stories about those crimes. The laws they wrote contained unnecessarily long, labyrinthine sentences with lots of parenthetical explanations crammed in. The stories, however, were written simply, without the parenthetical information stuffing.” 

Researchers at MIT have uncovered a possible reason why legal documents can be so difficult to read, finding that “convoluted legalese often acts as a way to convey authority,” reports Joe Berkowitz for Fast Company. The researchers “tested whether nonlawyers would end up using legalese if asked to write legal documents,” explains Berkowitz. “In the end, all subjects wrote their laws with complex, center-embedded clauses.”

Researchers at MIT have found that the use of legalese in writing “to assert authority over those less versed in such language,” reports Noor Al-Sibai for Futurism. “By studying this cryptic take on the English language, the researchers are hoping to make legal documents much easier to read in the future,” explains Al-Sibai.

DragonBot, an AI tool developed by the MIT Personal Robotics Group, “is designed to teach children empathy and social skills,” reports Neil Sahota for Forbes. “These interactions, while mediated through technology, are invaluable in nurturing the social and emotional growth of children,” writes Sahota.

Prof. Evelina Fedorenko has uncovered evidence that the human brain uses language for communicating, not reasoning, writes Carl Zimmer for The New York Times. “Other regions in the brain are working really hard when you’re doing all these forms of thinking, but it became clear that none of those things seem to engage language circuits,” she says. 

On NPR’s Short Wave, climate correspondent Lauren Sommer reports on MIT researchers using artificial intelligence to decode the secret language of sperm whales. Prof. Daniela Rus says, “it really turned out that sperm whale communication was indeed not random or simplistic but rather structured in a very complex, combinatorial manner.”

MIT researchers have used advancements in machine learning and computing to help decode whale vocalizations, reports Sarah Kuta of Smithsonian Magazine. “If researchers knew what sperm whales were saying, they might be able to come up with more targeted approaches to protecting them,” Kuta explains. “In addition, drawing parallels between whales and humans via language might help engage the broader public in conservation efforts.”

A new analysis of years of vocalizations by sperm whales in the eastern Caribbean has provided a fuller understanding of how whales communicate using codas, reports Will Dunham of Reuters. Graduate student Pratyusha Sharma explained that: "The research shows that the expressivity of sperm whale calls is much larger than previously thought."

New Scientist reporter Clare Wilson writes that a new analysis by MIT researchers of thousands of exchanges made by east Caribbean sperm whales demonstrates a communication system more advanced than previously thought. “It’s really extraordinary to see the possibility of another species on this planet having the capacity for communication,” says Prof. Daniela Rus.

Researchers from MIT and elsewhere have uncovered a phonetic alphabet used by sperm whales, which provides “key breakthroughs in our understanding of cetacean communication,” reports Brain Heater for TechCrunch. “This phonetic alphabet makes it possible to systematically explain the observed variability in the coda structure,” says Prof. Daniela Rus, director of CSAIL. “We believe that it’s possible that this is the first instance outside of human language where a communication provides an example of the linguistic concept of duality of patterning. That refers to a set of individually meaningless elements that can be combined to form larger meaningful units, sort of like combining syllables into words.”

Associated Press reporter Maria Cheng spotlights a new study by MIT researchers that identifies a “phonetic alphabet” used by whales when communicating. “It doesn’t appear that they have a fixed set of codas,” says graduate student Pratyusha Sharma. “That gives the whales access to a much larger communication system.” 

Using machine learning, MIT researchers have discovered that sperm whales use “a bigger lexicon of sound patterns” that indicates a far more complex communication style than previously thought, reports Lauren Sommers for NPR. “Our results show there is much more complexity than previously believed and this is challenging the current state of the art or state of beliefs about the animal world," says Prof. Daniela Rus, director of CSAIL. 

MIT researchers have discovered that sperm whales use a “much richer set of sounds than previously known, which they call a ‘sperm whale phonetic alphabet,’” reports Carl Zimmer for The New York Times. “The researchers identified 156 different codas, each with distinct combinations of tempo, rhythm, rubato and ornamentation,” Zimmer explains. “This variation is strikingly similar to the way humans combine movements in our lips and tongue to produce a set of phonetic sounds.”
